[quote=Walter]Here is my Catamaran Dream or some might call it a halucination. LOL
If we could just get the basic CC hull desiged, something close to this:
Do you have any experience how this boat will handle chop? The flat part between hulls look very low (Like in the GlenL -design);
INSERT INTO phpbb_posts (old_post_id, topic_id, forum_id, poster_id, post_time, poster_ip, post_username, post_subject, post_text, enable_bbcode, enable_smilies, enable_sig) VALUES and it will surely hit the waves. The "tunnel" is quite high in bow, so the flat -part has low angle - that must help.
So, would a cat like this really be better in chop that usual monohull?
[quote]If possible the basic Catamaran could be offered with the option of Planing, Displacement or Semi-Displacement Hulls. Depending on the builders desires.[/quote]
But will the compromise be too big? It might be bad in all these.
Efficiency is all about hull shapes. A catamaran will be less efficient if the monohull is scaled to half width and two of these hulls would make a boat. Those figures look a bit marketing values, but they might be true. Just remember they are for 46 footer cat. As said before the cat's will be nice when they get big.

Why would this be a problem?
Actually the displacement will not be reduced so much, the cat's just have bigger draft.

And two motors will be less efficient, require twice maintenance, maybe two gas tanks, two for many things.
But the biggest problem I see with small cat is how to make them efficient and practical. Another thing is to keep the cost and bulding time reasonable.
About the contest;
While it's fun to judge the designs, I must say I can't see how the boat will behave from the hull shape.
Like Jacques thinks about hull shape here;
So, maybe could we get someone professional to give their input too. i mean I would not build a boat without a pro saying it's ok.
