page_txt=Designed by: Nathanael Herreshoff The Marlin is a wonderful midsize keel sloop when you want the accommodations of cabin space without a full cruising boat. The Marlin is offered in a day sailing version with plenty of cockpit space and a smaller cabin and a cruising version with more cabin space and a self bailing cockpit. Being enlarged from the H-12 1/2 design, both versions deliver the performance you expect from a Captain Nat design.
