Lost Bouys!!!

Its been a pretty interesting day on the water today. The visibility again was pretty poor, down to around 80m at times. We headed out to sea to do some short course racing. Chris laid a course and gps marked the buoy positions. After we rounded the windward mark we headed back down wind on a compass bearing, neither of us could find the buoys so Chris motored to the gps position and they werent there!!! After a few minutes looking we gave up and decided to do some speed work.
May be well find them tomorrow?????
