    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.

    Scott, I have to agree with David. Could you be happy with a version of Fanshi adapted for someone of greater height than Annie? I've been talking to another member about that very thing!

    Have a look in https://junkrigassociation.org/members_files drawings for Siblim 8 metre with coachroof and keel.

    update: I just heard from Frank that the build has started!

    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!

    Scott.

    Hello Scott, David Tyler will no doubt have an answer to your question. But as someone who has just completed the building of a small yacht perhaps I could also have some input. Firstly Annie has got a very good write up of her build of 'Fanshi' in the latest JRA magazine. By reading through this you will get an honest account of the difficulties experienced by a novice builder in a large boatbuilding project. People with no prior boatbuilding experience do build big boats, they learn as they go. Just as people set off to sail around the world with no sailing experience, they learn as they go. So anything is achievable if you have the persistence and perseverance. But building a 10 meter boat is going to take a very long time. It is a big boat to build, big sheets of plywood to handle. It will be thousands of hours which you need to fit into and around everything else that goes on in life.

    Any of the chined plywood boats are relatively easy to build. Probably the sharpie style hulls are the easiest. David's designs are a step up on those more simple hulls. There are a lot of considerations. A big enough space to build in. The construction of the hull. The many hours of fiberglassing and fairing and sanding. How to turn the boat the right way up. The construction of the interior. Organising the keel and the fitting of that. The rig and the fitting out. It is a massive project.

    Unless you really want to do serious offshore cruising I think that Annie's 8 meter boat is a great design. I was onboard 'Fanshi' again last week and it is a big 8 meter boat. I personally would be very happy with that size of boat, but with a raised coachroof in the saloon galley area for extra headroom in the work areas. It would be a lot less boat to build that the 10 meter version but still big enough for cruising for two people.

    I really enjoyed the build of my catamaran, and now that it is completed I find myself looking for the next boat to build, and have been considering various designs for something a bit bigger. But at the same time I am asking myself if I really want to go through all that effort again. I would really like a slightly bigger boat. But then I have have just learned of an 8 meter boat for sale locally, and which would suit my needs and ticks a lot of the boxes. it is in good condition with a lot of new equipment, and is for sale for less that the material cost of building the same boat new, so really it makes no sense for me to build again. All that time which I would spend building the boat I could be out sailing. My problem though is that I enjoy a creative project, and something to plan for. Maybe I should just build a model airplane!

    David,

    When I bought my current boat, I made a promise to myself that I would build the next one. I think I would like to build a boat around 30 feet. Since I am 6' 1" tall it would be really nice to have the standing headroom you described.

    What I am trying to say is that I am interested in this new design. I have a few things I still want to do with my current boat, but before 2025 I would like to start building a boat.

    After reading the construction section of 'The Sharpie Book' by Reuel Parker and studying some of the details of the Hogfish lines I convinced myself that building a 30-ish foot HF is something I could do.

    Can you speculate about the relative difficulty of building your design compared to a 30 foot sharpie? Do you think your plans would be suitable for a first time boat builder with very basic wood working skills?

    Scott.

    Annie, nobody could accuse you of not speaking  your mind! But in this case, you should have said " I know what I think, so don't try confusing me with facts". When I said "side decks", that does not imply a raised coachroof, in fact the shape of the whole deck over the saloon is just the same as on Fanshi. As the images show. There is no intention to sit to table on the port settee, that is principally for catnapping when singlehanded. There is ample room on the starboard settee. I initially drew the nav desk to port, but the prospective builder would prefer it next to the companionway, as would I in some ways. This is a mere detail, and does not affect the principle of the layout.

    Side decks?  Hmm.  More complexity and less flexibility with the accommodation.  There are few things more annoying than having the carlin hitting you in the back of the neck. I assume that the stowage you have shown is under these? 

    I would be inclined to put the chart table where you have shown stowage, forward of the heads, to port.  It will get incorporated into the galley far too often, where it is, and if there are electronics there, is too close to the chance of spillages to my taste.

    It will be tricky dining at the table, from the port settee and, I have to say, that one of the most wonderful things on FanShi is having a proper, walk-in cabin instead of having to post myself into bed.

    Of course, each to their own - no-one would ever accuse me of being washy-washy in my ideas about boats' accommodation!

    Indeed you do, David! More than a bit. You see what I would have/should have built in 2000, if only I'd had the experience gained between then and 2016, in 85,000 miles of sailing Tystie. Wouldn't it be great to have a time machine to export knowledge and experience backwards in time?

    I'll keep the keel end plate in mind. Makes a lot of sense for a shoal draught boat, just as it does for rudders.

    Dammit, this boat is looking so good, a lot of good features to make an excellent shallower draft purpose designed junk rig cruising yacht. I need to talk some sense into myself so I don't want to rush off and build one. The shallow draft keel is almost exactly as on 'Footprints', which gave 1 meter draft, but seemed to go to windward perfectly acceptably for a cruising yacht.

    The keel on 'Footprints' had an endplate which protruded about 100 mm either side of the keel. I always imagined that this endplate helped with leeway resistance. Now having experienced the effectiveness of the small inward facing skegs on our catamaran which essentially stop any leeway when going to windward I have no doubt that the endplate on the bottom of the keel on 'Footprints', (and 'Shoestring') present an inward facing corner which makes the shallow keel more effective when going to windward.

    Do I see a little bit of 'Tystie' in this design?
