Triskel Marine has launched their new website for their Integrel generator replacement. Here's a couple of videos of Nigel Calder talking about the technology behind it, one long and one short.

Another thing to consider is where you want to sail most often and the time to get there. Many years ago we shifted from Half Moon Bay to Pine Harbour even though HMB was only a few minutes down the road as the total time to get to the bottom end, Noisies, etc. was much better from Pine Harbour even including the drive out to PH. Think about where you want to sail most and how long the drive is if you want to duck down to the boat to do work on it.

Interesting to see that Colligo Marine are offering 3D print files of their new Revolution blocks so you can buy the blocks or buy the components and print your own blocks. I've been wondering when this would start to become more common for a number of components with the rise of more accessible desktop CNC machines, 3D printers and laser cutters. Who else is doing this?

I read the digital versions from the library which lets me access them for free anywhere in the world. The Auckland library has Practical Boat Owner, Sail, Yachting Monthly, Classic Boat, Yachting World and Sailing Today as well as Boating NZ in digital format.

If the coolant rises before the engine is warm it would suggest air in the system so to me in my limited experience either the coolant needs bleeding or as you suggest it's coming from a combustion gas leak.

You could try removing the water distribution pipe from the cylinder head and clean it with muriatic acid along with the exhaust elbow, the heat exchanger, and other associated cooling pipes to remove any deposits that have built up. Even if there's flow it may not be working as it should as the build-up on the surfaces can impact heat transfer which reduces the cooling effectiveness.

That's great Puff but not everyone has the same level of ability and imagine if everyone was forced to sail that way? Would you still sail? Wouldn't you want access to a better design if you could have it? Good design doesn't always have to cost a lot or even anymore, it can just be about having more awareness of others needs and incorporating them from the beginning. Retrofitting is where things can get really expensive. This is not to say that everything must be designed for use by everybody as there will always be a need for more specialised use but we can do a lot better in general if we want to.
Think housing, around 60% of households will have a person with a disability in them at some stage given that almost a quarter of the population has some form of disability due to birth defects, illness, injury and ageing. It is around twenty-two times more cost efficient to include accessibility features in the initial build than it is to retrofit them later yet most house design has never taken this into account. How often do we curse the bad design of the things around us or that we use when it doesn't have to be that way? Now add some form of disability into the mix and think how much worse things might be. We need to stop just thinking about what works for us as individuals right now and think more about what might make things better for us and others in the future as well. Hopping off my soapbox now.

It's all about options. I've all my abilities (well some may question that) but I have sailed and raced Hansa Class boats with those of all abilities and they're great little boats but this opens up bluewater cruising and racing with autonomy because the design is inclusive, not exclusive. We too often design our world without a thought for accessibility for all members of society (this can be physical, regulatory, etc.) and this is an example of how we can do things better in all areas of life if we are aware and we want to.

Apparently, the Pudgy rows well enough but its weight doesn't do it any favours when it comes to sailing in light airs. That said I can't see why it or similar craft shouldn't be made an allowable option to liferafts for the single or short handed cruising yacht. Especially given the less than 100% success rate of liferaft launches.
-
Need more boats like this that create the opportunity for access to sailing for those who normally don't get the chance.

Sounds like some seriously strong wood might be on the horizon. Wooden boat anyone?

I looked at the Newick traveller 52 ft that used to be at westhaven, great long distance sailer but not much room at all inside , and the 36 is pretty cramped.
The Neel 51 has plenty of room inside.

I thought this video had some good and practical medical advice for dealing with some common medical emergencies on a boat.

Note to self:
Replace newwly installed blue spreader floods with red.....nah, can't do that as might be seen from strbd.
ah, back to white. to hell with nite vision.
For the greater good................

Modern diesels using modern lubricants are pretty good with respect to glazing but even so long periods at idle can be a problem, even if less common than in the past but turning the prop should create enough load. Ideally, the engine should be given a burst of max throttle every couple of hours or so. Proper running in and using the correct lubricants has a big impact on reducing potential glazing and it shouldn't be run with no/minimal load for extended periods within the first 100 hours.

I saw that too when I was looking last night so I just went to their site. Bit of a fail though.

I was having a look at NIWA's bathymetry section the other day. Big file sizes. https://www.niwa.co.nz/our-science/oceans/bathymetry

In similar situations, I have sent a cheque and written on the back that this is accepted as full and final payment for invoice #xxxx figuring that if they bank it then they have accepted the condition. Never had a problem with it so far. Worth a shot?

40m is fine on air if you know what you're doing. Mixed gas would be better but not necessary for a quick inspection but I understand their need to follow strict rules, it keeps them safe. Worst job I ever did was a salvage on a boat that went down with a family on it. Never want to dive where bodies are involved ever again, having grieving relatives around only made it worse. The police divers earn their money.

What's the noise level like for diesel outboards?
