    Bruce speaks "batteries" better than me:

    Firefly Oasis batteries on OPE website

    "It's all how you look at it." From the link:

    Firefly G31: $0.17/kWh

    Lifeline GPL 31T: $0.55/kWh

    Also, I didn't pay retail.

    That helps!
    If they last 3x as long as regular lead-acid batteries, then they're a bargain.

    Gale warnings were posted yesterday so RYC cancelled its small boat midwinters. An intrepid Laser sailor went out anyway, but before long he was escorted back into the harbor by a watchful rib driver. Over in the normally placid waters of the Oakland Estuary, OYC's midwinter race was abandoned. It was gusting hard most of the day, causing Surprise! to bounce around in her slip out near the end of E dock. Sometimes she does that because she wants to go sailing, but not yesterday!

    After checking Flicker's docklines over in Brickyard Cove, Ed Ruszel stopped by for a chat. Then as the day blustered on, I was able to finish a couple of projects.

    If we took a wave wrong and Surprise!'s cockpit was filled with water, only two thin speaker cones would have kept green water out of the boat. I've never been a fan of cockpit speakers anyway so out they came. They were replaced with 6" inspection plates. Cockpit tunes are not forever banished - it's possible to install speakers in the inspection ports, to be replaced with the plates when desired.

    The bigger project, mentioned earlier in this thread, is a second NMEA 2000 backbone for the backup autopilot. This was installed in the lazarette to keep the cables shorter and connections easier. The backup AP computer, control head and heading sensor are Simrad components that came with the boat. The rudder sensor is shared with the primary B&G H5000, and the drive is one of Brian's Pelagic cockpit drives I saved from Ragtime! It all works but I only got through a dockside calibration before I ran out of day. I also need to decide where to mount the control head, since it would be hard to drive the boat from the lazarette!

    The coiled wire is excess compass wire. I read somewhere that you should not shorten it. Does anyone know if that's true and if so, why?

    The boxes in the upper left corner are the double-pole switch for the shore power, and a galvanic isolator. It bugs me that they aren't straight so I'll probably fix that the next time I'm camped out in Surprise!'s voluminous lazarette.

    Tunes in the cockpit, great! Speakers in the walls of the footwell in the cockpit? Um...UUuuuuuuuuummmmm.

    NO.

    Bob, What are the strings for that are tied to the seat locker latches?

    Sorry, can't help with the AP compass wire question without just speculating.

    The latches are a bit loose and don't have holes in them for locks or clips. The strings cause them to bind enough that they won't flip open easily.

    The string on the right also ties the bilge pump handle (kept in that propane locker) to the boat, as required in the SER.

    A bluetooth speaker might be a good bet so long as the speaker is well away from compass, etc.
