Hi Tony - yes I agree most heartedly with your approach to the boat rack concept on camper trailers. With 4 X 800NM. gas strtuts on my model, and a 'split system' that hinges approx. half way up the 4 corner posts, it virtually has to travel through 180 degrees both unloading and loading a boat. The big problem as I see it, is getting those pressures right for the system to operate efficiently in 'both directions'. If you are satisfied with a loader that 'drops' the boat on its side then has to be man handled fully and returned the same way, thats fine but at 65 I try to make things a bit easier. With the system I have, the struts help initial opening, then assist by not letting the rack, whilst loaded, drop onto the ground too hard. BUT when you take the boat off, wow, hang on to the rack because it wants to go the other way real quick as the strut is more compressed in the lowered position than in the closed position on top of the trailer. I have thought of the hydraulic ram system, such as a portapower where you can 'pump it open' and control the load onto the ground, then pump it up off the ground and control its loading back onto the trailer, simply by slow release of the valve fitted on a hydraulic hand pump. This aspect would only work where the rack hinges through 180 degrees. I will be interested in your comments. Regards DWM
