Old Town Loon 111's. We were able to purchase it years ago, but they may not be available anymore.
What makes it unique is that it came with velcro on the underside of the skirt for fitting along the side combing, where the mating half was placed to keep it on. This velcro is the 'sticky back' type, and works well. There is also a long zipper at the waistline which makes it easy to get into after putting the skirt onto the kayak. It has held up for years and though it's a nylon skirt, this boat is the one I use in the winter. (Easier to get in and out of with all the bulkier clothing I wear, plus I'm a seasoned kayaker. Think older. :) ).
If you can picture this skirt and its make-up, perhaps you could find someone who has good sewing skills and could put a zipper in and the velcro onto the sides of both the boat and skirt.
For summer and those who don't like to get 'wet', even though kayaking is a "wet" sport, we were also able to purchase two half skirts.
As noted in one of the other posts, sometimes getting wet is due to the manner in which one holds the paddle and/or whether or not there are 'drip rings' on the shaft and where they are positioned.
May you find a solution and enjoy your paddling trips.
