It will end up under 50 kg but not that much. I have very little experience in foam building and the foam is eating a lot of epoxy...

Try brushing on a layer and letting it kick before putting on the actual laminate. Or wetout and squeeggee your cloth off the part and then lay it on, the foam shouldn't wick resin out of the glass if you have the right amount there.

Do you know how much resin you used on the DS?

Squeegee a thin bog of honey consistency on the foam right before glassing. No need to let it cure, glass straight onto the wet bog. This will require "half" as much resin.

Thanks for the advises!!! The epoxy for the DS12, yes I have it written somewhere, will try to find it when I get back to the workshop.

The filler works,using peelply helps with weight to (shower curtain nylon works well)bill

The 4 halves are joined together, now it's up to the Nice Lady if we get some pics...

Gato, do you ever sleep ? <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />
As this is actually a retorical question, judging by your activity - then the most interesting question is: how do you do it ?
Now seriously, great work !!!

How do you find working with foam compared to wood/plywood ?

The trick is; A bad carpenter has to cut a plank 3 times before it's to short, a good one does it at once...
Working with foam is great, fast, giving a good result and the cost is about the same. In fact for the moment I don't see the reason why to work with ply.

You can not enjoy the smell of wood, and the pleasure of using your plane with foam <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />

Can you buy sheets of foam, or do you have to buy a whole package.

Well, the okume ply dosen't smell so good, it would be different if you built a real wooden boat.
As for the foam, you can buy a single sheet. I will try to get some pics for Monday.

Great stuff!!!!!!!

Almost looks like strip plank boats. Interesting shape to the hulls!

I would be very interested in hearing how you did the join of the two halves. Bulkheads inside etc.

Don’t know if I shall recommend the way I joined the halves, at least not before I have smashed the cat into a big wave... The good way is with flanges, but I wanted to go fast...

Usually the worst loads are beaching and trailing, not necessarily sailing.

I know Farrier designed home-built hull halves are never flanged. They do have some tape applied though... I guess you did that too. Never heard of any problems with those.

I did a small rebate and added some extra glass BX+/-45deg over the joint. I’m not really scared of it breaking. The two hulls are glassed and I will try to get the time to make the beams and landings for them the next weekend.

So here we are, a new cat in the water. It’s not painted yet, just a little bit of primer, and the rig is borrowed from the DS12, but I could not resist. There was not a lot of wind so it’s still hard to say anything about how it’s sailing, but even with this light wind it was easy to tack.

WOOHOO!

Gato, congratulations! You are amazing. I want to grow up and be like you <img src="http://www.catsailor.com/forums/images/graemlins/wink.gif" alt="" />

Tested the new boat on the kids yet?

Have you weighted the complete boat yet? What would the weight difference be between the two boats?
I was wondering how it would be to cartop these on a regular sedan, nothing else.
