These two separate collecting busses are only SWITCHED together 1) >by the generator transfer switch or 2) by interlocking manual switching or >an internal relay design in some inverter/chargers. Exactly what he said. It's critical to understand that the bonding of neutral to ground must take place ONLY at the source (inverter/genset/isolation trans former). There is a very good reason for this. Should you have multiple point s of bonding, if one of the bonds failed then there is a possibility that som e segment of wiring would have an unbonded neutral but you might not notice. This could lead to leathal voltage being present in a conductor (the neutral) usually at zero potential. THIS CAN KILL YOU. In addition to Nigel Calder's book, I also highly recommend Charlie Wing's "B oatowners Illustrated Handbook of Wiring".

You do not need a vented loop, because the pump already has a check valve. Now, my editorial comment: I would not do this if I were you. This is a bunch of extra plumbing, a new 3-way valve, and one more thing to forget. Easier to just empty the tanks every morning when you get underway.

I'd recommend that you keep the existing alternator for the start bank and get a new high-powered alternator plus a smart regulator for the house bank.

LA Licata writes: >Might be useful for those that just need their bacon fix.... Growing up in the Arctic, the only bacon we had was canned. It was my standard breakfast food for 5 years working on our boat. Nothing like a nice batch of french toast fried in bacon fat cooked up on a Coleman stove in the 8 foot square cabin of a landing craft out on Hudson's Bay. I found that half a can was just perfect for breakfast. Oh to be 15 again :-) It's great stuff, the only downside is that it's a bit saltier than regular bacon. However if this really bugs you you can soak it in water overnight and it will draw out the salt. One other nice thing is that you always have a can to pour the bacon fat into. By the way, the other thing we used a lot of was canned butter. Again, excellent stuff. Only downside is that it sort of ages like wine. It's slow and subtle, but after several years it's very very "buttery". When you have fresh butter after getting used to aged canned butter, the fresh stuff tastes pretty bland. Finally, I am assuming that pretty well everyone is familiar with Eagle Brand condensed milk as a coffee creamer. It's fabulous, and best of all it's so think that when the can falls on the floor in heavy weather you have several seconds to pick it up before the milk runs out.

The Nicro-type mushroom solar ventilators come to mind but >I'm looking for just the solar element since the fan is located in a distant >locker. My suggestion is to dspense with the solar panel and just use a very low-powered 12 volt fan. The small ones draw under 50 mA, so even a small batter will power one for months without draining the battery (50 mA is 1.2 amp/hours per day, that's only 36 ah/month). For what it's worth that's what I've done, and those fans move about 10X the air that the Nicro fans do.

One word of caution: Current transformers can generate LETHAL voltages on their output if there is no load (meter) attached. Ensure that the wire through the middle (the red #6 wire) is NOT energized before you poke around.

The KY jelley is glycerine based and hardens up when it dries, adding a bit of sealing. I learned both of these tricks from a professional marine pipefitter, and they really work.

I have a 45 year old Detroit Diesel, so trust me when I tell you I go through these things in bulk (I lose about half a quart of oil a day, I know that sounds like a lot but then again the engine holds 8 gallons of oil). In any event, go to a commercial boat yard or lubricant supply house and buy a bale of the good 3M oil absorbant pads. I get the ones that are about 20 inches square. Here's a link: http://www.jamestowndistributors.com/userportal/show_product.do?pid=7717&familyName=3M+Oil+Sorbents I get my at my local commercial shipyard for about $50 per bale of 100.

I've run a jailbroken phone for 24 months (we develop iPhone software and that was the only way to do it in the early days). If you're smart enough to hack an iPhone, you're smart enough to either (a) not do stupid stuff or (b) keep a special hacked phone around for fun and games. The equivalent T&T statement would be "Running 2 micron filters is not a good idea. They can clog when you drop plastic spouts into your tank.
