>>1258392i think that's memory, not twist
>>1258404ehhhhhh
>>1258401probably but i think it might float
>>1258375i think you could get some more stability out of it if you add some aluminum plates to the corners under the water, which could be done pretty cheaply with 8 really long bolts (long enough to reach through the foam, the 2x4, some washers, and a few nuts) then some washers and nuts and 4 aluminum plates. it would add $50 to the price at most and make it a lot more stable because when one part tries to dip it has all that extra resistance, and the other side has all that extra resistance when it tries to pull up.
its kinda daft probably but might be worth trying
