Sort:  

I'm building a 'battery trough" on top of the keel and under the floor. The boat had twin Volvo Pentas so I expect it can handle the weight.

be sure to vent the batteries to let the gases escape and not blow you up...

that would be a bad day.
I was considering sealed batteries for that very reason.
or perhaps (gasp) lithium ion.

the only batteries i know of that dont gas (even sealed ones) are the AGM batteries and they run around $350 for a 100ah battery. my new ones here are sealed and have a gassing warning. lithium batteries have to be charged just right or BOOOM...

well fooey.
back to the drawing board.
I suppose I'll have to put the batteries where the engines were...(I can do that)...it has a vent (and had blowers) to the outside)

I guess I'll use the keel trough for non flammable storage...or maybe just leave it open as a companionway.

you can hide your sex slaves down there...

it's only 2 ft deep by 2ft wide by 15 ft long... midgets perhaps?
or inflatable?

"honest dear" speaking to the wife "that's not a sex doll..that's a life preserver"

sounds good to me... you could always lay them down and get two in there head to toe... with room to spare.
