You guys are all nuts pushing a 20' boat that fast!

I remember my boat started to "Chin Walk". Thats when you launch off a good sized wave and your "Chin Walks" from Starboard side and slams on something on the Port side!

I began racing hydroplanes 40 years ago as a boy, since the days of the spade-hulled "B" outboard "knee-boats" with a Mark 7 Merc. I've driven a wide variety of boats at great speeds, and crewed offshore racing powerboats of 22' and 30' as a throttleman and driver, and I've driven on the water at speeds greater than 100 mph. That's my credentials.

Fr. Frank curious on when you joined the priesthood?
Was it during or after or both?

Stirrups and a kill lanyard.

ABSOLUTELY!

Long after. I became a priest in 2000. I stopped trying to exceed the speed of (fill in the blank) on the water back in '86. I learned that no matter how fast you go, you can still hear yourself grunt and scream as your body bounces and skips across the water at 80+ mph

Yes, it was MY body.

Why would anyone want to go that fast in a 20foot SeaCraft?I hit 50 one time in my skiff in a foot of water on a slick calm day and it scared the you know what out of me.I guess I'm getting old!

I don't really like going too fast, but I sure do like a 35mph cruise when I have to go long distances.

You can say what you want about controlling chinewalk at that speed, but that hull was not designed for that speed. Somebody is going to get hurt...

I really hesitate to post on this, butIMHO, either the guy going 55+ mph in an old 20' seacraft doesn't know that he is exceding the design and safety limits of that boat, or he has a death wish.

staying on topic.

what i am trying to figure out is how much bracket postition/flotation and motor weight/prop/trim/shaft length play into causing this chine walk on this hull. i really appreciate the on topic input so far, i just want to do all i can in setting up this hull to help relieve the chine walk.

Well i dont know if it matters but i have a 73 20 SF with the original 20" transum and a 225 EFI merc and im hitting 69MPH on a GPS. And without the wind, chop, and weight on boat, being perfect I'm chine walking pretty easy at 3/4 throttle.

[eggsuckindog]

Ok that is probably faster than anyone needs to go BUT, with his statement that the motor can't be trimmed much and he thinks the bracket may be too high - is it possible that the nose actually is not high enough and the boat is running too flat thereby causing the chime walk ??? Dr Frank
