    Sailing to Fiji

    IF That was the cause, it is very poor passage planning - and that looks somewhat likely.

    Situational awareness! Never relay on one source of navigational data!

    Confirm your position with multiple sources, and ALWAYS do a high zoom fly through of your passage plan. Contrary to BP's position, waypoints are a highly useful navigational aid - one inserted into this route, several miles off the reef, to either side, while planning the passage would have avoided the issue. So would boundaries with alarms (easy to put around any danger points), exactly as you would on a paper chart. Radar guard zones with alarms set at a few miles would likely have seen the breakers.  Poor SOP's look to have caused the loss of this vessel.... A warning to us all. Take care out there!

    Who watched the doco-drama on the 1998 Sydney-Hobart last night?

    My starlink rate hasn't changed. $199/month for local roam.  Currently got several customers using it in the islands on the same (NZ local roam) plan. They use priority data when doing passages. 

    The issue with heaving to in the gulf is it's shallow, and never gets a fully developed sea state... Still, practicing is a lot better than not!. Island Time will heave to ok without help until about 40-50 knots - then if a wave knocks the bow down she'll try to sail away, and the helm balance is difficult to get right. Once on  the 'Chute, that doesn't happen. 

    I'd certainly use a series drogue if I had the sea room, and where I wanted to go was downwind... but I never have to date.

    wow. OK. I just saw the size of the waves ('98 Hobart) and assumed if one of those breaking waves came at you hove to, you'd be well stuffed.

    I did hear from some guys in that race they carried on as they thought turning around would be more dangerous.

    But you'd be mistaken. For multiple reasons. By stopping the boat,  you remove its kinetic energy, and a wave must then overcome its inertia before a roll or knockdown happens. This is why heavier boats can be better in extreme conditions. You also minimize the area of the boat that a wave hits, and present the strongest parts to the waves. Finally, it's quite remarkable the effect to weather that heaving to has, and, if using a parachute, the waves break over that as well, and don't really break again before they get to the boat, so that assists the slick effect that heaving to has.

    These days though, with much better forecasting and comms, you can avoid these conditions much more easily...

    Yeah, I'd be happy never to see that again.

    It was on a parachute, to help us stay hove to. 37 hours. Ended up with seas bigger than the rig - and even though the boat was at about 30 deg to the waves (deliberately, so you don't jump off the backs) the waves were as big as the rig, and in the lee of them, she'd stand upright, just to be over 45 deg and more on the crests due to windage (no sail, bare poles) with a couple of knockdowns included for good measure - caused by wind, not waves. That got pretty tedious pretty fast!

    I don't believe any sail boat would have survived trying to sail down those waves - but maybe a big modern racer, with helm changes every 20 mins, and sailing faster than the wave train - that's not us.

    The noise has to be experienced to believe. Wind speed was up around 60-65, but yes, we had gusts and some time displaying 80's, peaking at 93.

    Over 20 years ago now... seems like forever.

    Heaving to? In those waves? Really? Doesn't sound like something I would want to attempt….
     

    Absolutely. If you can stop, and point the bow somewhat into the waves, the strongest part of the vessel  is presented, as your slower/stopped, the time between waves is more and the motion is better. Sailors have been doing this for 100's of years (or more), but the art seems to have been substantially forgotten in the last 50 years. Most Ive ever seen is 93 knots over the deck, and I'm still here!

    Talking with my neighbour in the marina on Saturday and he casually mentioned he was delayed leaving for Fiji as his lithium batteries had swolllen up and he was waiting to get them looked at. He said he thought that there was no charge controller on them.   Sounds like a disaster waiting to happen so I asked him to disconnect his cables and perhaps move his boat away from mine. Perhaps I should also move mine away from his?

    Yep! Sounds like over charging. I've seen a couple of installs without any control in yachts that have come from offshore.:shock:. It's crazy. I re-iterate, there is, in  IMO, no such thing as a drop in lithium! And batts without BMS at all should not be used anywhere.

    4 stroke, right? They have very small jets, it's VERY likely a carb blockage. Take the jets out and clean them - they are very small in these motors, and will block with older fuel that has gelled a little.... Empty the fuel into your car, clean the fuel system, and fresh fuel, it will go fine....

    So that is a $29 fuse that is small enough to sit on the battery terminal lug, doesn't get in the way and protects your boat from electrical clusterfucks?

    Think I will get one. I was expecting something like an anchor winch isolator that needed to be mounted separately and would then need specific leads to and from it etc.

    Thats on the start battery. On the house, as I have LifePo4, I have a class T fuse;

    Ok, just catching up with this thread again. As part of the "management" of this marina, I can think of only two vessels in 10 years that have been asked to leave. I've been on the GHMVRA committee for 9 years.

    The rules are pretty simple. This is a residential marina, and the berths are people's back yards. Be respectful of this, and don't cause unnecessary noise and disturbance to neighbors. Don't discharge any pollutants  into the water. No more than 2 consecutive nights staying on board  - if renting - there are NO toilet or shower facilities. No commercial vessels (to prevent fishing charters leaving at 5am with 25 people etc). Boats using power connections must have an EWOF, and all boats must be insured, reasonably maintained etc.

    You are responsible for people visiting or crewing on your boat.  Work on the boats, like most marinas, cannot be contaminating the water, or other people's boats. Noisy work, like power tools, hammering etc must be restricted to short duration and reasonable hours - again, it's peoples residence, not a work site.

    We have a facilities manager, Steve Law, ph 021457268 who will know what berths are available and controls the rentals. 

    This is a well maintained, calm and quiet place to moor your boat.

    If anyone wishes to talk to me about it, 0221539176

    @Island TimeIT - what are the body corp fees for the apartment like where you are?

    They all vary - not all houses have berths. Effectively there are 2 sets of fees - village assn (ALL properties are members) and the subsidiary BC's of which there are multiple. Our one is a group of 12 townhouses. Our total fees (incl the 15m berth) are about 10K - but that includes all exterior maintenance, rubbish collection, insurance etc etc. IMO its a great deal...

    For some reason I don't follow, the value of the berths is not really added to the house values in the village, and we have even had lawyers tell prospective buyers not to buy here as the berths have annual fees! With that, though, I'd also say, you DONT own the berth, you just get a license to occupy while you own the property...

    But you have basically the same rights as if you did own it - you can rent it out etc, to all intents and purposes its yours...

    The Marina is a Society and supposed to operate solely for it's members boating needs, it isn't allowed to make a profit. At .present prices have risen lately due to the refurbishment of the piers. A typical lift and waterblast is around $100-130 with annual rental around $1400-$2000 PA depending on length

    that is very cheap. however prices rising due to maint is an issue we all face - the GHMV marina have a sinking fund for this - we just did a half life survey and replaced another 50 piles - steel this time. The fees I quoted above reflect the actual costs of running this marina. Without a hardstand or toilet/shower facilities...

    I have 10Hz H2183 (2013) SS and from what I gather from net the precision 9 is not significantly better. Looks like a NAC 2 would be the way to go.

    Ok, that's a much better heading sensor than the usual ones on an AC12!

    So Yes, a NAC2 or three would be an improvement.

    However, I have had customers complain about them as well, and also H5000 pilots. All the pilots need to be setup correctly, usually by more than just autotune. With the AC12 and the NAC series, the low and high speed settings can be used to have normal and running settings, rather than low and high speed. S turns are often the result of too much rudder gain, but can be wrong counter rudder settings as well. There is a pretty good description of this and how to set it up on pages 25 and 26 in the NAC2-3 commissioning manual. There is quite a bit to get right, incl

    Turn Rate, Rudder gain, Counter rudder, Auto trim, Init rudder,  Rudder limit,  Off heading limit, Track response, Track approach angle, Course change confirm angle etc, and then all again for the low/high speed settings. 

    I suggest you spend some time experimenting before outlaying some $$. Unless you want good wind angle steering - the AC12 doesn't really do that well...
