The series was made of welded aluminum. Most Marinettes today are used on inland rivers and lakes, although some are found in saltwater locations. They are, due to their light weight, relatively shallow chine angle, flat transom and broad beam, relatively fast and economical for boats of their size.

Aluminum and aluminum alloys are used both in sheet form for all-metal hulls or for isolated structural members. Many sailing spars are frequently made of aluminium after 1960. It is the lightest material for building large boats (being 15–20% lighter than polyester and 30% lighter than steel).

Richard F. Smith, the designer, devised the lock notch welded system for which Charleston Dry Dock & Machine was the sole licensee. [6] The design consisted of steel plates with notches that allowed easy fit-up and welding. Only nine workmen were required to assemble the hull. This design saved one-quarter of the cost, and 85,000-lbs of rivets.
Unhardened 5086 has a yield strength of 120 MPa (17 ksi) and ultimate tensile strength of 260 MPa (38 ksi) from −28 to 100 °C (−18 to 212 °F). At cryogenic temperatures it is slightly stronger: at −196 °C (−321 °F), yield of 130 MPa (19 ksi) and ultimate tensile strength of 380 MPa (55 ksi); above 100 °C (212 °F) its strength is reduced.
The one sheet boat (OSB, cf. oriented strand board) is an outgrowth of the stitch and glue technique. The OSB is a boat that can be built using a single sheet of 4 foot by 8 foot plywood (1.22 m × 2.44 m). Some additional wood is often used, for supports, chines, or as a transom, though some can be built entirely with the sheet of plywood ...
The Thunderbird class sailboat was designed in 1958 by Seattle Washington naval architect Ben Seaborn, [1] in response to a request from the Douglas Fir Plywood Association (now APA - The Engineered Wood Association) of Tacoma, Washington for design proposals for a sailboat that would "... be both a racing and cruising boat; provide sleeping accommodations for four crew; be capable of being ...
