Abstract
Abstract A sailboat with an inflatable compartment defining a hull and having a plurality of interconnected tubular members forming a support structure for a mast. A plurality of brackets are mounted to the hull for captively holding the tubular members in a substantially A-frame configuration. A sail is connected to the mast which is captively held to the support structure and hull.
