The deeper water ramp idea was bouncing around in my head for awile
I am glad I went that route, they worked great ! I am sure I will go that way on the 28 also

I will test it Saturday, if water pressure is an issue, I do have a file, some west systems epoxy, and paint.

I cut mine with 40 grit paper with sticky back on a 1" pvc pipe. Cut like butter.

Any idea how "thick" the hull is at the ramp area? Ron, your ramps are pretty deep!

Tom, What were the results of the deeper ramps, i.e., how much higher were you able to go with the cases and with what pressures?

Rainy, windy, cold, ran it anyway. Water pressure is now 23 psi up from the 12-14 I had. That is at 1 7/8" up. The ramps work very well. I will try it a little higher as I run 15" diameter Dewald.

I looked at mine thru the drain plug holes (fittings and bezels are out) I would guesstimate bottom thickness to be 3/4" @ the very back tapering down to 1/2" @ the front of the ramp.

My math says with the 1/4" to 0" ramp > 1/2" +/- left @ the rear and 1/2" +/- @ the front of the ramp. (appears to be solid glass, no core material in that area)

Thanks, Exactly what information I was needing!

You could just drill some test holes

What size do you think are appropriate?
