Tristan.... I just wanted to compliment you on your exemplary and unmatched attitude. In all the videos you've posted and shared over many years, you always exhibit an unwavering positive outlook; you are always perpetually optimistic; and you are always smiling from year to year. Whether you are aware of it or not, you're not only sharing information and teaching your audience a little bit about being a superyacht captain, you're actually teaching your audience a much more valuable lesson -- How to be happy and enjoy life, and how to make the best of every situation. So thank you for sharing your videos and positive attitude with all of us. Wishing you all the best in all your present and future endeavors.

I can only speak from an aviation point of view, but when connecting ferrous and non-ferrous materials we always used a zinc-chromate jointing compound, it would always stay "wet" and was very effective at preventing corrosion.

gets strange, Solas requires 37.5% of passangers per side. so 12... with 2 life rafts per zone if under 36 passengers. since they only have 2 life rafts. now 37.5% would be 32 pass passengers for a 12 person life boat. Means it should be 32.

One of the best things I’ve used is Duralac it’s used on aircraft to stop corrosion between aluminum and stainless steel, also used a lot on sailboats on rigging etc it’s by far the most effective product. The t top needs some nylon washers and a tiny bit of duralac

12, safe working load, bushings are a good idea to isolate SS and aluminum. Lifting gear on tender shoulder be more robust….Glad to have you back!

I never realized how much attention to detail you have. That is TRULY down to the nuts and bolts of your ship. I guess that should make the owner very confident that he picked the right man to command his yacht. You seem to be treating it like it is your own, and that is in my opinion, the mark of a great person and leader.

thanks for the explanation, very clear and simple language.

SWL (Safe Working Load) is defined as the maximum safe load that the lifting equipment can lift, move, suspend, and lower down to the ground without any problem of breaking.

I was all in on the tender but then saw the welding on the t-top, (I'm sure its fine but they usually look much better), the small backing plate and lack of galvanic corrosion mitigation. All of these are very easy fixes (as are the addition of additional tiedown points. Safe working load. Thanks for taking us along.

Tristan you're absolutely right about the contact between stainless and aluminium. You must have a separation or you will get corrosion. Also, those lifting eyes need beefing up. There will be a huge amount of strength in sheer and pull but I always think if it doesn't look right, it probably needs improving. Good finds that will increase safety and reliability.

It should be noted that the rate at which corrosion will occur in a mostly dry environment isn't terribly alarming. However, it still is a concern over time. At a minimum some paint on the two surfaces will help or any number of coatings made specifically for this application. But, a more permanent bushing/spacer/etc. made from a non-metallic material would be ideal.

So happy to see you as Captain Tristan again!

hi mate me again, galvanic corrosion occurs when the electrical conductivity has a large potential difference between the 2 metals, alloy and S/S has a fair gap between them so one will become an anode and the other a cathode if connected with an electrolyte ( salt water ), I will probably get shouted down for this by internet experts but! you have 2 options in my opinion to keep the corrosion away, 1. separate the contact of the S/S with rubber or some inert material to prevent contact, including the through hole. 2. attach a zinc anode ( just a piece of square stock and shape it slightly for more contact ) inside the cabinet out of the way and this will corrode instead of the aluminum as the potential difference is larger between it and S/S . hope this helps mate, love your work

My thought is that you could use a zinc-plated bolt instead of a SS bolt and then just replace the bolt every few years (however much is needed). Depending how wet the actual joint gets with saltwater, it may or may not corrode substantially.

@@viveksawhney5691 good idea however I dont know if the zinc plating applied to bolts is porous enough as it is hot coated and oxidizes once it cools closing and hardening the surface, but!!! soft zinc washers would do the trick but you would have to change all the washers when corroded as apposed to 1 or 2 ingots, good thinking though

“Ooo a new SYC video. This should fun!” *immediate pop quiz* 😮😅🤓

Listen to “your gut” with the amount of experience you have, you just know when somethings “not quite right”. In my experience I would want bushings on that t-top and definitely reinforce those lifting points.

Think you need full compliment capacity on each side according to Solas, so 12 POB in all. Nylon washers and bushes are a good idea between stainless and aluminium. The fact that the tender is mostly out of the water may have prevented major issues, but is no guarantee.

Thanks for continuing the tour! Great detail.

SWL is safe working load So great to see you back in the captain’s chair Look forward to seeing this boat and your adventures

SWL means Safe working Load, Max number of passengers = 12. I would advise the brackets to lift the boat to be strengthened. also look at a different way of strapping the boat to lift it so you don't have to remove the canopy every time. Look into spreader bars. I'm so glad your back being a captain, I like this content

Galvanic corrosion can occur between aluminum and stainless steel, especially in the presence of salt water. However, SS is not a very reactive metal, so the occurrence will be limited. A nylon washer and silicon inside the hole would be the best protection.

With US Navy aircraft we used to use water-displacement and anti-corrosion coating on all fasteners then mix and spray on a sealant coating. Then paint if needed. Once again I really love these kinds of videos from you. It is nice to be able to go along with you on all your inspection and the thoughts you include us in. The interaction is fun.

What about the crew please?😊 is the mrs on board?

SAL safe working load. 12 person life raft can carry 18 (12+ 6 overload ). Great video.

Great episode! Thanks for sharing! Cool crane operator controls! 👍👍

Very nice Bright Work !

I forgot, 12 persons, Safe Work Load, which should have a minimum safety factor of 1.5 which means what ever the plaque says it will break at 1.5 times the weight, i would be surprised if the factor was only 1.5, my lifting slings are a safety factor of 8, which means the slings fail at 8 times the SWL

There is an opinion that where there is no contact with sea water, different metals can be combined, but theorists forget about condensation, various leaks and even salty air. Aluminum is an anode for all metals except zinc and magnesium, which means that when in contact with other metals, aluminum will undergo electrochemical corrosion (aka galvanic corrosion). If we add electric current to this process, then electrocorrosion will occur and it is much stronger and faster than galvanic corrosion. The solution is in zinc anodes attached to the body, which need to be regularly checked and replaced as they are quickly consumed. As for attaching equipment to an aluminum body, you need to use plastic spacers and insulation (Tef-gel - the corrosion eliminator based on Teflon). But in general, pay attention to the kingstons, stern tube of the shaft, rudder blade shafts. Do not use antifouling with copper oxide as a base. PS: Even a copper coin falling into the hold can cause significant corrosion, so on some ships the captain takes coins from passengers) - beware of getting dissimilar metals! Also be careful with shore power, which must pass on board the aluminum vessel through a galvanic isolator or isolation transformer.

Hi Tristan! Great to see you back 'on board'!! SWL - Safe Working Load. Max crew/pass. for the liferafts = 12 as one side of the vessel may not be accessible when required to 'leave' the vessel. The stainless bolts on the tender cover supports; if it is going to spend most of its time in the cradle and in a dry environment I doubt you'll need to be too concerned with the electrolysis issue so long as the seal wheel the support poles enter the cabinet are sealed sufficiently. Keep the cabinet aired so it stays dry and I would spray some Techtyl (or something similar) to provide some moisture protection over the bolts/nuts. The lifting lugs on the main tender on the bow - I think I'd like to have some 'knees' joining that upper plate (with the pad eyes connected to) down to the side of the hull to help distribute the land. From the video it would appear that all the load would be taken on the plate at the side where it meets the hull (if that makes sense?) Just a couple of thoughts!! I note the Australian Red Ensign on the aft flag pole!! Is she registered in Australia (I'm Australian) or have I got that wrong?

No doubt your engineer will be familiar but there is a product called Tef-Gel which is really good at preventing galvanic corrosion between dissimilar metals above the water. Also really good on threaded connections, particularly stainless steel for preventing galling. (If you’ve ever had a stainless nut and bolt weld themselves together, that’s galling. In both senses of the word!

Hi Tristan. In regards to galvanic corrosion, may I suggest having bushings made out of Delrin or ABS. Both should hold up in nautical usage. Delrin is machinable and has a slippery finish where as ABS you can bond epoxies to it. Depends on your present and future usages. Just a thought .

I would say she is able to safely carry 12 people in total guests/crew. Life raft either side so despite side the boat is tipping your still able to access one. SWL gussing (Short weight limit) the load capacity when the boom is at its shortest ( strongest position)

SWL means safe working load. (WLL is work load limit) 12 souls on board total considering she is capable of having 8 guests and 4 crew. and yes the the Aluminium will act as the anode and corrode, it should have a bushing or e en a nylon bolt.

The answer is 12, - enough for the crew and passengers plus 50% redundancy. SWL= Safe Working Load , which is a ratio of the Factor of safety applied to the lifting wire or the davit whichever has the least SWL. it is tested to double safe working load every 12 months (6 months if it is lifting crew).

good to see you back! how is the jibanator?

Well, i have seen an online sales video of this ship, and there is a master bedroom for 2 people, 2 vip guest room with doublebeds and a guestroom with 2 single beds. That count’s as 8 passengers. Don’t know about the Crew facilities, but i guess there is a Crew of 4. In total 12 souls. SWL is short for Safe Working Load and is the Weight limit the crane legally can operate.

I'm a machinist with considerable experience building various machines, and working closely with Mechanical Engineers. My experience tells me that the backing plate on the lifting points for that boat are more than enough to lift that entire boat. Just for reference, a single 12mm machine screw with washer and nut bolting through a piece of heavy gauge sheet steel is rated for nearly 5 tons in tension. That setup you just pointed out has three stainless 8mm screws with a really large stainless backing plate bolted though, what is effectively. formed aluminum C channel. I would bet my life that one of those pad-eyes could lift the entire boat without a problem. Even if there were a problem. the aluminum C channel would show signs of deformation long before the screws or plate would ever yield. As to the strength of the shackle itself, and other associated hardware, I don't know. I would consult the technical literature that came with those pieces of hardware to know for sure. I can say that it doesn't look as strong as the mounting hardware, which is very solid.

Very interesting video! Thanks for posting.

Hi, you need delrin washers and Tefgel....latter is really good stuff. Old rubber tubes from cars or bikes (or buy new) are good to have around. Plastic sleaves or spacers are also good to have. Galvanic will happen even with humidity. It has to be remounted.

Thanks for the tips!

Nice to see the crane is from the Netherlands. I would advise to not use Nylon because it's hydroscopic. If you can get washers made from POM these do not absorb water and are much more resistant to UV radiation.

For the bolt there are many insulation products you can put on rapidly cause in sailing yacht we have same steel bolts on aluminium masts. Most common is tefgel, duralac is a good product too but it hardens with the time. Best solution would be doing some arnite bushings. It's really hard plastic UV resistant. Enlarging about 2 mm the radius of the hole in the aluminium so you will have room for kind of a thin cylinder that insulate bolt and aluminium combined with a top large head (like a washer, all in the same piece). You can find them on market on different lengths, they are used for up/down bowthrust boxes, that usually are aluminium alloy. Ask your engineer, he would know about this stuff. Hope I can be of help, I would like being hired and learn from you :)

12 people, safe working load, so proof load the crane to 3t. The dynemna lines are probably ok as long as they don't go over any hard edges, thimbles in the end would be nice but not necessary. The hardwear unless stamped with a rating, I would look at upgrading to rated rigging. The forward listing points looked more like a lashing point

SWL “safe working load” has been changed to “Rated Capacity” for cranes and WLL “working load limit” has replaced SWL on shackles and slings. They had to remove the word “safe” for legal reasons. Imagine that 😊

Hi Tristan. About the bolt on the hull for your top. If there is a spacer between your stainless steel and aluminium and the bolt is galvanized you might be lucky. That said. Check in with an marine engineer about this. He might have better insight about saltwater and isolation. About the loadpoints. Based on what I saw without knowing the structural details of the boat it seems specifically designed to perfectly spread the load. Aluminium is a pretty soft metal which likes to become fatigued. When you enlarge the plate without knowing what you do you run a decent risk of actually damaging the vessel. During my time at uni they gave us an example in which by removing some material they made the part more reliable and fatigue resistant. Making things bigger does not always equals better. You might actually damage stuff.

Thanks for the tour…

12 persons, Safe working Load, and insulate the different metals... bi metallic corrosion. Do a tour of the whole boat in one go. Access all areas! Owner cabin, crew space, engine room etc. There's a guy called Aquaholic. He knocks it all out in about 15 mins. Check out his vids!

12 obviously. Plus Captain ;-)

Excellent video 🚤🛥⛵️👍👍👍👏👏👏👏

Tristan, be very careful with that style of carabiner on the tender lifting strips. They must be used the correct way up, I had a situation a few years ago where a crew member clipped it on the wrong way up and it failed while lifting a jet ski. It was being used at a far lower load than it’s stated s.w.l.

As far as i understand, you could go two ways, either sperate the two metals, which might be a bit hard . Or you could make sure the two metals has a good connection, and then add an magnisuim anode if its mainly FW your ruuning in. It should corrode first, and will work in FW compared to zink which works better in salt water. Dont hang me up on this, but think worst case running in salt water the anodes would just be dissaper quite quick, but since its out of the water most time it would be easy to replace if needed. Also if anodes have a white layer on the outerside they wont work, even if there still is a lot of material left 12 peopel, so if you capsize there is one raft to put out on the side which are facing away from the water. SWL Safe working load, on the north sea we get hooks down that are 50 tons SWL, they big, and in bad wheater they go up and down quite a lot - makes interesting work with timing with sea. The ship is moving but the platform not.

Is Giv crewing with you this time Tristan?

I would say 14… yes x2 rafts but one could be untenable for use list of ship etc, also the Captain should ALWAYS be the last person off the Ship after seeing to the safety of his/hers passengers & crew. Also SWL is Safe Working Load, as to the ratchet straps as the Captain it’s your call, but if Lorry Drivers use them ALL over the world to secure some big unusual sized/shaped loads… surely if used correctly there good enough for your “little” boat to be secured down, but again Captain that’s just my humble opinion & your the person in charge making those kind of decisions on a day to day basis. Safe sailing 😊.

For the stainless to Aluminium connection, use Duralac jointing compound. It is used extensively on yacht masts where the stainless standing rigging connects to the aluminium mast. mast.

Thanks for sharing

You are correct there should be an isolation washer in between the stainless and aluminum. They make a nylon washer that would go over the bolt to isolate the two metals. It could be find by finding a cathodic protection supplier. We used them on base in Afghanistan specifically for that reason, But I forgot who our supplier was that we go them from.

To prevent galvanic corrosion, yes install rubber separators, SWL is short form for "Safe Working Load" of the crane. Finally you are allowed 12 persons on board. You have one life raft on each side in case the ship keels to one side so the other is unusable. Yes I worked around boats / ships for many years.

SWL: safe working load. Maximum number of persons on board:12. I am not an expert on corrosion, but would like to point out that structure is not aluminium, it is aluminium alloy. There are numerous aluminium alloys, all with different corrosion characteristics. The stainless steel is most probably austenitic stainless (a term which covers a multitude of sins), and again, the corrosion behaviour will depend upon the precise chemical and microstructural compositions. Then you also need to consider the composition of the nuts and bolts. Are they mild steel, high tensile steel or stainless? I would seek the advice of the boatyard which does your maintenance and service. You could also note which joints get wetted by seawater and remove the the nuts and bolts from those joints 2-3 times a year and visually inspect for corrosion. The structure is not going to collapse if bolts are removed one at a time for just a minute or so.

Check out tec 12 in terms of dyneema line, absolutely incredible stuff. I know flints stock it here in the uk. Would be inclined to agree that the plates under those lifting eyes want to be larger!

I would look into a Zinc petroleum which Provides corrosion protection to metal surfaces. ZINC DUST PETROLATUM lowers friction and reduces wrench torque. It is ideally used to prevent seizing during assembly or disassembly of threaded or unthreaded components fabricated from aluminum or its alloys, engaged with components fabricated from similar or dissimilar metals. It is also intended to provide corrosion protection to the metal surfaces.

Great video, you look like your really enjoying yourself.

The private yacht Espiritu Santo is a 31.7 meter vessel which can legally accommodate 8 passengers and 4 crew, so I'm assuming that the second life raft could be used as a back up or for provisions, or whatever.

Captain I am a fan BUT you should get with aquaholic guy. He does a mean Yacht tour. A yacht with more than 12 persons total (is considered a ship) but less 36 needs two lift rafts and has strict regulations. Most Yacht owners elect to keep total capacity of Passengers + Crew to 12 or under I say your Yacht is governed by by the 12 rule. Since there is a crew of ?? Min is 2 max 8 for Yacht this size. Let's split round down, 4 crew + 8 passenger. What do I win.

All in all - so far and we did not see the interior, yet - this seems to be a real step down compared to AWOL. But on the plus side we notice that this is an owner ship. So no fancy cooks on board but relatively calm life, on the other hand. We are excited to see how much crew there will be, assumed is a staff of 5.

12, if the vessel is listing you can only deploy one side.

Nice to see the crane is build in Leeuwarden, Netherlands, and SWL stand for Safe Working Load, also know as WLL, Working Load Limit, This is the max weight the crane is designed and tested for, for everyday use, it may lift more if occasionally needed, but not reconmended

If you want to eliminate the ratchet strap, you may want to consider a short length of tow strap (or similar, perhaps heavy line) terminated with eyes - attach the turnbuckles to the eyes and secure it down the same. That anchor point on the boat is better than any welded eyelets, after all, so you can keep using it and switch to a tensioning system you prefer.

Another great video. I am by no means an expert on boats, but I do know a little bit about welding. I will try to say this as gently as possible. The welds on that tender look like they should be ground off and re-welded. Especially the welds on the stainless steel. At least the aluminum welds looked better, but only because they were painted over. I hope you get this address when you are having the rest of your concerns fixed.

Steel/aluminium connections in the marine applications are used to be made via bimetallic plates. Of course I'm not sure if they are used in the tender.

Interesting , Thank You

Regarding the galvanic corrosion. Could defenetly have an impact, especially when stainless steel is not ventilated. Not sure how critical it is. It can hold for some time be for it get critical. However if you want to keep the yacht to Lloyd’s standard, I am sure your chief will go nuts about this

That was an interesting tour Tristan. The tender is a really cool boat. Might be a good idea to put some bushes and rubber washes between the stainless and aluminium, just to be on the safe side, though I think it would take decades for any rust to be a problem as that part of the boat is pretty dry. SWL is Safe Weight/Working Limit (depends on industry and country). As for the life boats and carrying capacity, it certainly wouldn't be 24, maybe 12 but that is a guess. Guessing it has to do with redundancy with the life boats.

Hi Tristan. Put some plastic bushing between de aluminium end steal connection. It is good to have protection between the 2 divrend metals . You don't want corrosion on your new ship.

Thanks again for let us join your job 🫡 Do you miss AWOL, and do you care about the ship like a child who moved? 😁😁😁

Up to twelve people , SWL , is safe working load . my view on the alloy tender is , corrosion has not started there yet , so may be leave it ,but if it worries you , you will have to make the bolt holes bigger and put a small rubber sleave around the bolt , and use hard plastic washers on the bolt too .

Safe working load..12..and definitely insulate !

Swl = Safe Working Load . Life rafts a good question as depends what class the vessel is registered as. It difficult to assess how the vessel is classed as the boat launching davit should have a red band painted around it to signify that it can be used to launch boats without crew but as it has no band it could be said it is ok to launch boats with crew onboard if that's the case then all strops lifting points etc should be certified up to the job, well done on investigating this and the dissimilar metals issue, its the attention to detail which makes the difference nice one, keep the videos coming.......

Safe working load. Turnbuckle is correct. Agreed, ideal conditions for galvanic corrosion. Regardless of the presence of the silicone, the humid environment will be enough to begin the process. Front lifting points seem a little undersized. In saying that, appears they're expecting little to no weight on the front with those 3x M6 screws holding each point on. The way the center lifting point is slung shows how large a portion of the weight is on the rear. But for the cost of a bit of flat bar in place of that small plate, I'd be replacing it.

100 right, it’s is tricky to launch when theres a bit of a roll.

Re the possible galvanic corrosion on the aluminum tender.. On the "custom-made yacht tender" I would call the builder and have them send a tech to the boat's current location and conduct any repairs or upgrades. A phone call takes care of that project. "SWL" - Safe Work Load. Or the safe operating load, safe working load, safe weighting load. Whichever. It's just an acronym for "hey don't try lifting that heavy thing or bad stuff will happen".

Galvanic corrosion is a problem - use a bushing OR Tefgel paste.

The stainless steel bolt to alu connection can corrode the aluminium edges of the center console bolt hole. Adding a PTFE washer between the 2 materials will fix that right up. Additionally you could add a corrosion inhibiter compound like CA1010 chromate free mastinox on the shank of the bolt before install.

My 2c worth, restricted to 12 Pax unless Doctor is on board. If like the Andrea Doria, you may only be able to deploy from one side. So, the Pax get off and the crew have to paddle around in their survival suits until help arrives ,,,,, But I am sure you know the correct answer, LOL.

Stainless and Aluminium do react but its very slow. Maybe just do any isolation work as a winter job.

Those forward lifting points are going to keep me awake tonight!

You are 100% correct the tender needs attention concerning rust. The stainless and Alu MUST be isolated. SWL = Swing Weight Limit ?
