I did a regatta last weekend. 1.5 mile W/L courses - one start. Fleet consisted of an A2, a Hobie 20, a Formula board with 9 meter sail, and 15 other various monos (Laser, Flying Scott, MC scow, M17 scow, Thistles, etc). In every race, it was A-cat first, wind surfer 2nd, and a battle among the rest for third (both on elapsed and handicap). The a-cat and windsurfer were pretty lonely with no traffic at any of the mark roundings - the a-cat would round, then the windsurfer about 5 mins later... The conditions were B3 and B4 all weekend.
