awesome to see your daughter come on aboard to help you out definitely can't refuse that kind of help now can ya.

A fine welcome home, put her straight to work. Another great episode documenting the boat that would have been done a year ago if you hadn't been documenting the build on video. Thanks for all your efforts taking us along. Stay safe

I do see rudders needing to be replaced after hitting something. The rudder is not usually the concern. Its the rudder housing being forced and cracking the hull open. This is why so many are going with break away rudders. They only need to replace a pin and sometimes small fiberglass work on rudder. Making the rudder housing inside each hull strong enough to withstand a hit is key with fixed rudders like yours.

So great the family are eager to get this tub in the water. So mum and dad can finally enjoy their retirement 🤙🏼🤙🏼🤙🏼🇦🇺

First, your daughter has beauty, brains, and a healthy devotion to family, as all your kids have, making you and your wife winners in the gene pool. Second, you and your family have worked hard to create a Shipshape and Bristol fashion vessel and I'm sure it will be Yar. I can't wait to see the video of the splash.

Hi Rossco and Janice, I think personally having a space rudder is a must of watched a lot of programs with yachts and catamarans around the world, and that seems to be one of the major problems keep up the good work. Love the videos from Queensland

Love it Ash.

I wonder how that's gonna affect rudder performance. The longer tail does have a reason there. Oh well, should you find it insufficient, it's easily modifiable even after she's in the water.

The dam at the front of the seat is what I was trying to suggest you do in the hatches in the sugar scoops some months ago, the thin strip that is about 7 cm high that fills the gaps at the front between the Chanel’s. With a little effort it would also help support the front edge of the hatch. But up to you. You have a great family. Some pretty amazing timber work in your previous episodes, but the whole boat is looking amazing.

Really coming along !

I always plan to have 2 spares. One to replace a broken item, and that leaves another spare while you restock. But in your case you have 2 rudders, so that would mean 4 spares, that seems a bit OTT, 2 would probably still be enough.

I would put a stainless steel bar in front of the rudder, that way the ground will hit that first and save the rudder. I believe some cats do that as Standered.

I should be sleeping... but there is new video from Life on the Hulls. The rudders look great. Does it impact maneuverability, that you cut them shorter?

Shouldn't be a big stress losing a rudder, most catamarans will sail quite well with just one rudder.

@LifeOnTheHulls

4 ай бұрын

I reckon we will be all right, can always steer with motors for a bit.

I think the surface area of that ruddy will be lacking, but I guess on the testing part in the water if you find that to be the case you can make a bigger one easerly. I would make the riddance wider rather than deeper, that way less likly to ground it but more surface area to channel the water. But than I do not no anything about cat rudders.

Make it strong, don't want the Orcas biting it off!

@LifeOnTheHulls

4 ай бұрын

It did cross my mind mate.

If I were you, I would move your template back 80mm to compensate for the lower surface area you removed. That should restore the steering authority without needing to deepen it. You may lose some stearing if you are sailing with a hull slightly out of the water though.

Good point. Also thought a radius on the front may help with any obstacles. We better not suggest improvements now the rudders are already made.

Winglets on the bottom will also work.

Tip...! Cut a 20- 30 degree angle aft and on top of the rudder behind the shaft, if you hit something and the shaft bends you still have steering since the rudder will not jam and will not punch a hole in the bottom as easy :-)

@SVPearler

4 ай бұрын

But that then reduces rudder efficiency, you want rudder to be as close as possible to the hull. With a cat, you have two engines. So you still have steering, been there done that!!😮 I bumped a bommie. Lucky for me, it was not too hard to fix myself.

14:33 best to have and not need than need and not have. And if you're setup, you already have gone the extra mile for it. Also, kayaks aren't comparable with boats. Forces are greater. So a rudder on a boat is far more easier to break from the lightest of touches, whereas on a kayak, you scrap it a bit it will bounce back. 18:45 well, we know who she took after. :)) You got yourself a great kid.

Gidday Frederic.Carbon shafts were made to order by Kilwell Fubretube in Rotarua NZ.My contact was Wade , I think.They engineered them to 6mm tube with unidirectional and double bias to their suggested spec. They were so easy to deal with but order miles ahead as they supply most racing competitive yachts including Americas cup and Sail GP.Cheers Ross

I’m sure there’s something I missed but aren’t you concerned about cutting off that much of the rudder below the keel line where it’s most effective?

@LifeOnTheHulls

4 ай бұрын

Not overly concerned as these are larger than the original rudders designed for this hull. We have a unique hull as the skeg funnels water directly on to the rudder so in effect laminar flow should be uninterrupted. Time will tell, I can always add a sacrificial bottom onto them should they not perform well, but I have a few friends that have shortened theirs to good effect. Rossco

@@LifeOnTheHulls definitely not dull!!!

Love the show and always look forward to your jovial attitude and can do spirit but taking away 15% of your rudders surface area without compensating in any way is a terrible idea! If you lengthen the cord which is the minimum you should do it will create weather helm. To save a few inches in draft leads to all sorts of consequences including inadequate steerage under sail, weather helm and drag. I hope you reconsider.

I like the idea of a bullet proof rudder and appreciate the build design. Please don't take this as an insult. I think that there is a few problems with your planning. A chain breaks at its weakest link, by making your rudder bullet proof, if you do hit anything with your rudder that extra load is now transferred to the hull and can damage the thru hull area. I have witnessed this effect with the making of a 60ft Crowther's dagger boards. They were built strong by Professional boatbuilders, all's well and good until vessel hit a sandbank at 8-9kts. Dagger board was not damaged but split the casing in the hull, causing significant hull damage and vessel having to be lifted for repairs, at great cost. If when making those dagger boards the builders had designed weak spots on the lower parts of the boards, they would break off, a sacrificial offering to the reef Gods, without causing hull damage. What are your thoughts please??

@LifeOnTheHulls

Thanks for your comment. I appreciate that a failure point is worth building in to the rudder, hence the reduction size as it would have protruded about 20cm below the keel line so am banking on the hull taking the impact and not the rudder , however the carbon shaft will likely crack in the event of a collision and the rear rudder compartments are totally sealed for the remainder of the boat, in effect a failsafe has been considered. I may well add a sacrificial bottom on the rudders if they are not long enough in the end. Sad story about the crowther mate, would have been seriously expensive to rectify. Cheers Ross.

Foils are tabbed and epoxied to shaft to form tynes, foam then glues and shaped to foil shapes.

Rudders blades are made with vinylester resin.Tynes and foam will be adhered with epoxy, then back to vinylester for outer laminates, then epoxy barrier coat prior to anti foul.

Great work, you are making progress in leaps and bounds and you now have another pair of hands even if they do come with conditions attached. It makes a great deal of sense to make a spare rudder while you have the wherewithal at hand. In fact I think you should fabricate to a finished state completely, there are so many YT videos of having to make a new rudder it is not the rare event we would like to believe - and that’s not including the casualties arising from Orcas who have discovered a new sport. Keep up the good work.😀👍⛵️

I thought this through and have a few friends that have done this with this design with little real effect. The original rudder design for this boat was much smaller, this one is larger than it and will be far more efficient in spade form. Cheers Ross

The carbon is pointless here it just adds cost -as weight is not an issue and eglass would be fine

Can you explain the reason for the mix of CF with E-glass doesn't this seem counter productive. Are you essentially using the glass as a core instead of foam?

@LifeOnTheHulls

Centre spine is the carbon ,eglass lsminate,foil stations are the same material, then infill with h80 foam (not 2 part )and shape to foil, laminate over the whole deal , barrier coat and anti foul. Leading and trsmailing edge double thickness laminate to withstand minor knocks without breaching edges and nil caoacity fir water absorption as with other blade techniques.Carbon ia just a stiffener in the vertical plane nothing else.Carbon shaft is to eliminate corrosion issues.Ross
