TheSanibel 18 is an Americantrailerablesailboat, that was designed byCharles Ludwig, first built in 1982 and named for the Floridiantown and island.[1][2][3][4]
The boat was built by a series of different builders under several different model names in the United States, and all are now out of production.[1][4]

The series are all small recreationalkeelboats, built predominantly offiberglass, with wood trim. They havefractionalsloop rigs, transom-hungrudders and retractablecenterboards. They are normally fitted with a small 2 to 5 hp (1 to 4 kW)outboard motor for docking and maneuvering.[1][2][4]
The design has sleeping accommodation for three people, with a double"V"-berth in the bow and a straight settee in the main cabin. Cabin headroom is 54 in (137 cm).[4]
