    Morris 29 in SFO

    Actually it's the Morris 36 that was the first boat in the line, and is inspired by an old S&S design. The M29 and larger boats in the line are variants of the M29. That said, I agree that the M29 it's the best looking - one of the benefits of not trying to fit in much of an interior.

    1,900 containers into the Pacific

    Annual average is just the average of the annual total over the years stated?

    ePropulsion Pod Drive

    For a company selling themselves as a high tech, top end product, why do they make their throttle controls look like something off of a '90s game console? The top mount in particular I think I'd be embarrassed to have on my boat.

    Dylan's New Boat Anarchy

    You also see thirds method used in parts of Cornwall - not just for quay walls, but also for low retaining walls alongside roads, forming terraces in sloping gardens etc. The land based uses implies it's not used due to washout of material under wave action. Walls built like this all seem to have relatively crudely cut stones I.e. not cut with perfectly flat faces. I did wonder whether this method let's you get away with this, and so save time (cutting stones to shape by hand being much slower than actually laying the stones). By laying the stones vertically, their weight wedges them in place between the adjacent courses. Where's if laying horizontally, without the use of a lot of relatively stiff mortar imperfectly cut stones with slightly slipping top or bottom faces would tend to slide off of one another.

    1,900 containers into the Pacific

    No, we didn't have radar. But one of them was in the middle of the Solent, in an area well covered by Southampton VTS (the port's vessel control service). When we reported the container they confirmed that they couldn't see it on their radar. If their powerful, high tech radars can't see a container, in pretty flat water, I doubt we would have done on small yacht radar. The fact that it was in the Solent is also scary - I doubt a container has ever been lost in the Solent, and very rarely in the English channel - weather just isn't bad enough. So this bright red 20 foot container must have drifted hundreds of miles through some very busy waters without being spotted till we did. Still, I take the view that despite the number of containers lost (which is awful for environmental reasons) the risk of hitting one remains very small (Ok, I've seen two, but would have missed both. I've only meet one other person who has spotted one). I figure we accept much higher risks on a daily basis - driving, using stairs, going out in direct sunlight, eating fatty food etc.

    False. Packing foam can take a surprising amount of pressure. I use higher quality versions of the same stuff to provide bounce buoyancy in some very deep draft pontoons - up to 4m draught, subject to a further couple of meters of head pressure in extreme bad weather. And its good for 50 years of use. I suspect the poorer quality materials used in packing foam is still good for quite a bit of cyclic water pressure. I've sailed past two floating containers - despite relatively benign conditions and good daylight, weeing both cases we only spotted them at the last minute as they were floating with their upper face awash - maybe 50mm - 100mm freeboard, but remaining consistently lower than the crests of the small waves, so impossible to see from a distance, and so presumably also invisible to radar.

    H-Boat vs. Hinckley Sou'wester 30

    Or just get a boatyard to install an outboard motor well under the tiller. When I spent a couple of summers sailing the Baltic I saw a couple of H- boats that had done this. Probably a lot cheaper than the other options, if not quite as polished.

    I can see how he ended up in that wheelchair! In that video he shoots out into the road without looking left or right. Most mobility scooter drivers seem to come from the same school of road safety.

    "Pioneer"

    Good point. I had in my mind that they were only available in 100hp plus models. But I see that there is now a 50hp diesel outboard on the market. Hopefully in time they'll get down to diesel outboards in the 15 - 30hp range. Then the only issue with outboard will be the inability to sound insulate them! I struggle with loud, continuous background noise, to the point where on my last boat, which was outboard powered, I took to wearing earplugs when on passage under motor. Definately takes away some of the pleasure of being on the water (But on the plus side, motivates you to get sailing as soon as there is the slightest puff off wind)

    Don't know what it's like in north America, but in the UK fewer and fewer fuel barges and marinas are supplying petrol any more. It's one thing walking to the nearest car fuel station and back with fuel for a 6hp motor on a small cruising yacht, whilst with a RIB you can fetch the fuel in your car. But carrying enough fuel by hand for a large yacht when you're off cruising doesn't sound much fun. Pity, because otherwise outboards make a lot of sense. Especially if mounted as on the Swallow Yachts Coast 250.

    Dylan's New Boat Anarchy

    I've sailed on and off for 20 years on the UK south and east coast, Scotland, North sea and Baltic. In all that time there's only been two occasions where I wished I had radar (and even then it was more a 'nice to have' rather than 'must have'). All other times caught in fog or poor visibility there has been no pressing need for radar. Yes, sometimes I changed my plans (e.g. alternate destination) or changed my route (get inshore into shallow waters) but isn't that what sailings about. Radar, chart plotters etc. cost money. I've never owned a boat bigger than 24 foot or worth more than £5,000. But I've sailed further than many cruisers do in a boat twice the size (UK - Estonia and back, circumnavigation of the UK etc. If iId had to spend money on radar etc. I probably wouldn't have gone. My interpretation of Dylan's spending habits is that he's of a similar view (Sorry Dylan for making assumptions on your behalf!)

    DSS Foil Why did Wild Oats stop using it?

    It's not a matter of context. 'An order of magnitude' has a very well defined that is not changed by the context it is used in. What you're saying is makes as much sense as claiming that it's correct to say that a yacht that increases it's speed from 5 knots to 6 knots had tripled its speed, because of the context in which it's stated.
  13. Except where ever I've said 'centre of gravity' it should read 'centre of bouyancy'. Not sure why I can't edit my post.
  14. It's not the distance between the ballast that's important - is the horizontal distance at the angle of heel you're considering. So let's say for simplicity that when the hull is upright the crew are 2 meters horizontally or from the centre of gravity, and the keel is 2m directly below the centre of gravity. So when upright 100kg of crew provide 2 kNm of righting moment (2m x 0.1tonnes x 10m/s) and the keel provides zero righting moment. A typical sailing angle might be 15 degrees. So 100kg of crew provide 2 x cos15 x 0.1 x 10 = 1.93 kNm of righting moment, 100kg of keel ballast provides 2 x sin15 x 0.1 x 10 = 0.52 kNm of righting moment. So in this case, you need 400kg of ballast to replace 100kg of crew at 15 degrees of heel.

    34-40 ft Cruiser Racer for 6-8 People

    You state that you want a cruiser/racer, then list three boats that are very much coastal cruisers / marina holiday homes. I think you need to clarify what you really want (both to yourself and the forum) if you want useful suggestions - just now you're getting suggestions that range from racers with a bit of accommodation through to yachts that can barely get out of their own way. Your annual maintenance budget also seems somewhat optimistic for a yacht of this size. Might get away with paying that little some years, but others are going to be way more expensive.
