Hi Steve, No I have never made the sail rig for the NYMPH. It might be fun to try, but since I have the "big" M15 to use when the wind blows, the NYMPH is primarily used as a rowing machine when there is no wind...... With the longitudinal thwart - which is nice since you can change your rowing position by just sliding a bit fore or aft - it doesn't leave much space for sailing. The Bolger designed Car Topper I built had a flat bottom, so you could sit there, and lean against the sides of the boat - a very nice arrangement. For rowing you had a little box that you sat on - and which also could be moved to suit your rowing position. When sailing, I put the box up forward, and had a nice open space for sitting, with no encumbrances. ..............and Steve, the next time I build a stitch and glue boat, I'll use copper wire to hold everything in place and to insure that the alignment is proper. Trying to put sheet rock screws into 1/4" plywood is doing it the hard way! Connie
