The followup on this project is that my DK17 is one of 4 DK's launched this year.

I raced twice in Bristol RI with the Acat fleet at the very beginning of the season. My first outing I capsized 4 or 5 times while tacking. I kept getting caught up in the midboom sheeting. The second outing I faired better, I wrapped a scrap of sail material around the boom as a way to keep getting caught in the sheet. I didnt come close to the veterans... These guys are fast. Its not the boat, by the way, its the sailor. In June, work kicked into high gear and I wasnt able to make any more Tuesday night races. I cant believe its almost the end of the year and I only raced this thing twice.

I did sail it regularly on the LIS out of New Haven, no major issues, no major breakages. I am still learing how to go downwind and thats going to take some practice.

I'm planning on attending the Jan regatta in FL, they are forecasting 50 boats.

I did have a couple issues with the tramp attachment, I used a plastic mast and slugs in a track to loop into and tighten the tramp. The plastic track failed, it wasnt stiff enough to hold my weight, so I think that I'll just add some carbon tabs and knot some spectra loops in it.

Other than the tramp track its been great. Its still underweight so this winter I might add some wings - the hulls are canted in, and I could add 2-3 inch wings at the deck so that I could trap out at max beam.

The only other thing, is that i'm not sold on the midboom sheeting, but I'm not going to change it right away.
