Could the leak be a pinhole in the cylinder liner, that would explain the head crack testing all good. Had a volvo md2 do that years ago.

Thanks to SSANZ for running a great series. Didn't get any video of our race but had a blinder of a trip home that some may enjoy.

You shouldn't have to reinforce anything for a 2 blade, while generally not quite as smooth as a 3 blade prop unless they have had a shocker with the balancing it will be acceptable.

Have used both Kiwi props and Two blade folders. For a racing yacht I would go for a geared folder.
For mostly cruising I would go with Kiwiprop.
I have always found the Kiwiprop guy very helpful.
We are now on our third keeler with a Kiwiprop. You have to be aware if they get dirty they can really load up in reverse I have found you need to get the revs up quickly soon after engaging reverse gear. For reversing and maneuvering the boat when there is a bit on they are very good.
A two blade folder will often struggle to reverse into a bit of wind and chop.

Good call. See what the weather brings. Burning lots of diesel out here at the moment. See you Saturday.

Rogue sailing down the coast of Puerto Rico.
Nice to see the cruising boat has the full Booboo style gennaker. No mucking around.

Have found the spinlock range pretty good. If it's highly loaded like the main halyard we usually put them on a which to release just to look after the clutch but they will still release ok of we are in a hurry. I wouldn't expect as much load on a Vang mind you.

Search suspended not looking good unfortunately.

max speed was over 27 knots. Do you not think that is sufficient to cause an issue? It wont slip sideways well, with the stub keels. If it does round up for whatever reason, they are in trouble. IMO.
Ha missed the 27 knots only saw high teens when I first looked. I still don't think there was any risk of broaching as long as the boat is going faster than the waves steering will be well controlled, it's when the waves overtake the boat that the sh*t starts to happen in my experience. I don't think the seaway they were in warranted anything to be concerned about.
I have have sailed a C36 through cook straight in 50+ knots, double reefed main only with no drama at all never even looked like broaching. I couldn't see the waves very well because it was dark but our top speed was over 14 knots, on a 8 tonne IOR design that means freakin huge waves. Even with a kite up in 30 knots we had never been over 10 knots before. Speed is good up until it isn't.

For someone used to a raked bow I imagine the Lagoon would look close to the edge but I don't think it was. It is a 50ft plus boat with plumb bows. The waves weren't big enough to lift the stern much and the speeds in the glimpses of the nav gear weren't very high.
Our boat (not a multihull) with plumb bow has water over the front pretty much constantly once we get over about 13 knots, even in flat water.

I usually use Tef Gel, it is available at most marine shops there are similar alternatives.

Whatever, its up to each skipper to manage risk and if you happen to comfortable in pushing a cruising multi downhill in those conditions then good for you.
Hmm don't remember saying that. Off your meds today?

Looked like a dream run to me, 50 knots is easy if you are running with it and don't have to much rag up. Yes the bows were pressed a bit wounder how deep reefed the were. They could have gone bare poles if the wind kept increasing. But as those cats are usually fully battened mains might not have been easy to get down.
The waves were fairly small suggesting they were reasonably close to land .

Yep good on him for realising the inevitable.

Do not use Nylon as a bearing material. It will expand underwater and seize the bearing and steering...
I thought people stopped using that in the 80's.
This is the stuff.

High Pressure & Marine Bearings
Contact us for our comprehensive ACM Composite Bearing design manuals for general and marine engineering.
ACM Composite Bearings are premium high pressure bearing materials. They offer engineers cost effective alternatives to phosphor bronze, with many advantages over phosphor bronze and older traditional bearing materials sometimes used in its place.
ACM TriboTex 7 for general purpose engineering applications.
ACM TriboGlide 15 for low friction, dry running applications.
ACM TriboTape for guide bands in hydraulic cylinders.
ACM L2 Marine grade has multiple marine class approvals for use as ship rudder bearings and water lubricated propeller shaft bearings.

These Guys made ours if you can't find anywhere closer to home, quite a few boats around here have used them.

That looks not dissimilar to the process they use for 3di sails. I wonder if that's where Norths got the idea.

Brunel trying to get past Mapfre. Match racing in 30 knots of breeze in the North Sea.

Hell yes good stuff.

Scubash used to do it. Not sure if she still does.

If you read old pilot books, what is now Stewart Island was called the south Island and what we call the south Island was called the middle Island.

The rudders are huge.
He's done a sh*t load more than most of us so who am I to judge.

Compulsory licensing isn't going to fix stupid. Plenty of idiots with licenses on the road.
