Sub Benchy Keel

Sub Benchy with Keel to make float right side up in tub

All real work here was done by papi8570, so thanks papi for my kids bathtub submarine! I just wanted to make it float, not on its side, so I made a
Keel for the sub. Its not perfect, but it does the trick. I filled it with play sand from the sandbox and then epoxied the keel to the bottom of the
submarine. I didn't know the boyancy, so it was a guess. If you want it to sit a bit lower, you could add some water in after the sand.
