Boat batteries - in cabin or not

[trueblue]

can 2 big batteries be installed in the main cabin space - in a cuddy cabin boat?

any risks from gas coming off the batteries

just looking at options for getting weight off the transom, and forward as possible

They should always be in a well ventilated place. In the cabin wouldn't be good....IMHO.

My yacht has the batteries in the cabin, and so does nearly every yacht I know of. Never been a problem for me

You mean something along these lines ?

If so happy to run you thru whether its suitable for your rig and if so what might be needed.

Might give u a few ideas

I had been thinking about making a tray and installing both batteries on it and sliding them under the anchor well - could then secure down the tray easily.

cabin doesn't get closed up at all. would just have to cut back my bunk cushions - but if they could be up the front that would get nearly 40 kg's off the transom and get it right up at the bow which would help on both fronts

I wouldnt be thinking bow mounts but then i dont even know the boat u have. Some details and maybe strip the cabin and pop up a piccy of it might help too. You're looking for about 120-230mm clearance as central as u can go and personally...not too far fwd. batts dont like pounding and you'll be trying to reduce vibration and added forces as much as u can. They're best down back in theory but as batt tech gets better more are whacking them fwd. You see big bow mounted dual agms in bass boats buit bear in mind they dont see much rough water action. To me the best weight placement is keel line about 1/3rd back from the bow coz it only seems to improve most boats...but usually not practical. Does she ride better with someone in the cabin? How old are your existing batts and ever thought about agm's ?...far superior and longer lasting for the added punishment.
If you have the bunk space but not the height its easy enough to raise the cushion height which also provides ventilation. Extra strong mounts are essential for the g forces and i also went with vibration matting under them. The port batt in the pic is only a temp car batt for the setting up but a 100ahr agm is much bigger and can weigh 30kegs..u dont want that coming loose.
Anyway..get back with a few details...plenty of smart guys in here can help out but some details of the rig would help cheers.
