DESIGN BRIEF

A family vessel with a festival disposition

The Unsinkable Luau was laid down for the 26th Taft Public Library Great Cardboard Boat Race at Lake Nipmuc. Its broad beam, high sides, reinforced transom, and interior spine were selected for crew stability and the administrative comfort of the technical inspection committee.

Its yellow hull carries palm leaves, flamingos, pineapples, and a name applied at a scale visible from the opposite shore. Decorative optimism is distributed evenly to port and starboard.

YARD SPECIFICATION

Hull 26-A

The hull uses layered corrugated panels, transverse bulkheads, a longitudinal floor spine, taped structural seams, and a wide open passenger compartment. The curved transom and raised backrest provide shape without enclosing the crew.

  • Home port: Newburyport, Massachusetts
  • Builder: Capt. Dan Thistlewack
  • Construction: layered corrugated cardboard
  • Finish: tropical yellow with teal and pink livery
  • Entered regatta: 26th Taft Library Great Cardboard Boat Race
  • Builder’s stated odds of floating: Excellent

PATENTED INFLUENCE

Distributed Luau Buoyancy

The vessel is the first full-scale deployment of Thistlewack Patent TWK-CB-2026-001. Strategic tropical ornamentation is positioned around the hull to improve crew spirit without measurably reducing displacement.

The patent remains vigorously cheerful and has not been evaluated by any agency lacking a dock.
