What this is about

We live by the D'Entrecasteaux Channel in Southern Tasmania. It, and much of the Tasmanian coast, offer amazing cruising possibilities. Previously, we owned an old, sturdy and fast 33 ft Huon pine sloop that we loved. The things it didn't offer - easy portability to other waters, shoal draft, beachability and the simplicity of dinghy-like sailing - are the things we gradually craved more and more.
For at least a few years I have thought that I should build an open, or mostly open, 20-something footer that would satisfy these urges. After much looking around at designs, we finally settled on the Stir Ven.
She is beautiful, fast, seaworthy, floats in 25cm of water and is designed as an adventure boat on which one can spend a few nights.
We hope she will be ready for use by the summer of 2012/13!

building jig is ready

After much fussing around - coating all the planks and bulkheads with epoxy and building the centreboard case with all of the external battens and posts


I have finally completed the mounting all the moulds and bulkheads onto the strongback. This was a fiddly job but I may have made it worse for myself by being fussy about accuracy. I reborrowed Mike's dumpy level and checked each position along the strongback for level. Once these were levelled (a couple of spots needed shims up to 2mm thick) I was able to attach the uprights for the stations. These uprights were pine studs (90 x 35) that I ripped a true straightedge onto. I screwed these into the inside face of the two big beams at the positions that I had marked from the plans. You must make sure that you doublecheck as some measurements refer to the front of the station and some to the rear, The studs were made as plumb as possible using a tall level for accuracy.
The stations were then all placed on with the marked waterlines 800mm above the top of the strongback.
Following a great idea from Mike, I drilled a small hole (where necessary) at the intersection between the waterline mark and central axis (which I marked from the plans). This allowed me to set up a string line through all the moulds and bulkheads and check for level and centre.
Finally, I did it and feel very happy that everything is level and the boat will (or should) be straight!


I roughly cut the aft end of the stem to the bevel that will meet up with the sole and test fitted it. The pattern that I have for the keelson fit perfectly under the stem and into the slots at stations 2, 3 and 4.

Now, I have to insert the centreboard case, cut the keelson, then mount the keelson and stem (with glue) and I will be able to start planking. This is good timing as I was hoping to work on the planking during the kids school holidays  (2 weeks away) which I will be having off as well.
