Yup.... definately a Gem Micro.... another innovative design at the time by Rob Humphreys...... designed to be a trailer sailer with lifting keel and remember seeing the first ones being built in Lymington in the 70's if I remember right, by Steve Wolfe, John Pearce and the rest of the Lymington farmyard builders if memory serves.... Seem to remember John Claridge being involved in some way at the time as well.....
