Ralph Hoehn: ... Chris Kulczicki's "Yare" ... reputation for relatively low stability and a wet ride ... Alex Ferguson: But what a good boat for increasing skills. RH: Indeed it is!! The fact that I moved the sheer clamps outboard of the hull skin while keeping the design beam at the sheer -- originally intended merely to allow me to attach the deck with no mechanical fasteners -- has meant that the boat is even less stable than designed (narrower waterline beam on an even closer to semi-circular submerged cross-section). In this configuration the sheer clamps also knock down waves and spray AND slow the roll to a very deliberate pace ... no use hoping for help from the momentum of the roll and a strong hip flick here to get back up on an even keel. I sit directly on the hull skin to keep the center of gravity as low as possible. The curvature of the hull is severe enough to compress the gluteus maximus to the point where the lower ends of the pelvic bones are cushioned and I find this seating position quite comfortable for extended periods without losing feeling in my legs.

With mine, I put in a keelson as per the Skua 16 in Sea Kayaker magazine, added about 10 degrees deadrise and made the beam as narrow as it would go without rising the middle higher than the ends. There is also a "proper" bow to bring the length up to 5 metres and keep some flare right out to the end of the bow. The stern also carries its depth a little more with a transom for fitting a rudder to (adds just a little more flare there too). >RH - >I sit directly on the hull skin to keep the center of gravity as low as >possible.

With the deadrise I'm at least an inch if not more, maybe 2, above the very bottom of the keel on the foam seat. With rudder and ready for sea - 18 kg (39 lb). Fast - very; tippy - very; loaded for multiday tripping - stable with a lovely easy motion. Alex . .

So why did CLC drop the Yare design? Other than the fact that even the crew at the CLC shop was usually hard pressed to avoid building knuckles into the transitions from round bottom midsection to the V-shaped ends ...

Two ways to get round that - make a "funny" shaped keel line on the two planks or "fill it in". I used the latter method, adding 3 mm of ply along the "hollow" and grinding/fairing it back to a straight line keel. Alex . .

R: ... even the crew at the CLC shop was usually hard pressed to avoid building knuckles into the transitions from round bottom midsection to the V-shaped ends ... A: Two ways to get round that - make a "funny" shaped keel line on the two planks or "fill it in". I used the latter method, adding 3 mm of ply along the "hollow" and grinding/fairing it back to a straight line keel. R: I used a bit of a combination of both ... after the fact. Using my trusty circular saw to do some free hand carving (don't try this at home, kids!!) I opened up the seam at the keel line in the region of the offensive knuckle and then pulled the sides further in. You can only go so far this way because you do run up against the limitations of "torturing" the plywood. So the rest was fill and grind, but actually very little of the latter was required in the end. Now that we've finished boring the rest of the PaddleWisenheimers to tears ...
