H23: bought 2 jack stands
Hi,We have an H23 (same as Steve), and we bought 2 jack stands a few years ago to help with the bottom painting. With the boat on the trailer, the _forward_ jack stand goes inside the trailer rail, with 2 of the 3 legs touching the rail, and jacks up the boat there. The aft jack stand goes just outside the trailer rail, and we tie it on securely to the rail in 2 places. Then jack it up until it is about 1/2" off the bunk board, and unbolt the board and remove it. This is pretty easy. We also use large squares of 5/8" plywood under the jack stands so they don't sink into the lawn. This ends up feeling pretty secure: I have never felt any qualms about the stands punching through the hull, or shifting and letting the boat drop on me. I think it was well worth the price of the stands, and we've used them every year. Paint under the boards on one side, and then swap sides. 2 Jack stands is plenty. I think they were $130 or so (per each? per pair? don't recall...)
