Thread: Black Swan

Your work looks quite good. Why would you use such heavy and dense species for a stripper canoe? Typically, most would employ WRC, which is 33 lbs. per cubic foot (535 kg per cubic meter) or other equally light species, while your choices are considerably heavier. Did you reduce strip scantlings to compensate for strength, stiffness and weight differences? I'm sure this combination will be pretty when varnished up, but how much does it weigh?

Can you to use any wood. And those types of wood that are not sufficiently resistant to water, because once coated with epoxy resin, wood is no longer "works" and does not come into contact with water. I use strips of mahogany and walnut, just because of the beauty and just because I managed to find you a good price. The total weight of the hull 17 feet long no more than 15 pounds. I have not finished all the work around the trunk because I had problems with the place. I did this on the deserted courtyard behind the building, but how are people envious, we have started to cause problems, so I moved it all to a safer place.

That looks fantastic.

A mahogany stripper kayak, that's 15 pounds and all the rest of use have been doing it with the much lighter WRC for heavier. You must be a designer/craftsman/magician. Frankly, I'd be surprised if it wasn't twice that, possibly more. What's the length of the kayak and the dimension of the strips, because if you're building a typical small size kayak, say 16' (4.9 m) long, with a 20" (50.8 cm) beam, with say 40 - 42 sq, ft. of surface area (~15.5 sq. ft. water plane), you'll be decidedly heavier (twice as much IMO), with a 4 ounce sheath over WRC strips. You could make a small fortune selling plans for this 15 pound, mahogany and walnut stripped boat.

I'm not trying to insult you, but really, 15 pounds? Maybe you mean kg's?

Do not worry, you have not insulted anyone. I'm not going to convince anyone. I do not earn my money to print the topic. I do it because I like doing it, but I'm not going to argue. (Indefatigable, my kayak called the Black Swan, just difficulty setting to make it clear to people that it's a common thing for me, even so I designed one and built reeds). I do not give a damn if you weigh 15 kilograms or pounds, or tons. thanks

I'm intrested in your strip spec's on this build, simply because at 15 pounds, using a couple of strip species that are 30% - 40% heavier then what's normally used, yet producing a kayak at half the weight is revolutionary and should be explored. Maybe you don't care about the weight of your beautiful build, but there are lots of canoe and kayak builders here (and elsewhere) that would love to be able to build a 15 pound boat. So, if you can, would you share the physical dimentions of that lovely kayak you've built, along with is sheathing schedule, strip dimentions, etc., we'd be forever in your debt.

I said that I have not finished building. So, the frame and inside, it weighs a lot because of MDF, I have not taken off. The strips of mahogany and walnut are thin are only 6 mm. I physically do not have weighed everything, but moving kayak, I noticed that frame does not weigh more than 35 kilos. By removing the frame, should weigh no more than 20 kilos (15 kilos and maybe a bit exaggerated, I consider ourselves). I'm sorry that we talked about the things that do not matter to me. I made another two-seater kayak, that 21 feet long and weighing 27 kilos. I just wanted to show that the construction is not as demanding that doable with a bit of crafts and just a few tools. Meanwhile, I'm sorry if I was a bit rude to you. Thank

Hi Zoki
A beautiful looking boat.
It is maybe a little sad that only "heavy" wood species are available to you.
Light weight timbers make a kayak soooo much easier to lift on/off the car roof.
But such beautiful lines and timber look.
Well done !!

If I had a lot of "heavy" wooden slats do not think that you would not do the same thing.? I bought almost two miles of strips of walnut and mahogany, and that not until I get them out I do not stop to build heavy wood. In fact, I've done other items such as my subwoofer in these strips.

Very nice build Zoki, looks like it will be fast on the water. What design software did you use?

Thank you. I used K-foundry. This is a free program

2 miles of walnut & mahogany ! Wow !
Both incredibly expensive here in AU.
The sub woofer looks good too.

And rightly so much stuff, but as my salesman closed timber, made me a very advantageous offer.
Strips are 70% of walnut, 20% of mahogany, and oak, and more. There are 6 mm thick and 5cm wide, various lengths from 3m to 5m.
