  1. Firstly we’re in the tropics are you ? Some chart data is very unreliable and other isn’t, plus is it fog or just dark night ? And have I been there before ?

    Stand off until daylight.

    Or use satellite imagery data, radar, chartplotter, navionics on another device, in other words all available means including someone on the bow as you can always see or hear something no matter how dark the night is.

  2. Yes Navionics, if you look at the two images Vanuatu Vatu is only visible in one also

    all systems have there risks, it has a declutter mode effectively that drops stuff as you zoom out, I always create a route not to follow directly but to use as a reference line so I can zoom in and out and still know we are heading in the correct general direction 

    I guess this is so it can be run on mobile devices I’m assuming 

    I like it as I run an iPad in the cockpit and encourage all crew to use it while in watch, when I first sailed offshore navigation was a dark art that was guarded by one or two aboard and was done in secrecy way down below at a hidden table, not quite but I like all crew to be situationally aware at all times, even my 3 year old grandson can use an iPad. He FaceTimes us every few days when he gets up

    The key to all systems is knowing there limitations

  3. Plotting a course from Minerva to Savusavu 

    Put in a few waypoints to go up between the islands in the Lau

    However you then need to zoom in and follow the route as many things don’t show at low zoom

    I guess no more than driving to work along SH1 and getting cleaned up by another vehicle, does that mean you shouldn't go to work?? Does that make it a safe practice?? Life is full of risks, some we take knowingly based on the odds of not having it go wrong. The other is being in a situation where the unexpected happens (as happened to Encounter) with fatal consequences, would Goodhew have been there if he thought they were in danger, His business, his reputation, putting his charterers at risk, I doubt it. It was up to MNZ whether to put it before the court, to say they had no choice is a cop out. it is the public and Goodhew who will pay for the court case, not the individuals who made the decision to prosecute.

    The moment you go to sea you are entering a high risk area, and most of us manage to survive, every thing MNZ does in these cases is reactive, it doesn't bring the dead back to life. 

    Sort of

    But more like driving a school bus to the limits in bad conditions and 5 kids got killed when you lost control

  7. Not a hundred percent but believe that they are possibly shorting marks

    trackers can ping a time as they cross them and race management could call the race at any one of these points

    Just my guess but I’ve been involved with theses tracker a lot

  8. Not exactly rough, typical to good offshore conditions 

    alloy work hardens and will show very few external signs before breaking 

    As a safety inspector there’s not a lot we can do other than ask the owner to check with the manufacturer or get an engineer to sign off on it/get it x rayed , they can look fine but I’d never use that as a rudder stock. But all materials have their weaknesses, stainless at least tends to crack on the surface long before it weakens in the centre, carbon will make lots of noise usually long before it lets go

    Biggest job of an inspector is to ask if you’ve checked / considered all the weaknesses, at the end of the day it’s only a visual inspection and I won’t be sitting in the raft with you. Still it’s surprising how we always find a few issues, can’t think of any boat that’s got 100/100, 90 is pretty normal

    Most of the production boats don't have watertight bulkhead. Some have dams - didn't work great for the titanic! 

    Also,  an 85mm alloy rudder shaft wouldn't meet cat 1 here in NZ.

    Just register offshore and away you go

  10. Always go larger than you think you need 

    You will find other uses once you have it

    mounting in battery box is a good idea, however you need to fit a 10 amp breaker on the 230v side as close as possible to inverter

    If you want to drive north of the Brynderwyns then Rob Harrop at RH Engineering on Port Rd in Whangarei has made me all sorts of custom pieces out of custom materials and at a good price.

    I’ll second Rob, he recently made a small nylon/plastic roller for my bow thruster and had to machine a stainless two piece bolt to fit it.

    great workmanship and all done in no time at bugger all cost

  12. We have two chart plotters and iPad with navionics, nobody ever looks at the plotters

    did Fiji last year, never used chartplotters for anything other than AIS

    The CP are old E80 series, I need to add a wifi  hub I believe then I’d get all the plotter info on my iPad

    Did you hear the commentators call on that?

    "Meanwhile, Burling couldn't start a lawn mower..."

    To finish first ‘first you must finish’. Aussies started better
