Best way to store a boat without a trailer

Hi all, i have to store a boat on the ground for a while, any tips on how best to do this. it is a 16 ft with a cuddy. weighs about 750lbs.
any suggestions would be greatly appreciated as i am clueless about this. cheers.

stacking old car tyres on either side of it should do the job

Yes Donal would be spot on. Even keel, sitting on tyres and tyres to the sides. You could prop the gunnels with timber to prevent the boat heeling too.

as the lads said above tyres,and double up at transom if your taking it off a trailer,small bales of staw if you can get them,when putting back on trailer,keep car jeep in nutrel and winch up,seems to work better than when hand brake is on,eddie............
