Female Optimist dinghy sailor Ceci Wollmann underlined her potential at the weekend.The Royal Hamilton Amateur Dinghy Club (RHADC) sailor produced a late fightback to clinch part two of Bermuda Optimist Dinghy Association’s (BODA) IODA World Championships Trial Series.Wollmann won overall honours after squeaking past reigning national Optimist champion Benn Smith on a tie-break (most bullets) after both sailors completed the series level on 34 points.Smith led the regatta for most of the series but Wollmann’s consistent sailing in variable conditions in the Great Sound at the weekend enabled her to close the gap and ultimately lay claim to top honours and bragging rights.The top five sailors following the two-part series all earned the right to fly Bermuda’s banner at July’s IODA World Championships in Italy.Chase Cooper, Mike Wollmann and Campbell Patton all secured the remaining slots available for Bermuda’s IODA World’s team that has retained the backing of sponsors Aspen Insurance Holdings Ltd.This summer’s IODA World Championships will be sailed in Riva del Garda (Lake Garda) and hosted by Fraglia Vela Riva from July 15 - 26.Part one of the BODA IODA World Championships Trial Series was held back in March.Meanwhile, last weekend's eight races also formed part one of the 2013 BODA North American Championships Trials which will determine the sailors who will qualify to sail in the event to be held here July 3 -11.Cecil Wollmann (20 pts) currently leads the North American trials followed by BODA’s 2012 Sailor of the Year Chase Cooper (21 pts), Mikey Wollmann (28 pts), Benn Smith (32 pts) and George Buckley (36 pts).The second part of North American trials are due to be held June 8-9.
