Too small to be adding 2 deep cycle batteries
and decks and extra stuff.
It'll probably be overloaded with any more
than 2 smallish adults just using paddles.
Unless I'm misinterpreting what this is,
it's a 12 foot long 36 inch wide jon boat that's
probably riveted.
Do yourself a favor and get a bigger better
boat to do all those mods to.
Or at least buy all new high quality PFD's
