  1. Good question: The battery ground terminal provides the ground. In a boat, we connect to a common ground because that is what all devices then use as the ground. The batteries supply that and all their ground terminals are joined, allowing every battery the same electrical level of ground. Think of it as the devices being sailors. Now they are all on one boat, working together.
  2. I’m an ABYC electrical tech. Your instinct is correct: Shorter runs are better. The size of the cables for DC electricity is determined by the load (how many amps are required by what device) and the combined length of both ground and hot cables: From battery to switch to circuit breaker to device to ground (bus bar) to battery. It’s called “common ground” because all DC grounds together. More than three wires should not be stacked on top of each other and wherever possible, only one per connection (terminal) because there is resistance with stacks of terminals and resistance causes heat and o
  3. As one who is hired to fix new boats, I would get a highly recommended rigger, boat electrician, engine mechanic and surveyor to each make a complete and thorough survey of a similar (same brand) boat at the dealer. Use that as a list of what’s wrong and subtract the needed remedies from your final negotiated price if the manufacturer won’t address the issues. Otherwise, accept them as things you’ll have to address. I would also pay attention to equipment installed that is crud: One popular boat manufacturer has electrical panels with about ten circuit breakers and electrical distribution that
  4. I use the Mary Conlin company in Los Angeles. They handled my quite complicated documentation issue, on buying my boat, beautifully and have been wonderfully supportive in helping me respond to tax questions, regarding this purchase, as well. They send me documentation quickly and are quite fair in their fees.
  5. PS - I would love to know more of Apollo V’s history and would welcome any tidbits anyone could share, so please feel free to write me a note. Thanks!
  6. Ahoy, mateys! As Sailingjunkiexl correctly identified, she was Apollo V, a foam-cored monocoque Kevlar 42.5’ IOR racer, built for Alan Bond. I bought her three years ago and am rebuilding her into a wicked fast cruiser. She was abandoned, derelict and close to being destroyed when I bought her: Paint peeling off in giant pieces, dead engine, horrifying corrosion issues throughout her rig, electrical system entirely corroded, dead and a product of BillyBob and many other issues. She’s repowered, has a nice new electrical system, water system, modern galley (I laughed seeing that old galle
