    Default Dinghy Cruising Assn UK presentation on design by John Welsford

    I was asked by the UK Dinghy Cruising Assn if I'd do a presentation on line as part of their Annual General Meeting, and was very complimented and pleased to take up the invitation. Thanks to President Roger Barnes, Jennifer Heyney, Keith Muscott and Osbert Lancaster, we used Zoom, did a couple of practice runs, and with me in New Zealand, Roger in France, and the others in UK, we got it all done, very smoothly thanks to the wonders of modern technology.

    So, for those interested, here's my thinking on the design of the open cruising boat, the "cruising dinghy".

    Thanks John I've learnt a number of things watching that and listening to you.
    You mentioned junk rigs, have you thought of designing a JR boat or adding a JR sail plan to any of your designs?

    Do you suppose his dinghy is named Maud and homeported at Littlehampton?

    Cool--thanks for sharing, John!

    If you haven't had the chance to hear John speak, don't miss it--he's really fun and entertaining, lots of smart stuff from a guy who knows and likes boats built and used by all of use amateur types. (I guess, since he has designed so many of those amateur-inspiring boats, he better know and like them!)

    You don't have to be prepared as long as you're willing to suffer the consequences.

    I've done several, I'm not averse to drawing junk rigs for my small open water cruisers, they perform pretty well, and in terms of "suitability for purpose", where that purpose is low manpower input cruising they're the best rig of all.

    I like them.

    Not one of yours unfortunately but I'm presently modifying a Bolger Cartopper to take a JR, though I don't know how it will go as I can't get the mast back the ten or so inches my calcs call for. If it doesn't work the present Leg O Mutton rig will still fit. Also adding substantial flotation both ends and either side of the centerboard case.

    Bit surprised this hasn't generated more interest.

    That was a great talk! (I readily admit that I am biased, being a Scamp enthusiast.) John Welsford has really put a lot of thought into what is needed to make a tiny boat practical and seaworthy, as well as reasonable for the average home builder. Bravo!

    Finally had time to listen to the talk and really enjoyed it. I didn't quite realize all the small things that are taken into consideration when designing a boat and how they interact.

    That is EXACTLY the impression I came away with when I got to interview John Welsford extensively for an article I was writing. So many variables to be considered in boat design! No wonder designers tend to get a bit uncomfortable when people want to change their designs...

    I can't speak for everyone, but I had to watch it over several sittings. Definitely worth it. Very interesting, as others have noted, how much thought goes into the details.

    You have that right Tom, but on the other hand I walked along a line of nine of my Navigators, no two exactly per plan, and learned a lot from the innovations and additions that the owners and builders had worked into their boats.
    I'm not so proud that I cant learn from others.

    I would guess you could narrow that down to "no one exactly to plan," eh?

    I've been eyeing up those Long Steps plans and some of the photos that are starting to appear online...
