Hickling Broad (Norfolk UK) fitted to Seahawk 17 "C-Auk)
The Seahawk is a design of small cruising yacht built in the East of England between 1969 and 2004. About 500 were built. I was looking for the smallest practical keelboat that I might mount my wings on. For those that are interested the boat has it's own website here. The one I acquired is called "C-Auk" and is one of the last ones ever built. She is based at Whispering Reeds Boatyard. Hickling, Norfolk UK. |
Initially the boat was
set up with the smaller wing above, of only 20sq ft. Performance was as expected to be slower than when the wing was on a light beachcat. But it worked! Better in a fresh breeze, would do up to 2 knots on a broad reach. I was curious as to how well the wing would fair left permanently up. Just weathervaning in whatever breeze came along. I was pleasantly surprised that when I took it down after 16 days - I could see no sign of wear or deterioration. Next step was to set up with the extra mid section which brought the sail area up to 25 sq ft. - still very small. as below.
With this there was a
noticeable improvement in performance. Reaching (on a reach) 2.5 knots in a
fresh breeze. This was one of my aims. This meant that after you had set your course, there would be nothing to do until you reached your destination however the wind shifted. In this
configuration the rig was left up mostly unattended for 14 days.
