From www.heatexchangersonline.com: "Our line of double wall brazed plate heat exchangers are suitable for potable water, food industry, pharmaceutical and various other applications where the possibility of cross contamination must be eliminated. Each double wall plate actually consists of two thin plates welded together with a small air gap, which is vented to the atmosphere. Should any leakage occur as a result of cracks or pin holes it will be detected on the outside of the heat exchanger. " I'm actually shocked that Raritan does not use them, as it seems to me it's a liability waiting to happen. I'm guessing that AYBC rules also require a dual wall design. In fact, even the heat exchanger for my heating system (Hurricane) is double wall. Scott Welch "Things turn out best for people who make the best of the way things turn out." - John Wooden

Over the course of a summer of cruising, we watched all of "Six Feet Under", and the kids like Seinfeld and The Simpsons. TV shows are MUCH less expensive than movies to buy (typically about $25 for 12 episodes) and one of the things I really like is that you know exactly how long they are going to be: 22 minutes for a half-hour show and 52 minutes for an hour-long show. No commercials, you can hit the pause button any time you like, and if you really want you can watch 2 or 3 in a row.

jweakley@visi.net writes: >Are these hose fittings Coast Guard approved? Short answer: Maybe. Long answer: The approval is based on a hose "system" (hose + connectors). If you take a close look at the spec sheets of CG approved hose, you will usually find some small print stating that the hose is only CG approved when used with the approved connectors, and giving you a list of which connectors are approved.

And this prompts me to mention one of the most useful tools I have on the boat: large jaw vice grips. http://www.amazon.com/Vise-Grip-12LC-12-Inch-Locking-Pliers/dp/B00004SBB1 These are great for removing filters. They are also perfect for the large nuts that go on through-hulls, getting sanitation off old toilets, loosening stuck shafts, and they will also grip a through-hull from the outside. I promise, the best $20 you will ever spend. Scott Welch "Things turn out best for people who make the best of the way things turn out." - John Wooden

Before you do this, you might want to check out Discover Batteries, in particular the 2 volt L-16 versions. See http://www.discover-energy.com/files/datasheets/EV216A.pdf The problem with the Odyssey is that the largest battery is only 214 Ah. In order to get more Ah you will need to parallel multiple 12 volt batteries, and that is problematic. The EV126 batteries offer 1170 Ah and you'll need just 6 in series (for 12 volts) or 12 in series (for 24 volts). These are also available in 6 volt versions (390 Ah) versions. I used these because the 2 volts were not available when I installed them. Scott Welch "Things turn out best for people who make the best of the way things turn out." - John Wooden

I have mecanical counters on my bilge pump, and I've just had another one fail (they don't seem to withstand salt air). After a bit of searching I found a new product that looks great. Price seems pretty reasonable too: http://www.celectron.co.uk/overview.html I've ordered one and will install it this summer. I'll let everyone know how it works out.

However, I would highly recommend the multi-function digital AC meter: http://bluesea.com/category/6/23/products/8247 This will show volts, amps, watts and frequency (the later is useful for the genset). Plus it has alarms for over-current. I have several and am very happy with them. One other nice thing about Blue Seas meters is that the mounting system is very easy to use, you just cut a round hole and a large threaded ring on the back holds the meter in.

The manual for the unit states that it is a part number M28748-/8-D10LIA Evidently the M28748 series of connectors are fairly widely used in military equipment, but a search for that particular p/n didn't turn up anything, none of the parts houses that I deal with handle mil type connectors, and I really doubt of I would have any luck at all as an electronics
