Kite foil setup in Sri Lanka: handling sea grass, shallow lagoons, and mast lengths?

Standard Kalpitiya and Kappalady lagoons are notoriously shallow—often averaging waist-to-knee depth over sandbars—making long 85cm or 90cm carbon race masts prone to catastrophic bottom strikes. For foiling inside the main lagoon, a shorter 60cm to 65cm mast paired with a medium-aspect front wing (1000-1300 cm²) is necessary to clear submerged sand spits. If you prefer deep-water runs on an 85cm mast, launch outside the sandbar directly into the open ocean or head to the Puttalam Dutch Bay deep navigation channels where seasonal sea grass is less dense.
