Title: Cav plates on jets?
Post by: Motorhead68 on December 30, 2014, 07:23:29 PM
So here's a question I have: Why do some jet boat hulls use what appear (to me) to be cavitation plates? The Southwind tunnel dragster hulls come to mind immediately. Does it have to do with the shape of the hull on that model? Is it a drag race or circle track thing?

A guy down the street from my folks' house in Vegas has a bare hull in his yard, and it has plates like that, but it doesn't have the extended section off the back of the transom for the jet like the Southwinds do, so I'm pretty sure that it isn't a Southwind. What are some other brands besides Southwind have used that setup?

I'm not in Vegas. I just said I know where this a jet hull in Vegas that has what appear be to be cavitation plates on the back of it like a V-drive, and I was just looking for an explanation as to why boats like the Southwind Tunnel Dragster and this mystery hull have them.

He's asking, because he lives in Vegas...

Placecrafts, Mach 1, wildercraft a to name a few. Most of the " single pickleforks" have the air plates. 👍👍👍👍

Yes. I have.

Doesn't mean one could not benefit from the adjust-ability of some box blocking....
