Thanks for the diagram, ogdrum. It helps. Why I wanted a AC circuit diagram is that I am going to install a 5.5kw generator and I want to make sure how to wire the generator into the ac circuits. I have two AC circuits, boat and and air conditioner. The boat AC circuit has an inveter in it that is not indicatedon your schematic. I want to confirm that the inverter/dock ac switch totaly isolates the dock current from the inverter with no possibility human failure to turn something on or off that will allow the two circuits to ineract with one another.

Does anyone have a detail wiring schematic for the AC circuits on a Ben 40. Thanks

While on vacation last week we made a 7 hr sail from Solomons to Saint Michaels MD. Winds were 15 to 20kts with 3-5ft seas with a short fetch. We were sustaining 8.6 kts through the water close hauled. When we were able to fall off to more of a beam reach we were seeing speeds in the 9.7 range. There was just a bit of weather helm but nothing excessive. Just more proof that these boats are absolutley amazing under sail. I still have the smile on my face. I have a short video of it and will try to post it.

Just a heads up. Saturday night we were set to anchor out at one of our favorite spots. I hit the down button on the windlass and nothing happened, just some clicking from the solenoid. Dropped the anchor by hand and went about troubleshooting the problem, which had escalated to a point where we only had 9V output from the house battery bank and all the DC devices were non functional. Beneteau now places a small but mighty fuse on the positive terminal post of the main house battery. It's part of the yacht council's standards for boat wiring. I found that I had 12.9V on the battery post but only 9V on the output of the fuse. I removed the fuse and found oxidation between the bottom and the battery post. Cleaned all the surfaces and now had a full 12.9V, a working windlass and full house power, especially the toilets. If need be I was going to remove the fuse for the weekend since it's a duplicate system anyway. I'll pick a rainy weekend and remove all the DC battery cables, then clean and treat them with a dialectric grease to prevent future oxidation. It pays to have a multimeter on board :)

Franc- does mike know his stuff or what.
Mikey- hats off

Franc, glad to hear they're taking care of you. That's one of the nice things about Beneteaus, you can get spare parts any where. Enjoy your trip.

Thanks Mike. Vitrifrigo America (excellent service!) helped us troubleshoot the problem over the phone and we were able to solve the issue. We accidentally damaged our thermostat so we are having it replaced.

Varnish vs Teak Oil in Alaska (looking for advice)

Hey Gang,   I've been spending quite a bit of time taking the old varnish off of my boom and interior cabin. Being based in Alaska, we have big temp swings (-10 to 75 F), and I'm debating just teaking all the wood and holding back on varnishing it. The thought would be that I would just have to apply more teak oil to it every time I went out, but I wouldn't have to deal with the varnish peeling so bad again like it's doing now. Maybe this is just part of the regular upkeep on any boat…See More
