The 55-year-old usually lives aboard her yacht the ‘Blazing Shadz’, moore

Mammoth undertaking!

Yes, I agree with that, however that's why I put in that link. Other (not LifePo4) lithium ion batts are generally not considered as safe as LiFePo4. Perhaps this link is better https://www.lithiumbatterytech.com/lifepo4-vs-li-ion-vs-li-po-battery-complete-guide/ and I've quoted some of it below... Composition of Cathode, Anode, and Electrolyte The cathode in a LiFePO4 battery is primarily made up of lithium iron phosphate (LiFePO4), which is known for its high thermal stability and safety compared to other materials like cobalt oxide used in traditional lithium-io

https://www.anker.com/blogs/others/lifepo4-vs-lithium-ion LiFePo4 is considerably safer than Lithium-ion... As tested by ABYC.. might see If I can find that report if I have time...

Id just like to re-iterate -the issue is that (IMO) Lithium Ion has no place on a yacht. LiFePo4 only!...

Personally I've NEVER seen a recreational vessel with a fire proof battery box... With LiFePo4, you are MUCH more likely to have an electrical fire at a high resistance connection or failed appliance than at the battery. Pretty hard to make the entire electrical system fireproof. IMO better to put the main battery switches somewhere easily accessible and/or have remote cut-off switches so you can easily shut down the power source. And decent extinguishers. I think a LiFePo4 battery fire is EXTEMELY unlikely, especially in a system that meets the standards for monitoring and auto shut

Yes And standards are NOT normally retrospective. The current NZ legal standard is the one I quoted above. If you are after a commercial vessel install, best to speak with your local MNZ electrical surveyor.

This is what the CURRENT standard Says; 2.9.3 Additional requirements for lithium ion batteries The following additional requirements apply: (a) Lithium ion batteries shall be installed in locations that ensure the battery manufacturer’s specified operating temperature limits cannot be exceeded and are appropriate for the IP rating of the battery and its management system. (b) Each lithium ion battery shall be provided with a battery management safety system (BMS) either integrated into a battery pack or as a separate component located adjacent to the battery. The BMS shall cont

No. The 800's and the 810's use the 51mm thru hull...

Great upgrade from Class B for an offshore vessel - means the satellites can see you ALL the time instead of MOST of the time on class B...

anywhere in NZ? Mana is pretty good - Wellington - $500/m for a 12m....

Make sure whatever you get is FCC compliant (or IEC). It's illegal in NZ to use an uncertified transmitter. For your info, a NAIS 500 (B&G or Simrad) is $955 + GST, and is compliant.

Also note that the standard is NOT retrospective, despite what some inspectors are trying to apply for EWOF's.... Its a shambles, and has been for years, with the electrical registration board exonerating themselves and trying to make the inspectors liable for any issues that come up in applying their standards. It's not surprising that the inspectors are cautious. Yes, for any new vessels its going to get difficult....

From the NZ standards site; AS/NZS 3004.2:2014 Current Date published: 27/06/14 So, no, there are no current standards requiring IEC compliance. The current standard says "Lead-acid storage batteries, alkaline and lithium ion storage batteries shall not be placed in a common cabinet or container or in close vicinity to each other." "2.9.3 Additional requirements for lithium ion batteries The following additional requirements apply: (a) Lithium ion batteries shall be installed in locations that ensure the battery manufacturer’s specified operating temperature lim

Normally Yachts use the B&G version - V60B. I've put lots of these on customers boats and had no issues.... If the display is too small for AIS and you have a MFD or Triton2 displays, they can do the AIS instead... via NMEA2000...

What BooBoo said. The amount of rudder blade forward of the pivot point is what provides rudder balance (ease of turning). Those rudders look like they drop down to probably fwd of the pivot point - it's essential that they lock down properly and cannot move aft in their cases - even a few mm makes a big difference. So the balance on the rudders controls helm load, but as Booboo says, the centre of lateral resistance v the centre of effort of the rig denotes how MUCH rudder is needed to counter any rotational forces. If you need a few deg of rudder to keep the boat sailing straight, then

I'd be interested to read of any incident with LIFEPO4 batteries being identified as the cause of ANY fire, ashore or afloat, BMS failure or not. LifePo4 batts are VERY hard to make burn (ABYC tried to do it and couldn't) - other Lithium chemistries have no place on a boat IMO.

Or you could try Rats (member on here) - send him a PM...

Yep, I've got a good one, just needs lower seals done. Low hours, excellent condition, was used on a duck punt...make an offer.

Imo this is a leadership failure. All crew should be warned and aware of possibility of a gybe when sailing deep, esp by the lee. No-one should be positioned even close to where they could be hit, regardless of convenience. Crew safety is paramount, and any helmsman, tactician or skipper should be well aware of any time when this is possible.

Depends on the platform. LINZ NZ do raster and vector charts for NZ for free - but you need a system (like opencpn) that can display them. None of the main Marine Electronics companies support them...

Just a note BK, now that Garmin own Navionics, and Navico have bought C-map, all the development work from Navico is now Cmap... There are several levels of charts, the basic one being "Discover", then the advanced one being "Reveal" NZ Reveal charts are $294 + GST, Discover is $146 + GST. There is not yet a Reveal for the pacific, Discover (Pacific Territories) is $294 + GST. From Navico - reveal "Cruising, fishing or sailing, C-MAP® REVEAL™ charts offer the very best of C-MAP. With Shaded Relief, including game-changing Reveal Seafloor Imagery, Aerial Photography, Satellite Overlay an

The 800 is obsolete, replaced by the 810.

There are not a heap of Laser 2's around. Should not be too hard to build a new rudder and stock if you have the old ones for measurements??

Id go now or Tomorrow... Always watch developments, and stop if needed...
