Booklet | Manual30 миль РУСФИН / 30 miles RUSFIN
"The goal of our project is to repeat the success of similar cooperation between Finland and Estonia, when rings of small ports appeared every 30 miles around the Gulf of Finland. A distance of 30 miles (about 50 km) is considered optimal for tourist yachts, since at an average speed of 5-6 knots it allows you to pass this distance in a day of travel " Kovalev S. N.
