There's a lot of 'toon manufacturers out there, I know, and I've been
looking at all their propaganda about why there's is the best. Granted
I'm not looing for a "new" pontoon boat, but the used market is fine
with me.

I've been studying the advantages of every 'toon design ie round, U-
shaped, square etc, but have always wondered why s lot of mfg's will
cut the back of the tube off right about where the engine mounts,
while some will have a pointed tip which my or may not exted back
beyond the transom.

I would think that an extended tip would be more efficient for
"gliding" though the water and provide more bouyncy. (I know, bad
spelling!)

is there any advantage to a rear tipped tube? over a squared off one?

I can almost understand the advantage of a U shaped tup over a round
one, due to the fact that loading heavy over towards the transom can
cause the rear of the tube to "sink" above the curvature of the tube
itself,, but then again, I'm not sure if thats a good/bad factor or
not.

I've seen some tubes that were hollow iar, and some that were
styrofoam filled. the filled tubes sound more attractive in case
there's some puncture, but otherwise I can go either way, I suppose.

I'm really looking for a 26-28 ft float, if that makes any difference.

Oh yeah, Not STEEL!

Looking for ideas.

THANKS!
