When it comes to the cost of your next sailing trip and whether you can share a boat, it usually depends on a number of factors, such as the location of the trip, the type of boat, the nature of the trip, etc. Specific cost information needs to be obtained by contacting the agency that provides overseas services. As for boat sharing, whether it is feasible also needs to be determined based on the capacity of the ship and the number of existing passengers at the time. It is recommended that you contact the relevant agency directly for more information.
