1.2 metres x 2.4 metres (4’-0’’ x 8’-0’’)
A simple raft can be made from two 1.2 metres x 2.4 metres (4’0”
x 8’0”) sheets of 10 mm (3/8”) plywood or particle
board with a 100 mm or 150 mm (4” or 6”) thick PlastiSpan
board sandwiched between.
Bolt the raft components together with 150 mm or 200 mm (6”
or 8”) galvanized bolts. If one of the bolts is increased in
length, an extra nut and an eye provides attachment for an anchor.
A raft using 100 mm (4”) thick PlastiSpan insulation board
will support up to 225 kg (500 Ibs). Use 150 mm (6”) thick
PlastiSpan insulation board for support up to 340 kg (750 Ibs).
