    Yes, Bertrand is the third member of the SibLim Club, David and Marcus being the other two.  (I prefer that concept to a 'team' - I never have been a team player!)  There are several others who will be joining in the near future.  It's great.

    Now that Grand PHA has arrived in NZ, and is anchored off Norsand Boatyard, Bertrand has joined the building team, and is working on notching the bulkheads to accept the longitudinals. Just like a "barn-raising", a century or so ago, when the neighbours came to lend a hand and get the job finished quickly!

    Ho, ho, ho

    Of course it may turn out to be bigger or smaller, but  SibLim will always be the senior SibLing ...

    If anyone thinks of 'freeing ports', as I do, as a scupper with a hinged flap over it, I can assure you that SibLim will not be having these!  Just simple scuppers that allow the water to drain quickly away.

    Hi David

    I am a newbie here so I apologize in advance if my questions sound a little forward...

    I am very interested on your boat, but by being an amateur but graduated boat designer, I could not but notice a couple of interesting things on your design.

    You cant your boards 20 degrees (I Would have though that from 12 to 15 would have been more comfortable and I could not see any pinching of the same inwards) but you do not cant your rudders.

    I understand that it makes the design simpler and helps stabilize the boat while on the hard and also being rather shallow helps steer the boat, but with arrangements of this type usually you build up an asymmetrical turn on the rudders to allow for more efficient water flow ...but do you have any other reasons?

    Also, the enclose fore peak but open coamings will tend to hold a certain amount of water in bad weather, I presume that you have large scuppers to flush it out?

    thank you for your time, you have a beautiful design


    Hi Toni,

    In fact, the boards are now canted at 15 degrees, so you must be looking at an older drawing. I changed the angle to make more room for the chine logs. I haven't toed-in the board cases, as the use of Clark Y section for the boards, and resting the flat after part of that section against the cases, in itself introduces a toe-in of 2 degrees.

    The rudders aren't canted in Annie's SibLim firstly to comply with the need to "Keep It Simple, Sailor!" -  I didn't want to introduce UJs into the linkage, just simple fork, pin and eye joints; and secondly to make it easier to haul the boat down for scrubbing the bottom - an important part of Annie's plan, as she will be using copper/epoxy coating. I agree, it would be usual to cant the rudders, and I would encourage anyone else who builds a "SibLing" to cant them at 15 degrees.

    There will be freeing ports at the aft end of the foredeck, at the bottom of the fender lockers (outboard of the board cases) and at the forward end of the cockpit. These will be big enough to accept the toe of a seaboot, to act as steps to climb up from the dinghy or a pontoon.

    And make study plans available asap (I will be the first to buy them).

    And send illos and basic details to the sailing magazines, so that we might see a decent boat in these sad comics, for once ....

    No wonder "numbers are declining" (see elswhere on this thread or forum, or whatever it is called).  If you were a boat-crazy kid nowadays (as I was in the seventies) - would you really lust after one of those over-designed, under-built, two steering wheels on a thirty-two-foot wedge, brass-seacocked, identikit 'yots' with all the charm of an androgynous  dentist's waiting room? 

     

    A Siblim 32?  More power to your twin asymmetrics !!!!

    A thirty-two foot version is being drawn-up for a Kiwi couple?  I hope we will see some illustrations of this very tasty-sounding boat soon, either here or somewhere else on the website - or at least in the magazine?

    More photos here.  We are making steady, if unspectacular progress getting prepared for installing longitudinals so that we can plank up the hull.  Before most of the longitudinals can be fitted, however, we need to put the first layer on the bottom. 

    The space allowed for captions on the photographs means that they can't be too detailed.  I hope those following this build can tell what's happening from them.

    I wonder how much headroom (roughly) this 32' version would have around the companionway..?

    Edit: If Annie's SibLim is apparently 26' and has 160 cm of headroom, looking at the dxf. A 32' version if scaled equally heightwise would have 32/26*160= ~197 cm at the companionway. The scaling might not work that way in practice but it should still stop my 177 cm high head from bumping into the roof. :)

    Edit2: I'm not exactly sure what I'm after at the moment. The thing is, I might soon find myself with a decent amount of currency to spend on a boat and at first I was looking at something in the 35-40 foot range to use mainly as a liveaboard for the time being, instead of paying rent for my apartment. But for future voyages I would most likely prefer something smaller, manageable and more affordable (upkeepwise). Something like a 32' SibLim with with a minimal cockpit (just a miniscule foot well) might just be the sweet spot to provide ample space for two people. I'd just have to figure out where to build and how to find time for it.
