If your putting in some items like USB ports, etc keep in mind that some sport an LED or like a radio, use a tiny bit of power to maintain the radio settings. (Mine does)Pretty much planning on having, or already have most of the things you mentioned. Do you have suggestions on brands for the auto life jackets?
with my rewiring of the boat I’m using a switch panel that not only has a 12v power port, but also USB.
I’ve read that spray foam is not closed cell? I’m planning on using expanded polystyrene board under my planned aluminum floor and in unused gaps under seats (if there isn’t already foam there and shoved into spots under my planned storage area/deck. I forget what the formulas were, but if I remember right I’m estimating that I’m getting rid of 30lbs and adding 5-600lbs worth of floatation. I’ve seen a few guys who have been swamped by waves or some jerk in a wakeboarding boat, and the foam saved not only their hide, but the boat and all the gear too. They just putted to the shore, bailed out the boat, and got back after it.
Those tiny power drains will result in a low/dead battery after a couple weeks of storage.
Invest in a good dedicated to the boat battery charger/maintainer that will float a bit of a charge to overcome the electronics drain and keep the battery at 100% charge when your ready to go.
