Island Time

Here is a pic of how the system works...

Electric.

Nope. There will be a heat exchanger between fridge and freezer. Not yet installed. I'll post a pic when it is, but there are 2 50mm dia tubes between fridge and freezer. There will be a SS plate/cover over them on freezer side, and on fridge side a temp controlled fan takes air from top of fridge, blows it across the plate in freezer, returns it to fridge. There is no air exchanged between fridge and freezer, as that causes frosting. Basically the fridge runs as a parasitical load from freezer. So both cabinets from the one condenser...

Its an Ozefridge. Its air cooled until the condenser reaches 38 deg, then it swaps to water (fresh water, borrowed then returned to the tank). Uses eutectic tanks for holdover. Once finished, I hope to be back to one run per day, about 30% of the time in the tropics, less here in NZ... Does not really use the water cooling in NZ, except sometimes in mid summer.

Current state... coming along slowly...

Oh, and what Brand or production boat? I can show you installs on Hanse, Jenneau, Bene and a few others...

The answer is "it depends". Best way would be to take a look, as makes and models of all devices are needed to answer that question. No decent marine electrician will install a system that does not comply with the current NZ regs -AS/NZS 3004 (and therefore meets Ewof stds). The main issue here is both Audio and Visual alarms before a batt disconnect. Entry level (one install I'm doing on 14th for example) will be approx $4k installed (using existing DC-DC), 314 A/hr fully compliant. Another I did recently was $14k, 942 A/hr, Dual alternator conversion etc....

Same. Also, why do they wait until a vessel has sunk? Takes lots more time and $$ then!

What would you like to know? I work out of GH, and have a few customers here with Lithium conversions. 2 more upcoming... feel free to call me if you wish. Matt Neptune's Gear Ltd 0221539176

The v60B (simrad version is RS40b) is a good unit, but does not have wifi. It's $1758 Incl GST. Its not supported by a Navman 550, which is why I suggested the NAIS500 and an MFD (Plotter, with wireless). NAIS with Splitter, GPS ant, and 7 inch Vulcan is about $2800. Its a bit less than the V60B and a MFD... Happy to Discuss with anyone interested. Matt 0221539176

Dont rely on Marine traffic at sea. It can be a long time behind (an hour or more) real time. A ship goes a long way in an hour!

OK. AIS transponders with screens or wifi are a bit pricey, especially if you want wifi as well. The digital yacht ait5000 doesn't have a screen, but is a transponder with wifi - its $2300 incl gst. Considering you could buy a B&G MFD AND a NAIS500 for about $2500, that might be a better option... that would give wifi via the mfd.. As BP says you don't NEED anything (even a yacht - people have crossed oceans in rowboats!)

shorthanded in a small boat a transponder is better than a radar reflector.... what are your instruments? (Other than the Navman?)

Its 5mm Acrylic. Bit more progress today with a test fit before side on fridge and top on both

The lifejack tether thing is interesting. I used to be involved in whitewater kayaking, and have training and experience in swiftwater rescues. There are special life jackets available for this. They include a harness and tether. The tether connects to the jacket above the waist at the BACK. This is because a front mounted tether will submerge you in fast water. A rear mounted tether brings you to the surface. The tether have a quick release at the front on a simple lever buckle. This system works very well, and many swiftwater rescue guys wear an inverted knife mounted on left shoulder...htt
