"Trying to figure out if I should bring beach dolly or make some kind of ramp and wench system ,what do you guys think? Could just back it to the water with some better tires"
Old thread but, I pull my trailer onto the beach at Pismo. I leave me ski on my beach dolly in the trailer and roll it out and into the water. If I wanted to fit two skis I'd need a wider trailer or I'd have to take the ski off the dolly to fit 2 skis side by side. Usually I have my bike and a quad in the trailer too. My dolly has a winch so I beach my ski after riding, then crank it up onto the dolly, much easier than loading the ski while in the water like most people do. Then I roll the dolly back up into the trailer. Easiest way for one person to launch at the beach that I can think of. If the sand is hard pack (low tide) I can get away with standard air pressure. If I go into the soft sand I air down the truck and trailer tires to about 20 psi.
