.......and in reply I say!:

Thanks for all the posts guys. Nick I've tried to follow up several
times but it didn't work, so I had to sign up under a different
address just to post this.

OK. Thanks. Posts with no follow-up are a regular irritating feature
here.

Planing hulls and power are not my area. But IIRC power cats actually
take MORE power per performamce than planing monos. They ride better,
and handle the rough stuff, but are not as efficient. I would imagine
more power is needed to get on plane, and the wetted area would be
greater.

Planing tris are stable and have good load-carrying, but have a rep
for pounding in chop. You have not said where you will use this
beasty.



After alot of research I realize I need a planing catamaran or
trimaran hull as you all have told me.

I've found several boats on the net that come close to the performance
and hp I'm looking for. But not the style. As mentioned in the 1st
post I want to build a platform/deck type boat. Something that would
haul 5-6 adults and cruise at about 15-20 knots with a top end of
20-25 knots with the lowest hp possible. The websites listed below
come close in size and performance.

I'm leaning toward a 14'-16' planing trimaran hull. Built as a
deck/platform boat. My hope is a dry weight of around 600 lbs. and
full load of around 1800-1900 lbs. with a 35-50hp two stroke outboard.
I know that a I'm asking for alot but according to my research these
type of boat out perform any other boat type out there for low hp,
high payload and low fuel consumption.

5-6 people at 25 knots in a 14' boat....hmmm...very flat water please,
and watch out for the other boats' washes.


I still don't know if my ideas will work. I found formulas and charts
to help determine the top speed of monohull planing boat, but the
multihulls seem to outperform these figures by a long shot.

So far this is all I have. If you have anymore questions or comments
please email me or post them. Thanks again for all the suggestions.

P.S. Can you guys tell me how to embed html into my posts? I wanted to
hyperlink the websites above so you guys could check them out and come
right back but was unable to.

NO! HTML in posts is a PITA to most people.
- Heaps of useless fat, and my newsreader can't deal with it anyway.

- This does not worry me as html allows bugaboos in there.
- although I have set up for "open in new window" half the time if I
click a hyperlink, I lose whatever I have up in my browser, because it
uses the same one to go to the new link.

I would rather copy and paste the site into my browser. Takes one
second.
