    Lithium v AGM

    That's so cool, I recently did a delivery on a yacht with lithium iron batteries and what astounded me was the rapidity of the recharge the yacht had electric auto helm and electric fridge and I definitely felt the lithium iron was a disruptive technology same as H. F. Radios are being displaced by Sat phones.
  2. Thanks re subject being talked about before. Yes an Inreach does not comply as the rule is written. The rule can be rewritten the rules are arbitrary. The rules are up for review see YNZ posts. An Inreach costs about a third of an iridium go and the the running costs are quite a bit cheaper - thats the point.
  3. With regard to Rule 18 Communication I was wondering does anyone have an opinion on Using a Garmin Inreach Satellite communication device ( txt only. Not voice) I think it could satisfy the requirements of rule 18 off shore communication - a lot less expensive than sat phone or HF radio no voice but is that an issue? Comes with other features like weather and vessel tracking if you want it.
  4. I had lazy jacks for several years on my Townson 38 and honestly it was one of the best days work ever getting rid of them, not worth the hassle better off without them.
  5. For me the best system has two seperate alternators, an engine alternator and a higher capacity house alternator. I like the redundancy. In an emergency the engine and house system can be put in parallel. I realise not all installations have room for two alternators but for my money if you can then two seperate electrical systems : an engine system and a house system are the way to go.
  6. Not ideal but you could knurl the shaft then machine knurling to fit coupling. Another way would be to sleeve the coupling . I have seen this arrangement with grub screws before but it's better to thru bolt the shaft and coupling because in astern the only thing preventing the shaft from pulling out are the two grub screws Shaft exiting is a major event.
  7. I have a Yanmar j series and there is a small gauge wire from the start switch to a relay. The start switch energises the relay which activates the starter solenoid etc. The relay is situated on the engine. It works well and is a way of getting around a voltage drop on longer runs of light gauge wiring.
  8. I put a mechanical fuel gauge on my tank same issue re fastening to a tank wall about 1.5mm. I used self tappers pan head with a fibre washer under each head and plenty of sealant under the housing. It's been over 15years and no issues. The key is a washer or o-ring under the screw head.
  9. It looks similar to my TP 30. If so it is tuneable that is you can tune it for sea state and gain by pressing buttons. The user manual is available online if you search TP 30 user manual. Also check the T.P cannot move interdependently of the yacht what I mean is if the TP moves the internal compass thinks the boat has changed course when just the TP has moved.
  10. The beauty of two alternators is the redundancy offered, this is a good enough reason on it own. I've had a 120 amp alternator charging house batteries plus original Yanmar alt charging dedicated engine battery for almost 20 years and have never had a problem starting the engine. It's a simple system and 100 % redundancy you won't regret it.
  11. From the album: Yanmar exhaust elbow

    Off a 3Jh2 Turbocharge Yanmar (new) Anyone want it?

    Keel bolts

    It's best if they are all tight carrying equal strain, you won't break a 19mm bolt, Put your shoulder into it on the end of a 3/4 inch drive ratchet or similar. Monel is the best totally unaffordable these days.

    Keel bolts

    Sometimes Monel has a greenish spots from the copper, another interesting thing it's slightly magnetic if you file it the dust is magnetic. 316 should not be magnetic.
  16. Got to say I like your'e posts Wheels, very informative.
  17. Hi I re-caulked my decks early this year, a couple of things I learnt 1. I bought Sika 290 dc out of UK for less than $30.00 a cartridge delivered. 2. The UK Sika was a different consistency than the locally bought stuff and easier to use. 3. Bond breaker tape makes it a lot easier to remove the old caulking, just cut down either side with a stanely knife and pull it out. Also I used a small tenon saw with a couple of buttons fastened to the blade to lower the groove depth then a small chisel, then cleaned either side of the groove with sandpaper glued to a 5mm thick piece of wood. Did it
  18. I worked on a ship that had Intersleek, great while the vessel is hardly in port but when it stopped for a couple of months the bottom got fouled quickly. I asked the paint rep about putting it on my yacht, no he said only good if your underway most of the time.
  19. Hi my genoa is 31 m and I have Harken 48.2 thats two sizes up from what the harken book says and I can get away with a smaller winch handle most days but definitely wouldn't go smaller. But really I think Harken winches have been disappointing.
  20. Happy to report I have obtained a Tiller Pilot case (thought there might be a dead one somewhere!) thanks all !
  21. Hi can anyone help have a navico type tiller pilot with failed electronics. I need a new case only. Willing to pay for it. Thanks could email me on vesper1@xtra.co.nz Dave C.
