Taking a gamble on our sailing yacht build! I really NEED this to work!
Рет қаралды 23,351
13 күн бұрынThe first job on our new build yacht project and we were left with no choice other than to try using an iPhone 15 Pro to scan a very unique keel for this aluminium lift keel yacht!
With only two other boats like ours in the world, we tracked one down to Scotland and had 1hr to scan her keel in order to make our own mould. The pressure was on as this was a one hit wonder…
We share our findings using 3D scanning app Polycam, show the differences we found between LiDAR and Photogrammetry along with a helpful tip we got from the pros.

Not a bad idea mate. Lazy way weve done it, get a box cover the bulb and fill with expansion foam. Then cut in half and have a full mould. Just remember to cover in cling wrap or release agent. This has proven to work well in our yard for moulds that are straight copies from sister ships.

For sure, that would have been ace. Bug with 1 hour in the slings I wasn’t confident enough to use up my only chance with foam due to the hardening time.

Two videos into this build and I am looking forward to seeing what a pro wooden boat builder can do with an aluminum hull. Great find - I'm usually not a fan of aluminum boats but this one looks to have great lines both in the hull and the cabin top. The lifting keel looks pretty cool too - more maintenance but more fast. With Tally Ho going in the water, now I know where I can get my quality boat building video fix. Thanks for sharing!!!

LiDAR is good because you get actual size models and is invaluable for that reason. There's also the ability to add different models and merge them to make one that is more accurate - I'm not saying it's the best option, just find that if you don't have the tape measure or don't have the time to go over every single detail the LiDAR + photogrammetry combo is unbeatable. Basically make sure you have the same sizes between them :) I love Polycam, early adopter from 2020. It'd be great if there was a free Rhino alternative for the right kind of geometry but we can't win everything!
@SailHub 9 күн бұрын
Yeah, your right! We can’t win everything!! We found the scanning really interesting and the results even more so. At present we are crunching the numbers and deciding on what’s the best option but we now have options which is a step ahead for sure!!

Great project btw.😀👍⛵️

adding to my comment about placidity city, the other advantage of using plasticity is it can produce “watertight “models, which are necessary for 3-D printing. The idea of being that you could 3-D print a positive version of the keel and bulb, and then use that as thebasis to build a negative mold. That could either be for layup, or I suppose you could cast directly into it if you made it out of plaster or something similar. Perhaps even sand.

I'm using it for a boat project, so I wouldn't mind seeing what I might learn.... in case you wanna talk about it, lmk. That's with regard to the computer stuff: the fabrication is another thing, but having cleaner data is never a bad thing.

You know what the best part is of a displacement keel is you can figure out the best hydro for it by tank testing so lead takes up space for the amount of weight also means how much space it must take in our world this is called mass so yeah sure take some ideas from their keel water test their keel and refine it and play with making it your own for better hydro anything is possible their design might have drag in certain places can make better or you duplicate it and make things easy I build and rebuild boats for a living my keel on my racing sailboat is a full keel weight is 4 and a 1/2 tons of iron full boat displacement is 18,000 lbs usually for a builder and designer 50/50 between keel and construction weight with mast and rig so add it up
@SailHub 4 күн бұрын
Hey Graham, thanks for the input, we’re looking into bulb shapes and also the reality of the beaver tail actually creating any lift. But, we’re running out of time and money too so we will see what we get. I wasn’t planning on tank testing as I know it is. Pretty successful design and I’m not sure the costs of tank testing will be warranted. I would certainly love to do it though! As for weights, we’re looking at 2t, existing hull and mast weigh around 3.5T I’m told however that is just what I’ve been told. As we’re on a farm it’s not so easy to get her weighed although there is always a method, just not sure if I need to make a cradle. Anyhow, plenty to think about! I may push for some prices for some tank testing… 👍 Cheers!
@henripettersson8912 8 күн бұрын
Have you tried to talk with km? Usualy they keep their designs at least as a reference. For Standard parts as the bulb in a komplex Lifting mechanik i can Imagine they dont change it much at all. Of cause they scale it though. I would try to get in touch with them anyway because they will certainly have the weight calculations and everything you might need aswell. And i guess they dont want to see a couple on KZfaq doing it wrong and end up with a "km" hull with poor Performance. Interessiert approach though. It will probably work just fine!!
@SailHub 8 күн бұрын
Hey up Henri! Yeah, we know the guys at KM, we’ve met a few times in person and spoken a lot too. Really nice people. We have all the drawings and everything they had for the design from them and also everything form the cutting company they use too - Gaastmeer. Sadly they don’t cast their own lead and the company they use no longer have the drawings. So that’s where we are, but it was good of them to help us with what they could. As for them worrying about a couple on KZfaq, I don’t think they are bothered at all, we all know the quality of their build and I’m sure they will be more than happy with the quality of ours too, however I don’t think they would care either way to be honest.

Oh they will… but up until now only if they complete the full works. So far the only quotes that came back were for the wrong boat and £16k! Then there was the quote for the correct keel (if I could get the drawings). That came in at 45k! Sadly that’s out of our budget.

Yeah, that’s a good idea and we thought of similar but figured out 1 hour timeframe was pushing it too fine for us? The main issue I had for seen was drying the boat down. Unfortunately all of the water on the thing and from inside the lift keel mechanism too runs to the bottom which is where we needed to be… not ideal! The first 1/2 hour was taken up by this drying process and it still wasn’t great. Most likely causing reflection and why the early scans were poor. As it turns out, the guys were super kind and we could had longer and your idea would have been fab! But, could you bank on that and the Scottish weather?!
