Re: Troubleshoothing help: Can't run appliances

As far as the electric heaters are concerned there is one thing nobody has mentioned.

You have a battery bank of 690 AH - 230 x 3. That is measured on a 20 hour rate, meaning you have 690 AH only...

Re: DC Battery Rig

Makes no difference if the alternator output (B+) goes direct to house bank positive. Never should be wired through the switch.

Re: DC Battery Rig

B+ should go to the house bank. That is the bank most in need and it makes no sense to run that current past the start battery first. Field sense to house as well.

Re: Inverter connection to battery - Fused?

Several thousand short circuit amps actually.

Always fuse the inverter positive cable near the battery post, or directly on the post. For a 2000 watt inverter using 2/0 cable a 250 amp fuse is...

Re: True blue water boat extinction a fait accompli?

True, but still a bwb I think. Sort of a modern version of the Nicholson 35.

Re: 3 Battery banks and 1 MPPT charge controller?

I would run all charge sources to the house bank. Either an ACR or Echo Charge between house and start battery. An ACR to windlass battery. If you ever have to re-set the anchor 2 or 3 times to get...

Re: True blue water boat extinction a fait accompli?

Rustler in the UK is building traditional yachts, as is Cape George in the US among others. They don't exactly "dominate the market" though.

If anyone wants one full keel yachts are available new...

Re: True blue water boat extinction a fait accompli?

The Sundeer/Deerfoot designs were not, according to their designer, optimized for upwind sailing. They were narrow with waterlines virtually as long as the boat to be easily driven by a fairly low...

Re: True blue water boat extinction a fait accompli?

Dashew's designs were narrow to be easily driven and were meant to be couple boats. They have short rigs as the hull doesn't need a lot to drive it, at a cost of less than ideal light air...

Re: Rewiring with Upgrades

250 or larger fuse. For starting circuits you are allowed 150% of wire capacity.

Re: True blue water boat extinction a fait accompli?

Boreal extreme? No, a Pogo is extreme - good offshore boat for some though.

Boreal is a conservative boat that can go anywhere.

Re: A twist on "The best blue water boat" question.

Then stainless would be a good choice. Bronze and steel in close proximity in an electrolyte (salt water) is a lousy mix. I do not know of any steel or aluminum builders who install bronze seacocks....

Re: A twist on "The best blue water boat" question.

I don't think that is a good idea for a steel boat.

Re: The extreme end of electrolysis

The problem in a marina if your boat doesn't have a galvanic isolator, or ideally a isolation transformer is the AC ground (green wire) connects you to everybody else's bad wiring scenario. It is DC,...

Re: Reverse Polarity

I don't think reverse polarity will harm any appliance. I do think it can be an issue for an inverter with an AC input pass through as the inverter (when inverting) connects neutral and earth,...

Re: Reverse Polarity

I don't know about that. I assume you are referring to the reversal of the hot and neutral wiring. Inverters internally connect earth (green) and neutral while inverting. If hot and neutral are...

Re: Reverse Polarity

I read this as the AC earth (green wire) and DC negative are connected together. In North America this is proper. Nowhere do I read that the AC neutral is connected to DC negative on the boat.

Re: Redoing electrical connections

If the terminals are improperly done, I agree. Properly done the only potential for corrosion is the tinned eye screwed to the terminal black. Either a double crimp connector with added heat shrink...

Re: Reverse Polarity

Actually it certainly can be dangerous.

Most boats have single pole AC breakers for each circuit after the double pole main breaker, only breaking the hot (black) wire. In a reverse polarity...

Re: Tanzer 27

Looks like the tackle raises and lowers the centerboard, assuming there is one. The pole keeps the opening for the line entry above the waterline. Probably the mount for the cabin table as well.

Re: Propane system Question???

He said "at the tank". I assume that is in a locker or certainly not in the boat's interior.
