The 6’ beam version of the Ptarmigan 15 is quite popular and now we have extended the whole design to 17’x6’11’’. Although only 2’ longer than her sister, the Ptarmigan 17 has quite a bit more volume for larger berths and more stowage. Construction is just as simple using pre-shaped ply hull panels which are held together temporarily by wire stitches until the chine seams are epoxied. The frames and transom are again are all pre-shaped and are simply slotted into place to give the basic shape of the boat. Building is therefore quick and simple and uses the minimum of materials. She may be fitted out in a variety of ways but the standard plans show a good size of cockpit and a comfortable cabin with 2 berths and stowage for the cooker etc.
Below - the alternative yawl rig design included with the full plan set.
