Theories and inventions developed by Aldis Eglajs enabled Latvia to beat the sailboat world speed record in 1982 and be the first in the soviet times to take part in the largest sailboat exhibitions and undertake sailboat export. The sail releasing arrangement of a sailing vessel has prevented all sea catamarans built in Latvia from capsizing. A modified arrangement has now been developed also for trimarans. (For more ;,,
