battery placement

Nice find, twisted. I cut an inspection hole in mine, but on the outside of the stringer, thats why I thought it was too shallow. Im thinking now, cut some holes like u did, epoxy up
The edges, use the cut outs as hatch lids and gain some storage. Can u post some pics with your camera in the hole facing forward & aft

Thanks
 
Ok here we go should be able to see much better now.

Ok so the whole thing is rectangular. The bottom slants away so the measurement to to the top of the slant. That is not how the battery will sit just dropped it in to show the fit.

I would not put the battery's up there, I would put in a hatch and use it for storage for something light, I don't like the weight and corners of the battery's resting on the hull , that's just my opinion
 
So how much room is there between the top of the battery and the underside of the deck? Obviously don't want to just drop the battery into a hole with an uneven bottom - will need to fabricate a base with a built in angle to compensate.

I'm thinking maybe a sandwich made up of 1/2" rubber mat on the botom, 3/4" plywood, expanding foam to make up the angle and a 3/4" plywood top for the battery to sit on. That means that a minimum of 2" of clearance in the shallowest corner. Is there enough?

Could probably get away with a 1/4" mat and 1/2" ply for a total of 1.25" if need be..

Follow up question - do you see any reason why I couldn't cut the access hole in the side of the step down rather than the top of the deck? Harder to get to but I have milk crates bolted to the deck in the cuddy and wouldn't want to move them, even occasionally for battery access.

Awesome !

Totally solves my trolling motor issue (unless I go 36v). Thanks !

Absolutely! In no time at all you can stick the trolling motor right through the large holes that will be in the hull...you could troll from inside the cuddy!
Brilliant...

Yea pretty sure a properly bedded and secured battery won't be much of a risk in my situation. But thanks for your kind guidance. I'll let you know next time I'm in RI -maybe we can hook up again..

It was a word of caution to the OP...as many have noted on this thread what he is proposing is somewhat risky.
That is a heavily concentrated load at the end end of the lever arm, without proper bracing this could be a disaster. In any case I wouldn want all that weight (somewhat) permanently mounted up in the bow area.
Sometimes we have to accept that the designers actually knew what they were doing.

The comment on your trolling motor was a joke...hope you enjoyed the bourbon.

Merry Christmas to All!

Maybe if the boat was used only in fresh water lake I might feel differently about the battery's upfront sitting on the hull because the pounding would be absent but in the ocean that's a differant story Good luck It does look good
 
Not speaking for twisted or jv, but I envisioned a cleat attached to the stringer on either side with a shelf spanning the void. Very similar to the shelf in the stern.

As far as the weight, I believe others who have mounted trolling motors on the bow have set the batteries in the step down
 
thanks for all the advice guys.

The plan was NEVER to have the batteries sitting on the hull it's self. At first i was going to build a large dispersion shelf that sat on the hull, but after reading what you all have said i'm going to change it up a bit.

in the photo i'm going to glass in a platform for the battery to sit on.
One side attached to the stringer, one side attached to the bulkhead, and the third side to the side of the set down. the photo is NOT correct because I don't have a photo with one of the bulkhead in it, but you guys get the idea.

This will make sure there is no weight on the hull skin.

Looks like a good plan. Will be very interested in seeing updates. Thanks for all the pics..
 
Let’s take a step back; what is the motivation for moving the batteries away from the stern anyway?

Maybe I’m missing something...but I just don’t see a good reason.

Unless you have hung an over weight engine on the stern why do you want to do this?

Thx, B
 
In about a year ish when I repower. I’m going to hang a 36 in set back bracket with a swimming platform and a 200 hp off the transom. I need to rewire the boat now to get a number of basic functions working. With the current under deck setup the only place for the batteries is the transom. With the planed extra weight in the stern I’m trying to offset it as much as possible. I’m doing it now one because I already have everything I need and two I don’t want to have to move the batteries latter rewiring the boat twice.
 
Hold on your saying you are going to put on a 36 inch extension( 3 feet sea drive swim platform) off the transom and put on a 200 hp hanging plus a swim platform so you can stand on ?
To me it sounds dangerous Like it's going to rip your transom off But that's just me I would really like to know what the big guns think, I love the steplift too but I don't know if I like that idea
 
thats awsome, i thought about that but lacked the nuts to start cutting holes.
with a 350mag/bravo 1 in my boat im always looking for ways to get weight forwards.

and yes i have trim tabs already
 
The most important issue seems to be how to secure the battery rather than moving the weight.

I'd suggest securing to withstand constant pounding in 3' seas.........meaning more securely set and braced than needed. " Overbuilt" as the saying goes..
