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.

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.

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?
