Whether you plan to navigate along the coast or sail around the world, the length of your yacht is an important factor to consider. Based on a given number of cabins, a liveaboard sailboat’s size usually varies upon the overall space that is desired.
To have the most comfortable cruising sailboat, this extra space can be alternatively used to:
In general, the size of your liveaboard sailboat will depend on what you are looking for in a yacht: your comfort requirements, the amount of equipment embarked, the number of people who are going to be living on board, etc. If you are a solo sailor, you might feel comfortable on a 30-foot yacht but will probably prefer a larger sailing boat if you are traveling as a family (32 ft, 35 ft, 40ft, or more).
RM Yachts, which are all plywood monohull sailboats, are lighter than any given other yacht of equivalent size, built with other materials.
Consequently, they enable the owner to better balance the overall weight of equipment required for a specific navigation plan: coastal cruising, port-hopping, ocean cruising, blue water cruising, sabbatical journey, circumnavigation, etc.
Beyond equipment and comfort, the size of a yacht also has an impact on her motion at sea, her seaworthiness, and her global performance: a hull with a great beam will bring more space (hence more comfort for day-to-day living) but will also be stiffer and powerful (hence higher performance and greater ability to start planning)
RM Yachts hull design, inspired by offshore racers, is well-known for their shape and lines. Their reverse bow increases the LWL.
Taking into account the LWL has an impact on hull speed, that can be calculated as following:
Hull speed: 2,43 x LWL (Length at Water Line)
