Battery Stowage Improvement 2

To make enough room to fit the new boxes I removed the original battery trays and mounted them direct to the supports attached to the boat's framing. The boxes are firmly clamped by broad stainless steel straps bolted through the bulkhead. The lids are a snug fit and have pegs arranged to keep them wedged in place.
These have done a season now and gone is the 'thud' of the batteries sliding around when the boat tacks!

Starboard battery - boat's 'house' services

Battery stowage improvement 1

Enfys has two batteries both of about 100Ah stowed low-down just abaft the cabin bulkhead in the engine space, one port and one starboard.  They are connected via a BEP cluster switch and arranged so the port one is for engine starting and the starboard for 'house' service. As built she has a tray in which each battery sits held in place by a loose stainless steel strap and a basic plywood drip shield to protect them. Like this did not feel that they were well enough secured or protected - the Finesse does not have a self-draining cockpit.

I made two boxes out of 9mm marine plywood sheathed in glass mat and resin to make them stiff and watertight. With lids and cut-aways for the leads, the batteries are held down by webbing straps and the whole box can be lifted in and out with battery in situ.
