Retractable hulled catamaran boat

A retractable hulled catamaran boat comprising:

• (a) a central body structure having a floor structure with rising rigid port and starboard walls wherein each said walls include a passage entry opening;
• (b) parallel retractable port and starboard hulls having upright brace means to remain upright;
• (c) said hulls inboard sides having mounting means which includes a plurality of rollers (or sliders) for guided roller (or slider) mounting on said floor structure underside;
• (d) said floor structure underside characterized in that it is a smooth surface for which said mounting means rollers (or sliders) directly roll (or slide) on and/or having a system of spaced-apart transversely disposed tracks or recessed channels shaped for guiding said mounting means rollers (or sliders) to roll (or slide) on/in and further characterized in that having port side and starboard side hull span limiting stop means consisting of longitudinal lips and/or track (or channel) abutting stops for limiting spread between said mounting means so as to always be under said floor structure;
• (e) said hulls outboard sides having an upward extending hull roof consisting of a multi-planed three dimensional enclosure with fastening means for attaching longitudinally free outboard edge to associated said hulls outboard side and fastening means for attaching longitudinally free inboard edge to associated said walls;
• Whereby each said hull roof free outboard edge detaches or pivots from said hulls outboard side and free inboard edge detaches or pivots from said walls in a manner to rest on/in said central body structure thereby allowing said hull retraction and each said hulls inboard side mounted by said mounting means to said floor structure underside is guided to roll (or slide) closer together for retraction under said floor structure while share carrying above water said central body structure.

A retractable hulled catamaran boat comprising:

• (a) a central body structure having a floor structure with underside having longitudinal port and starboard perimeter lips thereon and with topside having rising rigid port and starboard walls thereon;
• (b) parallel retractable port and starboard hulls having upright brace means to remain upright;
• (c) said hulls inboard sides having mounting means which includes a plurality of rollers (or sliders) for guided roller (or slider) mounting on said floor structure underside wherein said hulls inboard sides span between said lips;
• (d) said floor structure underside characterized in that it is a smooth surface for which said mounting means rollers (or sliders) directly roll (or slide) on and/or having a system of spaced-apart transversely disposed tracks or recessed channels shaped for guiding said mounting means rollers (or sliders) to roll (or slide) on/in;
• (e) said hulls outboard sides having an upward extending hull roof consisting of a multi-planed three dimensional rigid enclosure with fastening means for attaching longitudinally free outboard edge to associated said hulls outboard side and said hull roof enclosure inboard edges angled to form a span stop so as to limit outward span and each said walls having a passage-way opening shaped to accommodate said hull roof wherein each said hull roof travels through associated said walls either before or during or after said hulls retraction or extension;
• Whereby each said hull roof retract closer together through said walls and each said hulls inboard side mounted by said mounting means to said floor structure underside is guided to roll (or slide) closer together for retraction under said floor structure while share carrying above water said central body structure.
