Before you round any mark, it’s essential to visually locate the next mark, not only is this critical for your next-leg strategy, it will have a massive impact on how you approach each mark rounding.
As an example, at the weather mark, you must ask yourself whether you should round inside other boats so you can do a gybe set, or outside so you can do a bear away set. Having visually sighted the next mark prior to rounding will determine which approach you’lll use immediately after rounding.
The worst thing you can do tactically is
A classic mistake is not realizing that you can lay the next mark on one tack or gybe so any distance you sail away from the proper course is time and distance wasted.
If you go around the windward mark and do a bear-away set
One team member must be given this specific responsibility every time you approach a mark, their job is to locate the next mark visually while there is still time to plan your upcoming rounding and strategy for the next leg.
Once they have the mark in sight they must describe that mark’s location to the rest of the crew. They can do this by identifying a visual reference point or unique geographic feature behind the mark.
If you are sailing a set course, such as a windward and return, you can calculate a compass bearing while still on the previous leg to give the helmsperson a bearing to the next mark once rounded, this is especially important if they can’t see that mark.
Follow these mark-rounding principles and when the fleet converges at a mark you will be able to avoid the chaos that often ensues due to having a plan already mapped out.
