Dear all, my name is Simone,
a new member and can't post new topics because I have no creditcard (I live on Curacao, an island in the Caribbean).

I truly hope I can find someone who knows enough about Sutphen powerboats.

I'm thinking about buying a Sutphen Powerboad, build '92, 39 feet, two inside engines (800 hp each).
The reason why I want to buy this boat is because I want to offer powerboat chartertours to tourists visiting the island.

The sea of Curacao (offshore) is known to be extremely rough at times. Can anyone tell me if this boat I've got my eye on is the right boat for these conditions?

Many thanks in advance guys, any help I can get is more then welcome!
Kind regards,
Simone Leeflang

I'm close with a 1976 20' super pacer with berkley jet drive
Still working on ressurecting it as its been sitting for 15 years. Its got a 460 and pulled a max speed of 92mph with the jet drive in the late 80s.

Sounds like a nice boat, but I'm calling you out on the speed.
What was the hp on your 460?

Long story, the 92 max speed was with the same motor it has now but with minor changes. The 92mph blew after a month so it was rebuilt and detuned for reliablility, the current motor dynoed at 730hp but was only ran 2 hours(still only has 2 housr on it.) Before it was put away it ran close to 80 or so. Currently it has the 80mph motor with 2 hours on it. I've been working on getting it running again but with lack of a decent garage it looks like it wont be running right until spring.
It has a gale banks twin turbo bb460. I can get some pics here in a few as I've been wrenching for the past couple hours.
