This PrusaSlicer project cuts the original 3DBenchy.stl into parts, using 100% infill density for the aft hull and 10% lightning infill elsewhere. The resulting model floats upright when printed in PLA. This version is under 9 grams, but some of my previous test prints were over 12 grams and just barely floated, so there are many solutions to this problem.
I used PrusaSlicer 2.6 because its "center of gravity" visualization is somewhat useful.
The "Public Domain" license only applies to the slicer profile, as I didn't create the model.
It’s not rocket surgery. Boats need more weight at the bottom than the top. If you put it in water and it leans, shift some weight in the other direction.
PrusaSlicer has a ‘center of gravity’ indicator that removes at least some of the guesswork.
