29,32,35 H&H Osmond Beals ????????

[BillD]

I have a question on the propeller szies for these boats.

Reading the spec sheets on the H&H website...........

The 29 can swing "up to" a 28" wheel

The 32 "up to" a 26" wheel

The 35 "up to" a 26" wheel

My question is...."why the bigger wheel capability on the 29 vs the two bigger hulls" ?

The reason is due to hull design. Shallow draft verse deep draft. The larger wheel provides better effiency of the power train.

Agreed

So I guess the 29 with a QSB 380 or 440 will have cruise capabilities in decent sea conditions to cruise at 22-23 knots??
Yes????
Opinions??

There are more factors including hull speed that have to be concidered when estimating speed. H&H could give you an idea about what to expect.
I'm sure 29 owners would tell you what they have and what the performance is.

Already checking with both,
Thanks, Bill

I've got a 24x26 on my 29', i'm thinking these shots were taken when it was first built. Anyone have any idea where or what marina this might have been in?
