Maybe you could make a floating dock, I think those blue barrels can be found at a coke or pepsi distributor, then just pull the boat up a bunk board and/or carpet.

Also get a righting line, leave it tied on when you flip ( you will flip, it's like a HDD hard drive, it's not if but when)then you throw the line over the hull, you don't want to be in that water very long.

Have fun.
