Re: Running engine at anchor for hot water - load

And the math doesn't look good for solar panels and LFP batteries (actually LFP batteries make no power at all, so they aren't part of the solution).
Water has a specific heat of 1.16 * 10-3...

Re: Deck & cockpit drains - through hull reduction plan

Completely off topic, but I have to comment. The picture you posted up-thread shows 3 sails -- a reefed main, a full staysail, and a reefed jib. In my mind, reefed sails are almost always less...

Re: Bilge pump discharges

I used two of these on my last boat (two pumps, 1 very small, one as big as I could fit). Never had any issues.

Re: Bilge pump discharges

The cockpit has an open transom. Because it is not full width, there drains in the aft corers, but that simply addresses nuisance water -- any significant water goes out the transom.


I've often...

Re: Bilge pump discharges

I have long considered this, but much bigger. 12V bilge pumps are simply centrifugal pumps, and we have been building centrifugal pumps for generations. 12V pumps have significantly higher...

Bilge pump discharges

My boat has 4 "bilge pumps." Two manual pumps, an electric pump, and a shower sump pump (essentially a micro bilge pump). None are ABYC compliant -- but the boat has gone 24 years, 25,000 nm, 2...

Re: Deck & cockpit drains - through hull reduction plan

On my boat (also cored), every thru hull location had the core removed at the factory (so there is a 1' square depression in the inside skin). This ensures there is zero risk of water penetration...

Re: Best state to register a new-to-us boat

Which leads to the curious dilemma. My parents solved it by ignoring it for a couple decades. But, they lived in FL, where the boat was documented and registered and spent about 1/2 the year. But,...

Re: Does insurance really not pay up?

Fine print is OK, if it is clear. Sometimes it isn't clear, sometimes it's "the way it is." Unlike car and auto insurance, there is not normally much government oversight, and inexcusable fine...

Re: Does insurance really not pay up?

Interesting story, and yes you need to be attentive to your boat.


The story commented you can be "negligent" and still have an "accident" -- and indeed, I did. I failed to correctly line up my...

Re: batteries running to 0% at night

That's 50W, not 50W per hour. Or 50Wh per hour, which is a weird but useful consumption unit for variable loads (my fridge, for instance, runs about 60W when running, but since it has about a 30%...

Re: Remote Battery Terminals

In the vast majority of cases, you are correct, the terminal uses SS studs. That's because the current flows from direct contact between the cable terminal and the bus bar, with the SS stud simply...

Re: Boats that sat on hard

In general, the fact that it hasn't been used is a good thing. But, if it sits on the hard, it probably isn't being attended to. The chain plates can start to leak (or continue leaking), leading to...

Re: Remote Battery Terminals

Stainless bolts are indeed poor conductors. However, they DO conduct. With small (under 15A) battery chargers, the loss is likely minimal. Further, as the battery comes up to full charge, the...

Re: Wattage leak

I'm really not on board with "stray" current, the type that dissolves metal. 200W is 15A, and I can't imagine that 12V can push that much current through salt water (I can be convinced otherwise,...

Re: AIS transceiver antenna spreader or stern?

My AIS is older (~2012?), so probably not B+. I'm fairly certain I've seen my location on MarineTraffic listed as "yacht by satellite." It may or may not be "consistent" but it seems those birds...

Re: Dyneema broke at cover taper

Oh, I don't much handle line that small. On my jib halyards, yes, but they only go up once a year. On the main, the most of the handled part is covered (and at clutches, additional core inside...

Re: Bahama sailing newbie

I love to sail, and monohulls at that.


But OP isn't interested in sailing, and I infer that he is interested in staying places, at least for short stays. So, he needs to focus more on...

Re: Portable generator or not?

Oh, wow, yes. We have an off-brand hydronic diesel heater, and we truly love it. But, I've been hundreds of yards from it (walking the dog), and amazed at how loud it is. Even in anchorages with...

Re: Dyneema broke at cover taper

Agreed, you don't "need" Dyneema. But the benefit is huge! My 60' tail, of 6mm Dyneema, is much smaller than that same tail in 10mm (about 1/2 the volume). And the Dyneema is more limp so it lays...

Re: Dyneema broke at cover taper

You just stated you use 6mm for your halyard. It sort of reminds my foggy memory, but I'm pretty sure I knew that, and knew you were happy, and used that knowledge as validation when I settled on...

Re: Dyneema broke at cover taper

Dyneema (and Spectra --same stuff) is very commonly used without cover. One huge "benefit" of covered Dyneema is the ability to remove a large percentage of the cover where not winched -- by adding...

Re: Portable generator or not?

I think that a LOT of the concerns about noise are addressed by not running it at night. Run it from noon 'till 2PM, get your batteries topped up, and then not at night. Mid day, folks should be...

Re: Dyneema broke at cover taper

It is certainly not "wrong" to use 10mm dyneema on a 38 footer, but it is conservative. Samson recommends 6mm to 45', and 8mm to 50' (actually, "at least 50" because they don't provide...
