Field notes
The map description names Lake Mikołajskie, the town of Mikołajki, Lake Tałty, marinas, forest shoreline, and the red and green buoys marking real positions. Four selectable boats are modeled on named craft, from an open Omega-style dinghy to a Maxus 33-style cruiser. The site says other sailors share the water, wind, and time of day; phone play is not supported.
