Like the title said, is ther much difference in speed between the two, same power. 2,5 efi for example.
I dont find much to read about them.

There is only one DW "30".

I think I heard somewhere that Doug said on the 32 he just built the same boat on a larger scale. But I have no idea.

I know the 30 has nothing for a 32 in BIG water.

My 30 with 280s race set up with 31s ran 117mph. I believe on top end both are very fast and nearly equal, but in a race the 32 will always top the 30.
