    David, where does the outboard motor go?

    Now I've added some PDF views of the .dxf file to this folder, for those who do not have a CAD program.

    What CAD program or viewer are you using for the .dxf file, Paul?

    For the .fbm file you'll need Freeship.

    Hi David,

    In box I can only open the hydrostatics file, and not the drawings..

    is it just me?

    This project is possibly moving forward, so I've put the dxf drawing file and the Freeship file, such as they are at this stage, into Box for anyone who wants to look at them. Also an IGES file that it should be possible to import into another ship design program such as DELFTship.

    I know you've just done it, but surely it would be more sensible to buy another sound, second-hand boat and convert it?  The fact that you have just done it, would make it easier.

    Don't forget it took me over 5 years to build my boat, working full time and full days.  You would probably fit it out as David intended, in painted plywood and simple joinery (not that mine is complex by any means!), but even so ...  I know more than a few people who built a larger boat for family sailing, only to spend so long building it that the children had grown up and left home by the time it was finished

    If you really want to build a boat, then I would only encourage you.  However, you say that isn't your main reason.  Boats in USA are cheap: I'd at least look at what's available before committing myself to such a project, for all that it would be great for my boat to have sisters.

    Sorry, Scott, I have to say that I think that any boat of this size shouldn't be a first build. It needs working up to. I've been saying to people for a very long time, it seems: "first build a dinghy, then a 20ft, then you'll be ready for the 'big one' ". I let myself be persuaded in the case of Peter Manning and Malliemac, and it took him 11 years to complete a professionally built hull and deck, starting from having only a few skills and learning the rest on the job. He died, sadly, before he got any appreciable amount of payback for all his hard work. If you want to spend the rest of your life building a boat, though, just as a project, then fine, go for it. But maybe you'd be well advised to buy plans from a professional designer who offers a full "hand-holding" service throughout the build. At my age, I can't guarantee to be able to do that, through what would be at least a five year project starting in 2025. I'm not immortal!

    Thanks for the response, David.

    Mortality, specifically my own, is part of what is driving my interest in building a boat. I am over 40 now. I am sure it would have been a lot easier, physically, to build a boat at 20, or even 30 years old. I expect it will only get harder the longer I wait.

    It is pretty clear that my family is not interested in sleeping on my current boat, let alone sailing any distance. I enjoy sailing alone, but I also like to spend time with my family.

    The only way for me to ever own a sailboat that has a junk rig and is also big enough and new enough for my family to enjoy it is to build one from scratch. I guess it is possible that I could find a winning lottery ticket in my front yard, but that is not likely.

    I certainly don't want to build a boat just for the sake of building a boat the rest of my life. I want to sail.

    Does my Puddle Duck count as building a dinghy, or do I need to start all the way back at square one?

    Scott.

    Well. Scott, that would also describe me.  Although I was allowed some of what you might term the apprentice work when building Badger and China Moon, I never got to do any of the construction work and, apart from sanders (!) really didn't know how to use any of the tools, hand or electric, with any degree of skill.  What you do need to do is to work slowly and carefully and when, at three in the morning, you start wondering if you did the job well enough, go back the next day and do it again.  And yes, it will take a long time.

    My problem though is that I enjoy a creative project, and something to plan for. Maybe I should just build a model airplane!

    You are on to it David! (But here in NZ I thought we called them aeroplanes.)

    I just built 13 model dinghies and haven’t had so much fun since I got my first bike. Compared with something bigger, they take no time at all!

    Scott- here’s how it goes. You set up your frames and bulkheads, and think “wow – this is not going to take long at all”. You plank it up, and think “wow, I’ve almost finished building a boat and it only took me less than a year”.

    Then the hard work starts. And that’s where many of these projects stall.

    A sharpie hull will be somewhat easier to build than a SIBLIM. But the hard thing is this: thinking and worrying about building the hull is not seeing the big picture. Building the hull is not half, maybe not even a quarter of what it takes to build a complete boat.

    Annie's blog describes brilliantly not just the creative process, but also the difficulties and the "hard yards" - which grow to the power of three as a function of length.

    [Here's a little maths lesson. 8m to the power of three is 512. Compare with 10m to the power of three which is 1,000.  It is tempting to think "All that work to build an 8m boat, why not just make it just a couple more metres and get so much more accommodation etc..." Yeah, right. You will certainly get much more. And the increase in time and cost will be roughly in the proportion of 1,000 compared with 512. About twice as much.]

    The designer of SIBLIM says “first build a dinghy” and I would agree – and take it further by suggesting you buy yourself a sheet of 3mm ply and first build a model of your dream 10m vessel. It will take you only a couple of days to build the hull (that shows how much size really does matter) and you will learn a great deal from that. Leave the deck off – sand it and paint it, and do a little improvised interior. That will take you a bit more than a couple of days, but still not long, and you will begin to get some perspective – and inspiration too.

    I think David and Annie commenced Fanshi by building a model - I came across it, left behind unwanted, in the shed, after Annie’s launching. I thought it was a lovely little thing and badly wanted to take it home with me but had nowhere to keep it.

    I wonder what happened to it?

    Build a model first. Build a model sharpie and a model SIBLIM and then you will soon see that SIBLIM is not such an easy build – but you will also see that building the hull is, anyway,  only the first step in the process. In the end you won't save much merely by building the simplest - but you will save much by building the smallest.

    The suggestion of a model is not to discourage. It will inspire.
