This concaved one worked really well for us 11" at the transom. There was a step built in after the transition. This was designed by Doug Wright and Todd D. on a napkin at dinner- built out of awlfair (no wood to rot)....

Don't know your dead rise but have wood shop cut two strips of wood to match your dead rise giving you a flat level surface to attach a 3/4 to 1 inch strip on top to be your pad where you will have high compression giving you lots of lift cutting friction 7 to 10 inches.

Joe's concave, never saw that before

Joe is a Bondo man...

Very forgiving and stayed on the pad at all times above 30 mph. It was built to be my son's first trainer boat.

...cuda...you were evidently never a slalom water skier in your youth...haha... o'brien, maharaja, saucier, etc. slalom water ski's all had the same concave designs with the big aluminum skegs with holes drilled through them. this is where pipkorn derived the idea from. they tracked excellent. all us water bugs in junior high & high school would use a dato blade on the shop class's table saw making our own custom laminated wood slalom ski's for summer time. time machine required...

Awesome replies. I have plenty of Awflair available, but think the main structure will be coosa, epoxied to the bottom. I really like the concave pad, as that is what I I’m thinking will work the best.

...this is a photo of a 39' velocity hull plug that was tooled, but a mold was never pulled from it, nor a hull produced, but is a nice example of another nice pad bottom design...

I beg to differ I had some gorgeous Connelly inlay mahogany skis

concave has been around for ever, I just never saw Joe's Bondo special

When I was 15 my brothers 1964 Triumph was passed on to me most of the rocker panels were rusted away so I balled up newspaper to fill the hole then covered with a few gallons of Bondo, the beginning of things

to come.

I like to make them squeal

To go thru all that and not build a mold?

That 39 looks like the 22

just longer
