Cradle Design for Boat Lift

[Francisco San Miguel]

I am considering installing fore and aft hull bottom support runners on my lift cradle. My boat is presently in the water and I would prefer not to take it out for the purpose of directly measuring the deadrise of the hull at various stations along the hull. Could any one with a similar boat lift tell me approximately at what angle to the base (looking at cross sections of the hull for the after portion of the hull where the deadrise is about the same) line should I cant the runner pieces so as to maximize their contact with hull bottom? Any ideas would be greatly appreciated?

I was wondering????

I was wondering if you could get these measurements off a 26M trailer? Best I can do. Good Luck.

Small boat cradle

I built a cradle for a small boat while it was still in the water several years ago. I used 2 2x6's running parralell and covered them with that blue tarp junk. I placed it between 4 trees so I could lift the boat using the trees to hold my block and takle up. Put the cradle under the boat and inflated the area encased in blue tarp, with great stuff. let it set over night and set the boat's weiht on it the next day. Worked great. Custom fitted cradle.

thanks

Yes, thanks very much for your suggestion. It is precisely what I did after thinking about it for a while. I obtained the deadrise of the stern section from the aftermost trailer support using a stifff cardboard template. I gave the template to the installation contractors who used it to cant the upper edge of the fore and aft runners ( 2"x6"x14 ft. long) placed 30 inches apart (to coincide witht the fore and aft longitudinal sides of the double bottom ballast compartment). It worked fine.
