This adorable boat sandpit features a fabric sail that acts as a sunshade.  It is just right in size for a couple of small children, and "seats" are built right into the hull.

I was inspired by this sailboat sandbox for these plans, but wanted to come up with an extremely easy to build version. 

Here's how we built it -

Below you'll find free step by step plans with diagrams and cut list.  

If you do build, please share a brag post or tag me on instagram #anawhite or @anawhitediy  - we love seeing how your projects turn out!

Step 1

Cut the ends of the 2x12 at 45 degree angles using the speed square to mark out the angle.  You can also use a sliding compound miter saw if you have one.

Step 2

Position hull sides on a flat level surface.  Apply exterior appropriate wood glue.  Screw the deck boards to the edges of the hull boards with 2-1/2" deck screws.

Step 3

Flip the project over.  Apply glue to areas to be joined.  Screw the 2x4 and 2x5s that are 45" long to the angled ends of the 2x12 boards with 2-1/2" screws.

Step 4

Screw the 2x4 masts to the inside of the 2x12s, centered on the 2x12s, with glue and at least four screws per side.  Use the 2-1/2" screws.

Step 5

Drill holes in top of mast for the dowel.  Thread dowels through the holes.  We left our dowel a little long.

Step 6

Cut the fabric into a piece 45” wide by 3 yards long.  Fold sides and ends over of outdoor fabric, and sew to hem edges of sail.  Fold corners in and stitch to allow a channel for rope to thread through.  Screw I-Bolts into corners of deck boards.  Tie rope between I-bolts and sail, pulling sail over dowel and tightening down.
