Just wondering

Post by Aaron M »

Why do decked wildwater boats have that volume bulge in the back?
I assume it has some purpose for performance, but how does it help?
I saw a duck skirt a hole and then eddy out. He could have easily flown. Makes you wonder, why'd he do that?

More knowledgable folks will hopefully weigh in on this, but as far as I know it has to do with the minimum boat width that is allowed - and as the boat is wider, you have a bulge to the sides...and to keep a boat light (thin layup) you need a curved surface (or ribs, but they add weight) to keep it structurally strong...so you get the "bulge" upward as well.

You'll see similar designs in flatwater OC boats...though without the decks, of course.

Boat design always has constraints...sometimes imposed by regulatory bodies (for race boats), sometimes by human abilities and physics...not that the boundaries of both doen't get pushed occasionally :wink:
Keep the C!
