Thank you for the nice comments,Happy new year to everyone
coming to this party a lil late, but a couple of things I did.
I used BB’s ( used with toy air guns ) they’re small with good weight. They fit anywhere and can balance your boat easily. Once balanced, pour in 2 part epoxy, enough to submerge them to hold them in place. Make sure to place them in the lowest part of the hull.
I used 3/4 oz fibreglass to wrap the hull with 2 part epoxy for water proofing.
Neptune, very nicely finished boat !
Best regards John,
