23 powercat plan

Hello I'm french so sorry my bad english. I want to build a 7 or 8 metre (23') powercat plywood and fiberglass (not alloy). I'm looking for a similar plan to Bruce Harris' shark cat (or Famous Australian Noosacat style). I have already seen a lot of plan on the web (glen.l, skooda ...) and my choice is on the stormcat 23 but the plan is a bit old. I was wondering if there were other plans similar to stormcat 23, maybe newer or powercat designers that I could contact. Thank's for your help

 

Nothing for plywood that I know of, that is new on the scene. Here is a similar discussion...….
Cat Build (power) https://www.boatdesign.net/threads/cat-build-power.59336/

 

Spirited Designs has a balsa kit, might be worth looking at. I think if I remember correctly the plans will work for ply as well, reach out to them and confirm that: Sailing Catamaran Kits | Sailing Construction Plans | Spirited 230 https://www.spiriteddesigns.com.au/spirited_230

 

Might be better off shipping an old Sharkie out there, there was a bloke sending a few second hand ones out to Vanuatu. Unless you are wanting room for a lot of people, the more common 18 footer (560) will do the same job, with aplomb. Trouble is they are getting long in the tooth.

 

Thank you for your answers. I had already seen the boatdesign forum on the stormcat / wildcat / skoda .... and also the spirit but my preference is stormcat. Here is 3 pictures of the stormcat but aluminium version. He looks great.






Si I have some questions about building

 

First : as the wildcat (glen-L), there is a cushion of air compressed within the tunnel that adds to lift for quick acceleration while softening the ride. Can I remove this air cushion and therefore the holes in the bulkheads can be removed in order to make watertight partitions for more security in case of waterway (I hope I'm clear because of my very bad english).

 

That "cushion" is a reference to compression of air within the tunnel, nothing to do with the internal structure of the boat. Having now seen the pics of the Stormcat, I'd say it looks OK to me, if it can be made in plate, it could be adapted to ply construction if needed.

 

Ok, so do you know why are there Holes in the wildcat bulkeads please ?

 

Saving some weight, improving air circulation perhaps, Your best plan for flotation would be to fit blocks of polystyrene foam during the build, not use pour form.

 

thank you

 

Certainly think the Stormcat is the right shape for the job, It is similar to the 23 Sharkcat, but without the flat along the demi-hull centrelines, which was probably designed that way to drive on and off the trailer easily, as much as anything else.

 

I looked at the ads after seeing your post and man, are used cats sure expensive in Au

 

Aluminum cats are very expensive to build. The material, labor and equipment you use is expensive and there are 100's of feet of welds that have to be done on both sides. It took 2 years for 2 guys to do a 28 working almost every afternoon, and that came cnc cut ready to weld.

 

GOOD MORNING I AM FROM BRAZIL, I BUY THE POWERCAT CONSTRUCTION PLANS SAME JANO MODEL THE COMPANY HAS NOT GIVEN ME MORE IMFORMATION I DO NOT KNOW HOW TO BUILD ANYONE CAN HELP MY EMAIL bekocarvalho43@gmail.com

You should start your own thread rather than hi-jacking fano's. It is very bad manners to do this. Also, writing in all upper-case letters means that you are screaming at us; also seen as bad manners. You can contact the moderator to move your post to a new thread.
