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 the rig & or sails need adjustment to suit.
Personally I'd not change ANY naval architecture until all other sources were exhausted...

I wonder if the launch had Lithium ? Looks as if started in the engine area and this follows other incidents where the BMS failed in NZ and offshore.
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...

Anyone familiar with both C Map & Navionics for Pacific charts? Fiji predominantly, but they're usually bundled.
Time for an update for the chart on the B&G gear, interested in which y'all like better?
We have C Map on the B&G gear, and Navionics on iPads & phones.
It's interesting (TERRIFYING) how much they can vary, and while one may be better for a few Islands, then it's miles out & the other is better.
Thanks, pic for reference! Lagoon at Ongea
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

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...

H there , just about to do that trip from opua to nelson soon, you mean 2 days from opua to New plymouth? but this is like almost 400 miles ?
thank you.
It's 420 odd nautical miles from North Cape to Nelson. 3 days for most boats, or 2 to NP, and one to Nelson. 24hr days... Opua to Nelson Id go W coast.

Haven’t tried it yet myself and the next one is a paid gig so won’t risk it.
From what I’m told it’s the airnz that stops you in Auckland as they are liable to fly you home if your rejected at the other end
Only had them try that with me once. Asked for a supervisor, who read the appointment letter, no problems...
A stamp is possibly not necessary, but anything that makes the letter look more official might help.
You could, of course, check with your airline. Just record who you speak to, and time/date, or even record the call...

I've always managed with an appointment letter from the vessel, Stamped with the vessels stamp and signed by the owner/skipper, saying you are appointed as crew on SV XYZ, registration details, from date XXXXXX as skipper/mate/deckhand whatever.
Vessel is currently in Fiji waters and expects to depart approximately XXXXXX.
Never been an issue...
Commercial Mariners do this all the time.

Well, this is interesting "the builder Perini, has stated Bayesian had positive stability to 73 degrees with the board up and 88 degrees with the board down."
So she would have capsized in a mast on the water incident with everything battened down! That, IMO is not a seaworthy keel yacht...

in GH marina at present...

Saving on marina fees as I understand it...liveaboard.

Many of the boats had flogging sails and other signs of lack of preparation. It WAS forecast..... Lee shore as well for many

Through an inverter off a lithium bank on a Garcia 52. Running Starlink by far the biggest draw on a daily basis other than the watermaker. Interesting philosophical comments not wanting to be connected. The boat wouldn't exist without the ability to pay for it; and with a budgeted opex of minimum 130k kiwi per annum - I think being connected to the things that fund annual activities necessary. The plan for the next few years at least is for the boat to be used 3-6 mnths each year at present there remains a need for the boat owner to be able to engage and direct his business interests in real time with each of his CEOs and wider senior staff.
BK's one is now 12v. Installed in a flat mount (so no motors). Draw varies depending on what's happening, but 4-5a. Still a lot over 24hrs, but way better than the inverter option with the std starlink router...

Huh? I'm a bit slow tonight - I don't follow, so I have to ask - why is that?

A lot of his issue was, as is common, other boats. There is no safety in numbers! Tough to find when the "hurricane holes" are crowded... IMO don't stay in the hurricane/Cyclone zones in season, move on with a month or so to spare - the seasons are expanding...

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...
