Re: Trailer for a tri hull
I used to have a 78 Glastron trihull. It had a Holsclaw roller trailer with a center pivot. When the water was deep we'd just launch it without bending the trailer at the middle. If the water was shallow we'd unlatch the pivot on retreive and the rear of the trailer would rock downward with the weight of the bow. As the boat came onto the trailer the back of the trailer would tilt down, and once the boat's center of gravity was above the axle the rear section of the trailer would come back even with the tongue section. Then we'd relock the center pivot. My dad bought that boat & trailer for short money, I didn't even notice the pivot when I was a teenager. I "found" it many years after I first used the trailer when retrieving in a low water situation. It was a little over engineered, but it saved me a few times.
