booring????? Noooo come back...my friend has a Centurion 18 lightweight with a 460 Tunnel ram Berkeley-jet jetboat and I did cut today up all the rotten wood in my 21 Sleekcraft Exec .jr which had a 454+ a Jacuzzi 12 YJ. I´m thinking of putting a smallblock Twin Turbo in it....
One has to have a little boat too to play with...

Greetings from Finland...we don´t have snow here yet And I´m as high as Anchorage...

Mikeyfin:

The primary differences were as follows. For the hull, the bottoms were flat to a shallow V with cavitation plates across the transom, not trim tabs. Lengths tended to be in the 17 to 24 foot range. Prop shafts tended to have a main strut forward of the rudder, with whip struts just aft of the thru hull for those that had very low angle shafts. Engines were at the transom with a drive shaft going forward to a V-drive. Engines tended to be blown or turboed big blocks, except for the APBA class boats like SK and SS.

Ok so regular Drag/Skiboats mainly that you run with..I was thinking more on the Big offshore boats, you mentioned Bob Nordskog being the first with a true offshore boat in the early 80´s how about the others and was there any differences with the Big Vee´s to the east coast ?

Mikeyfin:

In this era, nearly all of the big offshore boats were designed and built in the south east and east. We in the west either bought used or new boats from them. Thunder Alley was the origin of many of our boats: Cigarettes, Apaches, Aranows, Scarabs, etc. These boats would generally run in the 90's--much slower than the current designs.

The smaller west coast boats that initially went offshore with Nordskog as I described were generally faster. But with their shallow V, lower freeboard, exposed engines and dry stacks, they were not nearly as sea worthy. But they were sure fun.
