I currently have a Destroyer and had an Assault. Believe me when I tell you from practical experience that the destroyer is considerably more "deep V".
The ride on the Assault is awful compared to it.
I always assumed the sponson extensions are for two reasons, to protect the outboard when on the water and backing into a garage and also to make the bow stay down, again for inexperienced cox's.
The difference in on water handling is also marked. An Assault will skip sideways flat on hard turns as not enough hull is in contact with the water. Destroyers will lean in and turn 180 degrees at 30knots within two boat lengths, or at least mine will
Other deep hulls will do this just as well or better.
The story of how I ended up buying an Assault has been recounted on here before but basically I ordered it by phone due to my location. I asked if it was the replacement model for the Attaque and when told it was I ordered it. When I turned up at the factory I was horrified to find what it actually was but by then it was too late. It was the replacement in their "model range" for the Attaque but was nothing like it in form.
Right question but not the right answer and from the day I bought it I was planning to replace it.
The Assault is really a cheap small rib for pottering around on lakes, inshore and for sailing club safety boat use where it won't be exposed to much rough weather. It is cheap, fits in a garage and it easily handled.
