why the set back on these boats

Does it do something special, mine has none with a 275-300hp RUDE on it. It went like crazy the way it is or would it go faster with a setback and how much of one would you need........... It is a 21 ft. hst

There is a very good article on the Scream and Fly home page on this subject.

The HST hull is a 20 foot hull so if you are measuring 21 feet you may already have 12 inches of setback with out knowing (mine has around 18 and it looks almost as though it is part of the boat.)

I have heard differing views on what an HST needs but since mine has the setback I doubt I will remove it. You say yours "went like crazy" but that is a pretty subjective measurement. Have you had a GPS reading and if so what was it? With as much horsepower as you say you have you should see speeds with an HST around 100mph.

A real good source for HST info is Balzy who posts on this board frequently. He has had his HST above 100mph. Good luck with the boat and if you live in the upper Midwest (or even if you don't) you should attend Firewater as there will be at least three HSTs there (I hope).

They normally need a bunch of setback unless you have a light layup. Are you running with neutral trim when it's flying? If you are still positive trim then you would benifit from more setback. Go to http://www.Hydrostream.org and search around. I wrote an article about the HST a couple hundred years ago.

I live out here in the desert where there is only bass boats and pontoon boats (oh yeah, many many jet skis). I don't won't to sound dumb, but is that a HST in the photo Balzy?

Yep..........

I live on the Canadian prairies and I've never seen a Hydrostream boat of any type. There is an owner's group web site that is really good with some great information about all of the models. Check out:
