Boat Sandpit with Sail

Mark and cut 45° angles at both ends of both 2x12 hull sides, using a speed square as your angle guide.

Position the two hull sides on a flat, level surface. Apply exterior glue and screw the deck boards to the edges of the hull sides with 2-1/2" deck screws.

Flip the assembly over. Apply glue to the mating surfaces and screw the 45"-long 2x4 and 2x6 hull end pieces to the angled ends of the hull sides.

Screw the two mast pieces to the inside of the hull sides, centered, with glue and at least four screws per side. Drill a hole in the top of the assembled mast for the sail boom dowel and thread the dowel through.

Cut the fabric to 45" wide by 3 yards long. Fold and hem the sides and ends, then fold the corners in and stitch to create a channel for rope at each corner. Screw the I-bolts into the corners of the deck boards, then tie rope between the I-bolts and the sail, pulling the sail over the boom dowel and tightening it down.
