NIce to have you on board here Arjan. I've been following your build for a few years. Congratulations on a fantastic job!

Could you post some weight and performance figures? I would imagine she sails as well as she looks. There are many posts here asking about performance, and many settle for the condomoran level, and don't know what they could get

Couls you tell us where you got the mast design from?

RotKat weighed 15000 lbs when launched this was with almost empty tanks. I have made it a point to keep the weight off every chance I get and I would think that she is 15.500 at the most.
When I was ready to launch I was also completely sick of bleeding money so I decided to buy an used main and use that for a year or two. with that main and a 20 knot breeze she would do about 17 knots tops with long periods of 10-12 now with the new two week old Dave Calvert main I hit 19.5 knots on the first day out, it was probably blowing around 30 knots and I "forgot" to reef but when we were going that fast I was de-powering the main big time. Last weekend on the way back from a trip to Vallejo I reefed the main before getting to the "slot" where we maxed out at 18.6 knots with the aparent wind in the low 30's, again de-powering quite a bit. I think that I should be able to get well over 20 knots as soon as I have the guts to go and push a little harder.
With the dagger boards and the new main I can point almost as high as the monohulls and even in lighter air she does well.

Sounds like a great boat to sail, thanks for the input Arjan.

I am interested in the mast design, could you tell me who did it for you? It looks great. How big is the chord compared to the boom length? Also any details on your rotator controls would be nice to see . I'm looking for inspiration/ideas here...

Good to see you here Arjan. We corresponded a bit on the Yahoo electric boat forum. By sharing your experiences with the electric propulsion you saved me a ton of time and loot. Thanks again and congratulations on the beautifull boat.

My first post so be kind to me fellas . My reason for responding to this thread was that I am contemplating a Gary Lidgard design to retire on in about 5 years.

Whilst not set in stone I'm contemplating his forward cockpit 50 footer. Not terribly unlike a gunboat 48.

If mine turns out 1/2 as nice as ROTCAT I'll be one happy camper. Congrats Arjan, I'm sure Lidgard would be pleased with your rendition of his design.
