22-24 feet power catamaran

little update. i know its been a while. my mate has done a quick 3d drawing which he printed of for me. i have got to get him to make some small modifications to the final drawing. i will have more pics soon on a disc so will be able to upload proper pics ok.

what do you think of it so far.

 

The hulls look asymetrical so there could some crusing affects that you should look into. My work barge has 30 inch diameter asymetrical pontoons with narrow centered bows. While cruising at 12-mph, the water level between the toons is 10-inches higher than on the outboard sides. The faster catamaran power boats have vertical sides on the interior. There may be a difference in efficientcy with different hul shapes and speed.

 

Sponsons look symmetrical to me, from that pic. That seems to be the accepted norm for all round usage, I don't think he wants a speed demon.

 

not after doing 50knots. if it will do 30knots i'll be chuffed to bits. cruise at around 22knots. both hulls are identical. i have got to make a couple adjustments to the final drawing yet. hopefully will have finished hull drawings done soon. as soon as i get them on a disc i'll upload them on here.

 

Hard to tell from that view, but my first impression was the bows are a bit too full, going on what I have seen in proven vessels, I'd have probably gone for a deeper vee with a triangular pad at least 9 " wide at the transom, and sharper bows, but what you have seems workable.
