Provided at a scale of 3/4" = 1'0", is an example of a typical fully assembled frame for the Bezier 28, that is located at 230 1/2" aft of the fore point. This section drawing shows the boat cut-thru the cockpit.
The various parts in the exploded view below shows the several different shapes and thickness of aluminum used to construct it. The major shapes used are 2" x 2" x 1/4" aluminum angle, 1/2" x 2" aluminum flat bar and 1/4" aluminum sheet material.
The following parts are fabricated from 2" x 2" x 1/4" aluminm angle. They require being cut to size, notched, and slotted where shown to receive the longitudinal framing.
- Part A - Side Frame
- Part C - Bottom Frame
- Part G - Cockpit Frame
- Part H - Seat Top Frame
- Part I - Seat Front Frame
- Part J - Cockpit Floor Frame
The following parts are fabricated from sheet material 1/4" thick. They will need to be cut and notched as shown.
- Part B - Bezier Curve
- Part D - Floor & Keel Member
- Part F - Coaming Frame
Part E (Deck Beams or Cabin Roof Beams) are fabricated from 2" x 1/2" flat bar. Note: Deck beams and Cabin Roof Beams will need to be cut longer than required due to the forming process. Notching and trimming would take place after forming.
Part B1 (Bezier Curve) is a roll formed part fabricated from 1/4" sheet material. It is cut to 1 3/4" x 19 1/4", and welded to Part B. This forms the bezier curved angle frame for the curved section of the hull.
The last drawing represents a sheet of paper 24" x 48". Containing the full size ptterns for the frame located at 230 1/2" aft of the fore point. Note that each part is labeled with information such as:
- Part Number
- Location at 230 1/2" aft of fore point
- Material require
- Number of piece required
- If left and right pieces are required
- If the pattern is a half pattern
