Please discuss the Corrosion Prevention related to the mast stays and the anchor chain(s)!

Interesting information. The chain locker almost need to be coated with truck bed liner.

When building aluminium boats in South Africa, a company (name left out for reason) poured Lead directly into the keel box. They did not use any liner, nor did they use any other method to isolate the Lead from the aluminium. A few years on and the boat was taking on water and had to be pulled out and they found that the lead had reacted with the aluminium causing lots of corrosion. The company had sealed the lead with a top plate and only minimum water sat in the bilge but was enough to start the process. The repair ($60,000) was comprised of cutting off the keel, building a new box around the existing poured lead keel which was epoxied and isolated before installing into the new box. After seeing the repair I understood that poured lead has a possible problem. Your new build is going to be beautiful boat and congratulations on the new build!

Excellent video. But I do not understand how, in the case of Distant Shores IV, the poured lead will be isolated from its aluminum enclosure. How is the Dutch construction method going to avoid the deficiency of the South African builder you are describing in this comment?

@@arthursalvadore I am waiting to see as well Arthur. If the Lead was bricked first in a mold then transferred to their new boat which had the areas epoxied that might work.

@ 9:51, the connection of the compression post for the mast with the upper deck. That just looked like an afterthought to me. I guess I was expecting a more direct and solid connection to the mast step. I love everything I see so far about the boat, but as a former ship/pipe welder, that just looked weak to me. Other than that, beautiful craftsmanship, makes me proud to be Dutch.

Small point- electrolysis and galvanic corrosion are similar but not the same thing. Galvanic corrosion is caused by dissimilar metals in contact when immersed in an electrolyte. Electrolysis is the result of potential current between two objects and is usually caused by stray electrical current.

When I was about college-age most of the West Coast of America alloy Boats were hitting 25 to 30 years old. I made a lot of money paying for college chopping rotted aluminum out of the bottoms of mid-eighties to early 90s boats. Postmortem the biggest issue is pooled water, that killed more boats than anything else. Isolation is fine, but in my experience it slows but does not fully stop corrosion. Duramax makes synthetic Stern bearings that I would have preferred over a coated bronze one. The other issue that we always ran into was Plumbing, the market doesn't really realize just how set up production lines are for glass boats but not so much for aluminum. Ended up going Fraser bronze with marine-grade cast aluminum Weld on through holes. But the first one I installed was in 2009 so no one really knows if it'll last longer than the old options because the issues usually show up between 20 and 30 years that's when they really start Cutting Loose.

Keep the Technical Stuff Coming.

Really enjoy watching construction of aluminum boat. Watching sailing Ran in their construction of a wooden one. ( doing the complete build themselves, a 50 foot from scratch). Both extremely educational. Thank you.

🤔 Both “the devil and excellence are always in the details”. I’ve gained an appreciation of how many details have gone into this design, especially in the area of galvanic isolation. One small question I have is: why did you not just use thick walled aluminum railing components to eliminate the complications of all those isolators? I realize that SS is shiny but all aluminum would blend with the hull and the natural oxide layer could provide grip for both hands and lines. The keel trunk extending below the hull while slightly increasing draft and drag will on the other hand extend the poured lead lower and provide for far easier swing board pinion replacement compared to an all internal hidden arrangement. I admired how the skeg (presumably on DS 3) protected your expensive folding prop from an inadvertent grounding or floating object or line impingement. The twin rudders have no such protection, but then there’s the old drag and balanced rudder considerations. Is your standing rigging (mast & boom) going to be Aluminum or Carbon? Carbon is lighter and stronger but what is its sustainability to surviving lightning ⚡️ strikes? I’m continually intrigued by the many design decisions you’ve made … perfection is never possible but optimization for a particular intent is achievable. Please keep up these detailed videos, they fascinate me. 👍 👏

Great Video. I like how you explain the details. Fun fact: I own an aluminium Yacht myself (Nordsee 49 from Dubbel & Jesse) built in 1991. I can say that - except of the swing keel - 90% of the design features are the same. Drainage using the hull for tanks, separating metlas and so on. Many things are well known and proven to be good. ⛵️ 😊

Very informative re. keeping the dissimilar metals isolated from each other. How often those bushings need to be looked at and/or replaced to make sure they are still doing the job?

What a coincidence. Had just ordered my Tef-gel before the vid. PS: To my horror, I have seen several RVS screws screwed into the "ribs" of the ALU hull. Has it caused corrosion, undoubtedly. Have I taken as much as possible out. Of course. However, the hull is still going very strong. So conclusion, whilst I do my utmost best to prevent corrosion, I also am somewhat comforted that after 40 years of a few glitches my hull still seems solid. Thanks for this really clear vid. As an ALU owner, I love the simple explanation, of a topic so intimidating! (PS: I think the electrics is the biggest issue to be very careful with. I just am about to finish my DC runs, which are in IP44 rubber wire, inside pvc pipes. So triple instead of doubly isolated.)

Thank you for the educational and entertaining update. Our new ( adopted) boat is coming along nicely. We really appreciate your taking the time and trouble to keep us in the loop!

This was very interesting indeed!

I understand the idea behind keeping dissimilar metals from touching and can see how you protected the shaft log/stern tube from the drive shaft touching but was wondering how you isolate the prop from the driveshaft?

Fascinating.

My bet is that the Delrin Moly matrix bushing used is conductive. Perhaps a non conducting bushing would be more appropriate. The Molybdenum Disulphide or graphite black coloured filler makes the Delrin conductive. Perhaps you could use a glass fibre Delrin sleeve bushing. Way more appropriate if the pivot axle is required to be electrically isolated. The enhanced bearing aspect of the Molybdenum Disulphide Delrin matrix sleeve is not required for Improved friction coefficient.

I really enjoyed this video. I wish someday to have a sailboat of my own to take family and friends like you have. Cheers

It is practical to monitor the level of galvanic protection on a vessel afloat using a silver-silver chloride reference cell and an accurate multimeter, together with continuity checks (you want 0 continuity) between isolated materials.

I agree with your isolation of metals, though some are better than others, example my Prop is a feathering stainless steel prop and not bronze and regarding the stanchions, I have a solid aluminum bar turned into a nice stanchions shape bow split & pushpit is an Aluminum tube pipe. A safety line is Dyneema with UV cover. Still, you will find that is not enough protection when in a marina long term due to stray currents. Your boat construction is looking just lovely..

KB would make the CE inspectors job easy. where were the CE inspectors when lagoons were glued together?

Interesting watching your build. Probably the most important piece of information about anodes on the hull which a lot of people aren’t sure about is, should it be bare material to bare material or should there be paint on the hull.

So many sailing channels garnered a solid audience with videos on the construction of their ship. As long as the full boat is in sight (it is beautiful), then of course you should keep them in the menu. At 9:50 there os an odd-welded strip connected to the compression post (near the ceiling). Why is it welded slanted? Is this the correct procedure? Is it strong enough? And what is the reason fir such a weld?

Build looks to be coming along nicely. Good workmanship shows skilled craftsmanship. Am wondering about Maintenance Scheduling… Certainly besides haul cleaning usually every year to few years, an Aluminum Boat requires similar attention. Please explain. And what type of Aluminum is used? Next are wearable and separation/isolation parts, ie bushing, washers, or prefabricated isolation pads. What preventive maintenance plan exists? Considering how Electric Powered everything continues to change designed systems, this surfaces new problems when connecting to Shore Power. Please clarify design schemes. Am looking forward to learning more in future video releases. Marty Didier

I been building ally boats for nearly 20 yrs I’m impressed with the fabrication and design and you won’t have any dramas if you use Tefgel or duralac Lanolin is great for the interior stringers , frames ,bilges ,nuts and bolts etc etc and hidden spots 👍

Interesting idea given how massive/high displacement an aluminum constructed vessel can become and still be both solid/stiff and high performance/maneuverable. Looks perfect for owner operator/de minimus crew'ing

I was curious about 2 questions. In your design decisions.... What was the formula and desire format that she used in determining the amount of fuel you wanted to carry , did it have to do with boat capacity ? or closing style a style? I have a second You're building the boat from scratch , but you really haven't covered any design , To combat lightning strikes ,, Shouldn't you be designimg into the boat , prefabricated something or another , to help ground the boat in the event of a grounding a lightning strike ? Or, to help channel a lightning strike ?

Boat is looking great. Do they do any kind of testing, like dye penetration, on the hull welds to check for cracks introduced during welding?

Based on how much delrin is being used, a mini lathe and a good supply of stock might be a wise investment to fabricate needed parts as they wear out. Speaking of galvanic corrosion, I hear the same is true bonding carbon fiber to aluminum. I’m guessing the same is true with titanium and aluminum. I recall reading somewhere that aluminum boats should use magnesium anodes opposed to zinc. Very interested in how the electrical system will be designed.

It's always amazing to see your episodes, and it's great to see so many details on the progress of your boat construction.

Glad you like them Giampaolo! The lead will be sealed in completely so no saltwater will ever come in contact with it. So as soon as the lead is added the compartment will be welded shut again. This insures there will not be galvanic corrosion since the two metals are not close on the galvanic scale.Yes the next videos will deal with more technical details and updates so we try to stay up to date sharing the build process.

Carbon fiber can cause galvanic corrosion when in contact with aluminum through a redox reaction. Carbon fiber can be used for the mast, boom, stanchions etc. if you want to save weight but the material has to be isolated from coming into contact with aluminum. This can be done by coating the carbon fiber with a layer of fiberglass because it has no conductive property.

Excellent question, Marc. The boat is insulated to the waterline so the hull below that is inspectable.

Is Zinc the correct galvanic protection for aluminium.... Google gives this. Does aluminum corrode with zinc? Galvanic corrosion occurs when metals break down each other. If the aluminium comes into contact with a more noble metal (such as copper, zinc and certain types of steel), aluminium will be broken down.

Lead melts at 621 F (327 C) Aluminum at 1218 F so it wouldn't melt it. However it might warp the alu so its super important to keep the alu cool. So... when the lead was being poured the hull was dipped in the water to use natural cooling :-) Sadly we weren't there to see this process! Regarding stanchions - its partly that stainless stanchions are more user friendly. brushing past aluminum and holding it you tend to get a gray oxide on your hands.
