Finally running out of ideas, just some small stuff left:
1) If you use an intermediate rope between boom and mainsheet pulley, you can leave the mainsheet attached during harbour-furling and harbour-outfurling.
2) The foredeck on my plastic boat is mighty slippery when wet. These 3M non-slip adhesive tapes help.
3) To prevent the rowing bench from sliding while still keeping it adjustable, some Velcro pads help.
Finally, a happy sailing season to all!
