Just getting ready to order a new main and 150 for my Catalina 22. They will both be tri radial Dacron and I am debating on adding vision window(s) to the head sail. I race some in PHRF on a busy lake with floating debris on the Mississippi and I am wondering if the window will help me see obstacles and other boats or just fog over with spray and be useless. The 150 on my boat is a deck sweeper so the only way to see around it is to look behind it from the leeward side which can shift weight and be a challenge if I am single handed for a day of fun on the water.
