So I'm at the lake and the beach wheels are at home in a slight state of disrepair, not an issue as there are several people that can give me a lift to the waters edge
no problems...... until I decide to go sailing by myself, ok so I have to fix up the beach wheels....


then the grey matter started ticking over......


Why is it when we are at the beach we watch powerboats being unloaded, back it down the ramp.... boat floats off and is held and vehicle and trailer drive out.

simple


the trailer 'sinks' during the loading / unloading process and the boat floats on or off as required



I've seen it hundreds of times as most of you probably have as well, where cat sailors seem to have a fight in extracting the beach trolley from out under the boat when launching or indeed when trying to get the wheels back under the boat so it can be brought back up on the beach.....




so can someone explain to me why our beach trolleys float



just asking
