That's be pretty hard to answer. I do know a few, just a few sailors who have switched from C34s to C36s, or v/v, so I doubt if there'd be many who'd know the dimensions of BOTH.

What you should do is figure the size of the batteries you want to install, and measure YOUR battery compartment.

I assume you're planning a 6V golf cart installation. If so, the choice of the batteries you're planning to install may not be the same as many who have gone before you.

Measure once, cut twice...:)

I mounted our start battery under the galley sink in back of the large drawer. It is a group 27 and is for start only if it is ever needed.

Triatica,
While the C34 and C36 share many systems and components, their layouts are completely different. What might work perfectly in a C34 might not fit in a C36, and vice-versa. I'm not an expert on the C34, but my guess is that the battery compartments of the two boats are different, as the layouts are so different. In the C36, some owners have glassed in a platform just aft of the aqualift muffler for a starting battery. Some owners have used the space just above and outboard of where the current batteries are. Some owners have used the area under the forward game table seat. One owner I know of simply put a battery in a box under the nav seat. Lots of choices. You will probably also have to add a second battery switch, and/or re-wire the existing batteries. You might want to do a search in the old forums, and check on the Tech Notes CD.

PS-It would help if you would update your signature for this forum. Hull number would help people give accurate answers, and a name would be nice, too! :)

[QUOTE=Triatica;892]Any guidance around where you would mount the start battery? Seen a few ideas thrown around, but figure you would know what's the best trade off for effort/cost/practicality/cable run.[/QUOTE]

As Tom has noted, the physical relationships are so very different. But some things don't change between boats, and one of them to me has been the "desire" to "make the reserve bank" be as close to the starter as possible. I have been saying "nonsense" to this concept for years. Why, because of a few things> 1) wire is sometimes less expensive than making a solid "home" for a new battery; 2) access to the reserve bank is important for maintenance and where people put them, on your boats and ours, sometimes makes no sense because once in, they can't be seen!; 3) wire runs to existing switches become convoluted.

I've seen, personally, two fine C36 installations. Jeff Berman's [I]Perseverance[/I], a Mk II, has six 6 V golf carts under the aft settee seat forward of the galley with a reserve bank starboard. John Reinman's has his house bank to starboard with a reserve bank fwd of the galley. Your boat, your choice.

And, I suggest we stop doing the "start" bank thing and begin calling it what it should be: a RESERVE bank, and only needed when necessary - the house bank is just fine for starting our engines. I've had some long discussions about this on our website and on co.com, and they include "Maine Sail" who many of you know quite well.

Keep it simple, wire it well, make it accessible and design and use the "strength of wiring diagrams." :):):)
