This past weekend I was nervous on multiple occasions. I was sailing our 12' Topper w/ my son as skipper on a port tack course. Lake runs E-W with the wind pretty much as due west at about 15 knots. perfect sailing conditions. I was extremely irritated not by the ski boats as they gave way 100% of the time but the cruisers on the lake somehow felt that their course was theirs to take and not back down. On a port tack (we were heading SW upwind) and the a cruiser heading due west but about 200 meters behind us. i noticed that our path would cross but we have the right of way so my son hel
