Adding 2nd battery?

[hostage]

I bought a 2011 Regal 2300 and it has 1 battery stock. I would like to add a 2nd one for redudancy. I know how to wire the battery selector up, but my main concern is how should I fasten the 2nd battery. I have plenty of accessible room in the bildge. I don't like to drill anything into the hull. Can I just strap the 2nd battery to the 1st one?

Yes, but I wouldn't do it. Bats are heavy and the first Bat is screwed to the deck, screw the other one the same way, just don't use long screws. Remove on of the screws holding the first Bat and see how long they are and do the same

You don’t want a 50+ pound battery flying around yhe boat if things get rough. Strapping one battery to another sounds like a particularly bad idea. Just make sure any screws you put into the boat are sealed well and you should be OK.

I don't know about your setup, but my batteries sit on a "deck" in my engine bay with the actual hull far below. The "deck" is horizontal plywood and the V shaped hull is well below it.

The suggestion by @alldodge Is a good one. Pull an existing screw to see it's length and copy that. Just make sure you are not screwing into the actual hull.
