    DrWatson reacted to wheels in Clunks... What's going on here?   
    The thing is with Camshaft, Cranks, Chains, Cogs etc etc and any other solid mechanical timed mechanisms, if they fail in anyway, the issue is not intermittent. They all cause major and even catastrophic failures that would abruptly bring the engine to a halt. Or at best, the ignition of the Fuel would be compromised and result in a smoky cylinder or two or more. From my own experience, here are a list of things I found over the years. Maybe it might help someone one day.

    Broken lug on Camshaft = ruff running through out rev range. Smoking engine. Continual clacking noise that increases freq with revs.
    Broken Cam shaft = Engine failed to start.
    Blown Turbo= Engine was running at time, came to a halt with lots of black smoke. When turned over, sounds like it is trying to start, but doesn't and belching lots of smoke.
    Broken bolt on Big End Bearing = Engine running OK at idle with slight knock sound. Sound becomes very loud and ruff as Revs increased. Eventual complete failure with Piston Rod punching through the block.
    Injector pump timing issues = Engine fails to start.
    Cam shaft timing issue due to sprocket/gear losing a tooth. Engine runs ruff and fails to start again.
    Cambelt failure = Catastrophic failure of engine with lots of damage.
    Many various reasons for loss of oil pressure = all resulting in Engine losing revs and completely locking up in a very short time.
    Loss of coolant = For Cast iron blocks and heads, Engine losing revs and eventually locking up. After cooling down, engine starts and runs OK again and no apparently problems. May not always end up with such a good outcome.
    Small amount of Water in Cylinder = Engine came to stop and failed to start again.
    Large amount of water in Cylinder = Engine locked up hard on start. For smaller engines, no damage. For larger engine, one had bent Con Rod and one had cracked the Block although engine was running hard at time of taking a gulp.
    Broken spring/s in drive plate = Noisy/rattly sound at idle. One had no drive at all.

    That is all I can think of at the mo. I may think of others later.

    I had watched a few of their episodes on YouTube and am pretty happy they've decided to leave the country. They had no respect for lock-down rules or the social distancing measures taken under level 3 and were constantly whining about everything here unless they were getting a freebie in return for promoting it. Redneck, self entitled narcissists...

    Yeah we have a masthead tri. When motoring, the masthead anchor light serves as stern and steaming. Stern light on the pushpit it on its own circuit. 
    Ive never noticed much interference from the sidelights when I’m in the cockpit. The lowers are only used when motoring. So generally there’s no reflection from the sails. The lowers are mounted above the sheer, and the cabin cuts in as you go forward, so they clearly visible from dead ahead. I guess you wouldn’t see both from dead ahead if you were in a rubber dinghy and closer than 5-8m to the bow. 
    But thy work, they’re bright and the meet eu regulations.
    If i was doing lights myself I would make sure they met int colleges and YNZ be dammed.

    Rant. You cant' keep your cake and eat it too. 
    Some people screaming for the borders to open, other people screaming for them to shut and exclude even NZ citizens. Other people screaming that their rights are being removed and then crying for NZ citizens to essentially be incarcerated.
    Quarantine, and disease control is a very tricky business, and what we've learnt and are being shown is that in general half the population are below average intelligence. There will always be people in positions of authority that exceed their capability, be they politicians (on both sides), health authorities, security guards, police, and even hotel management. Last but not least returning NZers who're in quarantine also have responsibilities, and by their sheer numbers, some of those in quarantine will lack sufficient intelligence, integrity, or logic to fully meet their obligation.
    No, the system has not been perfect. 
    But I'm also sick of hearing about the "We'd have done it better" bullsht from the other side of the fence. Spouting empty rhetoric and a lack of details. Look at the rest of the world - it's basically screwed. Now tell me how exactly a different management of the situation would have let us leave level 4, 3 or 2 any earlier, or kept deaths to <30 at this point. There were ALWAYS gonna be more cases because as a responsible international player we recognise the inalienable right of our citizens to come home. As yet there is no community transmission, which means track and trace and the current managed isolation approach is working.  It may not work perfectly or forever, and it has had to be tightened - a response to evidence. But if it had been so tight initially, that people couldn't see dying relatives, that there were no compassionate allowances, then the same group of people who are jumping up and down now, would have been jumping up and down about it being an overreaction and that there was a lack of evidence of it being necessary.
    I watch social media circles on both sides of the fence, and what I see happening in NZ right now scares the hell outta me. The far left, the middle left, the "centre" and the blues and yellows on the right are all becoming a bunch of nationalistic arstholes in a fear-fed frenzy of "I'm ok mate, F**k you foreigners/travellers/other kiwis".
    Sorry this post is no longer about marine issues. But likely neither are quite a number of the posts above.

    Thought I'd start this for people to add to, then later we have all our gripes and concerns in one place so when the next revision is due...
     
     
    19.04 NAVIGATION SYSTEMS
     
    (d) Echo (Depth) Sounder
     
    Required for all categories. Seriously? For a Cat 5 race you have to have an echo sounder? Seems a little over the top... how many mullet boats have a depth sounder? Given there're plenty of small boats that don't have wiring of any sort,... How many are going to have an echo sounder? What happened to having a lead line? 
     
     
    20.0 ENGINEERING SYSTEM
     
    20.1 Installation of a propulsion engine ... 
     
    Read carefully this clause does not exclude the use of an outboard for Cat 3 or higher. And this seems to be backed up by Reg 20.13 on Outboards, which covers all categories (1 through 5).
     
    However, Reg 20.13 also states 
     
    "The outboard motor(s) must not be located near accommodation"
     
    for all categories.
    How is "near" defined? Because unless you have the outboard in a well, on a larger boat it's unlikely to meet the next part of the rule about being operated without leaning over the railing, and if you have it in a well, it's going to be near the accommodation if you have quarter berths (who doesn't?). And in a smaller boat, an outboard on the transom is also going to be "near" accommodation, simply because on a small yacht friggin EVERYTHING is near the accommodations! How is one supposed to use this rule?
     
     
    23.0 CLASSIC YACHTS
     
    Not really a gripe but more an anomaly given that NZ's fleet is not getting any younger, it appears that if you have a one-off (or two off) boat more than 50y old, you can't sail it offshore according to the Protected Objects Act 2006. So I guess all of those folk with boats from before '69 are screwed if they wanted to sail offshore...

    Yeah the compulsory ladder, while important, does have a tendency to pop open unless it's been packed away perfectly. 
    The wooden boarding ladder is something I knocked up in a hurry as a temporary fix until I can make a super light one. We decided on the boat when C was 4 months pregnant. So we got the kids and the boat at the same time, pretty much. a little difficult, but hopefully it will be worth it when we're making family holidays when the kids a little older. But it came at the cost of not buying a house...

    I can only speak on behalf of myself but I stand in awe to most other species. Humans as a collective are quite successful at being predators but this has only been the case for a vanishingly short period of our existence.
    At the individual level our brains are still those of prey not predators, hence the fear response whether rational or not to a true predator in proximity to you. I would expect to see indifference to another species in my proximity as the marker of dominance not the adrenaline fueled fight or flight response that the seal evokes.
    Progress derived from following the scientific method is likely what makes you feel so confidant to make a claim of dominance. Yet the view that you hold is not supported by scientific reasoning. Your view whether you know it or not is founded in an antiquated view made up by philosophers during the dark ages about humans being central and the purpose of nature is to serve us.
    There is no scientific basis for that rationalization and there never was. So if I should stop killing ants, swotting flies and eating meat (which I do not eat) am I now entitled to ask of you to stop using the internet, electricity and modern medicine?
     
    If the above is a bit too much all you need to know is that we have very different views of what respect for another species means and that rationalization does not lead to progress.

    Commentry:
     
    Was pretty nice weather over in Brittany, but still quite chilly in the evenings - around 9-12C in the mornings. Glad the boat has a heater (Eberspacher D4).
     
    Boat was mint. Commissioning took the best part of a week and a bit, primarily related to some custom extras taking a little longer to sort out (watermaker was faulty - hairline crack - so sent back to factory; Solar to Li battery setup somewhat tricky), me taking ages to put the child-catching netting all round the boat (what a pain in the ar$e!) and that Christina and the little one had quite bad ear infections for the whole first week which resulted in some pretty careful lounging around at the marina. Not really sailing conducive health.
     
    Consequently the first week saw a total of 2-3h sailing wherein we simply tested the functionality of all sailing systems and running gear etc. Set up the NKE AP, tested AIS etc. (now visible on Marine traffic), and read a huge pile of manuals and documentation.
     
    One thing I noticed though, is that with the Code0 and a full main, on a 12-14knt beam reach, the helm is perfectly balanced to the point of being able to let it go. The boat just tracks on not wavering - best not to fall in... 
     
    Wednesday week ago, we took our leave of St Marine (check google maps) at 11:40 and beat out up to Penmarch, 16-19knt W by WSW. Up to 8.5knts over the water just slightly cracked off (48°T) for comfort. Around Penmarch, things got a little more exciting, as the forecasted 12-14 increased to 22-27 over the deck, threw in a reef, furled the jib and changed down to the Stays'l. Bore away a touch and made for the Raz with wind about 50-55°T. Seas were relatively uncomfortable as we bucked an outgoing tide (2.5knts) pushing up to Raz-de-Sien. Slow going and although not the most comfortable weather it was also not the worst and we needed to be in Brest relatively soon, so couldn't really wait another day for perfect weather. 
     
    Wee lad succumbed to the uncomfortable ride at about 13:00, returning his lunch all over the saloon. Christina went below to take over from me, and promptly succumbed to the motion and the smell (first time ever seasick) - spent the next 8h puking... ouch...
     
    Bore away to about 120-130T going through the Raz de Sien, by now with a 1-2knt tide with us, having timed our passage to take advantage of the ebb to flood "slack". And with 22-24knts of breeze sat nicely on 12 knts boat speed sliding North to anchor for the night in Camaret-sur-Mer at about 23:00 in the very last bit of light, using our spotlight to avoid anchoring on top of any crab pots laid in the anchorage. Ryobi ONE+ spotlight, insanely powerful.
     
    Lounged around in Camaret-sur-Mer for a couple of days then caught the flood and a 10knt westerly for the 10 miles into Brest harbour where we hauled out for dry storage until mid July. 
     
    Then drove 1200km home -  never again.
     
    Notes:
    Commissioning a boat from new is hard work.  The heater is awesome. Sitting around at anchor we use about 20% battery capacity in 24h. While sailing on AP with AIS and Plotter running that goes out to 25-30% for 24h with 12h sailing. Li Battery charges from 65-100% in about 30 min motoring (enough to warm up, get out of the marina and diddle around hoisting the main for the first time. Kiddy safe netting is a pain in the butt In marinas with a lot of current and wind gusts you can NEVER have enough fenders Dodger is friggin brilliant Boat is easy to sail fast

    Not really a weekend achivement, but still some nice stuff. 
    Headed off for a week on Firefly. Best mate came in from AKL on the Saturday. Departing at 0600 on a Monday morning. Caught the high slack to go through the Raz de Sien, then down to St. Marine. On to Groix the next day and a short nip up to Lorient on the Wednesday (blowing 30 NE - and some newbies on board as well so didn't want to give them a too hard day). Thursday, Lorient back to Camaret sur Mer, 100NM with a bit of everything from 28knts Quartering (nice) to 5knt variable (also nice) and 25knts on the nose against a 4knt current (not nice). Various shots of the fun.
     
    Rounding Penmarch wing-and-wing no pole in 4knts breeze, 2.5kn boatspeed. We were all on the foredeck to lift the arse out of the water a little. Steering from my phone.

     
    Coming in to St. Marine. 

     
    Tied up in Lorient. Was fun docking with 25knt side wind.

     
    This is Pointe du Raz at 30 min past high tide. The sea is crazy there, boiling up in one place, breaking waves 100m further on, dead calm in another. The google maps shot below gives you an indication on why you really only pass through at slack tide in good weather...

    I try extremely hard to buy nothing made in China, but a few things still slip through, and it always saddens me.
     
    I preferentially buy things made in Switzerland and then The EU, even if sometimes I pay considerably more. Mostly that covers most things I need - electronics are tricky.
