Has Any Performance Boat Had Greater Than 24* Deadrise?
 

24* seems to be the standard for go-fast vee boats both big and small. Has anyone tried a steeper vee? Does it make a boat inherently unstable?

One word: SUTPHEN.
Nuff said.

In Australia we had a Fastlane 40' built from '86-mid 90's. Not much info available now but I believe they were a 26 degree dead rise. Big boat, wave crusher but not very fast. Most of them had 454's @365hp and the factory claimed 60mph but in reality, it was closer to 50mph. I'd heard one was built with V-12 Lamborghini power and did 70mph.

They also built a 32' version that did 70 with the twin 365's and it looked the same and was a great boat to drive. Not sure of the deadrise on the 32.

I was out one rough day in Port Phillip Bay on a 40 and some friends in a Bertram 35' flybridge were alongside us. At about 28knots, the Bertie was flat out and riding a bit bumpy and wet but the Fastlane was slicing through the chop and we stayed dry. Still pretty good at rest but it was 9'5" beam.

One of my favorite Aussie boats, lousy pic from google attached.

Sutphen
 

That says it all !!!!!!!!

Pretty sure some Sonics had 25*

Though not a traditional "performance boat" of the closed-deck V-bottom or catamaran kind, the MTI V-42 has a 26 degree deadrise at transom.

OK, interesting. What deadrise has Sutphen used?

26

























26*
