Last year 133 boats and their crews took part, and event organiser Clyde Cruising Club is hoping to beat this figure in 2011, encouraging sailors thinking about entering to sign up while the early bird discount is available.
Johnnie Readman, event organiser, said "Last year's event was a huge success and I have no doubt that this year's competition will be even more fun.
"We have introduced a number of changes this year in order to offer variety and encourage more entries from the UK and abroad. The changes include new courses and variations for all fleets, the introduction of a short Inshore Coastal race for IRC classes, some shore based starts for the CYCA classes, and replacement of the IRC sportsboats handicap starts with One Design class starts.
"We would encourage all sailors interested in coming along to sign up as soon as possible."
The 2011 Brewin Dolphin Scottish Series takes place during the bank holiday weekend from Friday 27 to Monday 30 May in Tarbert on Scotland's stunning West Coast.
