UKSA hopes to raise £10,000 in just 24 hours, as the Aberdeen Asset Management Cowes Week enters its third day.
After two days of glorious sunshine, today (Monday) threatens to be a bit bleaker with rain forecast until this evening.
The weather on the opening day of racing, Saturday, was a little too nice and favoured the shoreside rather than the events out in the water.
With not much wind, it was the cafes and shops that benefited as the crews came ashore.
Racing did manage to get underway by noon and the various classes began their week long battle.
On day two, conditions were much better, with bright sun and decent winds.
With west-south westerly wind reaching 20 knots by the afternoon and 30 degree wind shifts at times, there was plenty to challenge the competitors.
It was the Etchells racing that proved to be the most competitive, with all but the final three boats finishing within 180 seconds of each other.
Today is UKSA Day, when visitors will have the chance to try their hand at sailing, with hour long taster sessions, courtesy of the sailing charity.
Those interested should head to the UKSA stand at Cowes Yacht Haven.
The sailing charity has set the ambitious challenge of raising £10,000 in a day.
It hopes to raise the bulk of the money by selling special UKSA Aberdeen Asset Management wristbands.
The charity further hopes to raise money by sending executives up a 100ft mast attached to one of their ocean going Farrs.
The bosses will only be lowered from the towering height when they have urged all of their mobile phone contacts to pledge donations.
