Re: Let's be silly or maybe not!

looking at a LBS/HP ratio of 2.5ton per 850hp, I'll open the betting at 60mph.
if you say 2500rpm then I'll bet 39 pitch is over pitch by 14 inches

Re: Let's be silly or maybe not!

you must define available horsepower to get speed.
speed is a function of HP vs weight

Re: Let's be silly or maybe not!

as boat size goes up, shaft rpm does not go up as in smaller boats. at least not unless you are going 100mph. Example: the mahogany's at the G might turn a 13x13 and run 30mph with a V8 1:1 gear A big sportfisherman might be 45', run a honkin' diesel with a reduction gear, and turn a 30x30 prop. and...

Re: Neel's Palm Beach 22 build

I also used the back-to-back carbon paper for my half patterns, and I went another step; I got the heavy roll of paper from Home Depot, I think it is used under flooring, almost heavy as card stock. Anyway, I got the carbon paper lines onto the heavy paper, so now I got a full set of my plans, full ...

Re: Neel's Palm Beach 22 build

Neel, do you use the pumps for your jugs of epoxy? I do, and graduated the hardener pump stroke with a sharpie marker. Say, if my ratio is 3:1, I marked the hardener pump in 3 increments; this allows me to mix the resin in quantity of 1, 2, or 3 pump strokes. If I wanted a quantity of 4 resin stroke...

Re: Console Skiff, Fiberglass or not?

the fiberglass skin adds so much abrasion resistance, that I vote that you need it.

the plans might say you don't need it for structural integrity, I agree,
but for abrasion resistance, I would not go without it.

The first one spec EN 13986, I do not know

Which spec is applying to the ply in question?

Re: In hull Transducers

" Yes, there are flush mounted thru hull transducers. Correct, they won't hang up on anything. They can be damaged by beaching though. Try beaching and having the transducer sit on that one rock at just the right angle. Think that can't happen? Ask my cousin. Is it going to happen everytime? No...

Re: Stretching out the beam?

Most of the designs on this website can be stretched (or shortened) in length, but not beam.
The Parker looks like a Lobster or down easter. Is that so?
The nor'wester is a full planing deep-vee.

Do you want a lobster running bottom, or a deep vee?
