Hey There,
In order to comply with Rule 6.1.27 "One securely fixed 12-volt battery weighing not more than 25 kg.", and in light of the knockdowns last year in Rochester, I was wondering how people are securing their batteries and where they are placing them.
Thanks,
Pierson |

I have my battery on the starboard side of the mast step. I glassed 2 small blocks to the hull on either side of the battery with stainless padeyes screwed to them. Small piece of prestretch secures the battery. Did the same for the anchor and ouboard in the 2 lockers in the main cabin. Did Rochester and East coasts and a couple solid wipeouts nothing moved!!

| My battery is under the sink on the starboard side. We thru bolted two stainless steel closed fairleads on either side of the battery and used some line to tie everything down. At the North Americans in Rochester this past September we also took our share of knockdowns. The battery tiedowns worked fine. total cost about ten dollars. total weight less than 8 ounces. total time to install, about 30 minutes. Don't forget to seal the thru holes to keep the wood dry. |

Lambert,
Did you attach those fairleads to the bulkhead? Where does your water tank fit into the equation? I like the idea of rigging the battery some place other than right next to the mast with water dripping down onto it--under the sink seems like the best place other than in the lockers under the bunks.

I agree the water could be an issue. I have my battery in a case and has never been an issue. I like the low central location for the 50 lb battery I carry. My install definately takes a bit more time than Lamberts.

Plan A Interior Layout 2 shows the storage point for the battery to be port side in the locker built on modern boats or effectively as on our 20 year old Rogers, under the low shelf port side, on the cockpit floor. I do not believe it is legal to store a battery forward of this point under the mast mast step. even if you wanted to do so. Our battery on Hedgehog is stored in a moulded container and restrained by a webbing belt and buckle.
Regarding battery storage under the sink, there is no longer a need for a drain tube and a waste container, so that does create space, however, depending on the boat alll up weight you might need to store a water container of up to 10kg under the sink so there will not be space.

Hedgehog,
Which rule prohibits that battery from being carried forward of the port shelf ('nav' table in the older boats)?

There is no specific rule number that addresses this. There are two pictures that do not make it clear either. 'Plan A Interior Layout II' looks like the newer boats, that are made in Italy and the US, this is where the battery is in a storage area on the Port side behind the bulkhead. 'Plan A Interior Layout' looks like older model boat, and shows this same area as for the Head, but many people have their battery case mounted there. As well many boats have the battery mounted next to the mast.
I know that the new boats build out of Argentina, have the battery in a molded tray that resides under the port quarter berth.

| I keep the battery in a case and tie the case’s strap to a point at the forward corner inside the port under bunk area next to the anchor and chain. This minimizes its contribution to the boats moment of inertia. Straps holding the bunk boards down (the anchor, chain and motor also must be secured) are long enough to also secure the crews’ gear bags, keeping them also near the ideal location. |

Just to clarify the rules issue - as people below have pointed out, there are a variety of interior layouts that have been produced during the 30 year life of the J/24. The versions of Plan A are all legal - so that if you don not have a moulded battery case in your boat (as in Layout II) you are free to mount the battery beside the mast step as long as it it secure. To a measurer this means will stay in place in the event of a knockdown.
The 25 kg batteries seem a little big in that all they power is a few cabin lights - in some cases only one. A few power Sailcomps, but many have gone to solar powered electronic compasses.
However - see the post by Hans Spiller under rules on electric motors - we may need to rethink the whole battery issue as this evolves. |

Pierson,
my battery tiedown closed fairleads are mounted on the bulkhead between the forward face of the starboard side quarter berth and the bukhead just under the sink compartment door. I avoid drilling any holes anywhere near the forward bulkead in order to avoid any chance of water getting in. By the way, with the season just starting, I pull and recaulk all thru deck fittings. Much cheaper than repairing rotted balsa. |

| Putting your battery in a plastic case is a good idea. Remember that when salt water comes in contact with the sulfuric acid in the battery that hydrochloric acid is produced. Not a nice though, which supports the comments made about not locating the battery near the mast step. I would have thought that the manufacturer would have had a recommendation on the location but that is apparently not the case. Ken |
