Thank you. It's arrived safely and is exactly as described.

That particular corner isn't very appealing, but it's not typical of the place as a whole. But 'care in the community' has presented society with all sorts of challenges. I'm sure lot's on here would love to see the council move in, bulldoze it all into a bonfire and ship the owner off to some...

Jim Leishman talks quite amusingly about the arguments they had when planning the first Nordhavens about how much 'space' should be allocated to machinery. Suffice to say, prioritising accommodation won the day and is probably why they have sold so well. But there are times when the...

Well that's not a bad correlation - 700°C is 973°K and 22 1/2 or 24 cu m/min is near enough! I think you can assume the exhaust volume isn't 7.2 cu m/min

When it's big enough that you can afford to have paid crew. "Hey you! Fix the float switch" Bingo, job done.

Really? Your confidence in welded stainless steel in what, is essentially an oxygen free environment, is much greater than mine. Especially in boats that have been in warm (Med / Tropical) water. Rudders can be split, inspected and have their stainless parts epoxy coated before being...

Plus temperature expansion: Use an ambient Temperature of 300°k and I'm sure diesel exhaust gases in a dry stack at full chat run to 1000°K. = 12 litres. = 24 m3/min

Well it does if it was simply running on the starter motor and acting as an air pump. But to the air intake volume (assuming no turbo) you also add a certain amount of diesel which when combusted turns into a considerable amount of extra gas. It's also hot, so every is expanded.

Not really, but have fitted dozens to our new build expedition yachts over the last 25 years and out tests showed they do shift water!

These are the only emergency bilge pumps I've seen that have the reliability and discharge rate to make a difference. They've been around for at least 25 years to my knowledge and shift water like a fire hose. http://www.yachtwork.com/product-bilge.htm

But don't get your hopes up that you're going to get a complete cockpit on the cheap. They take a lot of material and a hell of a lot of work (and risk as they're complex and difficult to get 'perfect').

I would recommend you look out for a copy of 'Heart of Glass' by Dan Spurr (International Marine / McGraw-Hill ). It's a history of the early years of composite boatbuilding. It recounts the use of all sorts of reinforcing material before glass became ubiquitous. Just of fascinating is...

The high temperature exhaust manifold configuration will be dictated by the shape of the outlet ports on the head. And the head will be the same shape on all engines. So a gasket from http://www.parts4engines.com/perkins-4-99-4-107-4-108-exhaust-manifold-gaskets/ should work.

Have a look on the DMM Climbing Equipment website and see their demonstration of 2 ton Spectra webbing slings (same as dyneema) snapping when a human size weight drops a few feet onto it. The warning is there for primarily climbers and those working at height. But essentially there can't be a...
