Hey ho. What luck to see your post -- I rarely visit SailNet these days. We did not buy the E20 -- went with the SJ21 instead. Much livelier boat, but it has its own challenges. We did have some folks roll into Isthmus Cove (Catalina Island) this summer on an E20 and tie off to the stringline: brand new sailors on their first trip anywhere, and the boat took care of them on the crossing. Also the only boat we've ever seen at Catalina smaller than ours -- tho rather heavier!
For E20 information, you might peruse these sites:
Rick's Sailing pages
And don't forget to search for the RK20 and Balboa 20 versions of the boat. Or go to the Trailer Sailor BBS and ask for Rick or Noemi, both of whom sail the E20. Rick did a multi-day in the Apostle Islands this summer.
, the E20 uses your basic boom-end triangular mainsheet setup: Sheet attaches to a becket on one coaming block; over the bottom sheave on the boom end fiddle block; down and around the other coaming block; back over the boom-end fiddle, top sheave; down and around the first coaming block, and thence to a cleat on the cockpit sole. Our SJ21 was set up the same, tho we have since changed to mid-boom sheeting.
