We are planning on BVI vacation for June 2018! We currently have on hold a 2015 480 “Sail” Catamaran. Group of 8 people (5 experienced boaters - we own boats that we use on lakes but zero sailing experience). Since booking part of our group has become very uneasy about boat selection given boat only has twin 45HP diesel engines. Travel agent assures us this is enough power to safely navigate. We are used to boating on boats with 800-1000HP. Since we have no sailing experience could you safely travel around BVI’s in a sail cat not using sails? Any insight is appreciated! Thank you!
