  1. Hi Kenny, Gulf Harbour Yacht Club. Give me a call, we can likely find you a spot. Matt, 0221539176
  2. If you have a float on trailer, bearing buddies are a good idea, or you'll be changing bearings pretty often. Unless it's really only used for launching, not road transport. Brakes can be an issue as well..
  3. Most of those trailers don't have Keel Rollers. They are float on trailers completely without rollers...
  4. It's a float on trailer. Steep ramps are good. Thee last little bit can be winched, loads are big if your dragging it! Some vesconite slides on the base would help a lot.
  5. Fair point. When I posted this I was thinking about an example of Alternator load dump management, not an instruction diagram of how to install a complete system. It is NOT saying any particular LiFePo4 units can do a bank of 4, does not say how to config BMS's, or fuses. But it DOES show a basic way of using your alternator (externally regulated with correct voltages, and hopefully temp sensing) with LiFePo4 batts. Which many web sites say you cant.
  6. This is a good example of a basic system
  7. I suggest anyone who has an inflatable jacket manually blows it up and jump in with it on. Try it. Make certain it works for you. Then try again with foul weather gear on, and whatever you normally carry. This will give you confidence if it works fine, and let you know if you need to upgrade. My offshore jacket has crotch strap, hood, knife, plb, and a small but decent led torch attached. It is deliberately a manual unit, as I have had to use it several times as a harness, getting overboard to cut crap off the prop etc. seems that’s always the middle of the night….
  8. It is a requirement of 150n inflatables to keep the wearers head above water. Not to do so means the jacket does not meet the NZ standards. Type 401 is the standard.
  9. Nonsense. Type 401 - inflatable Achieves buoyancy by either a: water-activated switch manual pull cord May include a mouthpiece Designed to keep the wearer vertical during unconsciousness Comfortable and convenient to wear at all times Must provide 150 newtons of buoyancy Guidelines for inflatable lifejackets Download nationally agreed guidelines to help choose the right inflatable lifejacket, and know how and when to service it.
  10. Untrue. Automatic ones certainly do this, and are required to to meet the safety standards. In fact the manual ones do too, but obviously need manual triggering.
  11. This is a basic electrical question. The breaker is there to protect the CABLE not the load (winch). Cable sizing is done by a Load (amps), Volts, and distance (including return - it's a circuit, remember!). Normal allowable volt drop over the cable is 3% for essential circuits, 5% is ok for a winch. There are several good cable size calculators available online - like this https://www.fabhabs.com/dc-cable-sizing-calculator If the system works now, and the spec of the winch motor is not available, does the cable get warm when the winch is operated under load? If not, the cable is ade
  12. IMO this was bound to happen eventually. Interesting inside info here https://www.stuff.co.nz/sport/opinion/128263816/history-shows-that-taking-the-americas-cup-to-spain-is-the-right-call

  14. Send the pics to the harbormasters...
