Weight reduction in performance sailing yachts, can be a tricky business. So a good rule is to take away a litle, wherever you can.
In this case, the CMP-I beam concept, where used instead of aluminum square tubes as floorboard beams.
By changing from aluminum square tubes to CMP- Ibeam concept, the weight savings can be tremendous.
In this case, 68% compared to aluminium beams
As a first step, an evaluation of the floorboard plan was done. Since unsupported spans were short and attachment points plenty, the 43x40T beam were chosen.
That also allowed as much weight savings a possible.
For this project, the customer wanted the structure precut and pre-assembled to ensure a good fit. The beams were then cut, pre-assembled, checked for structural integrity and disassembled. Then shipped to the customer for a fast and easy assembly
Type | Tot needed | Weight/m | I-Beam weight | Total weight incl, fasteners e.t.c |
---|---|---|---|---|
43x40T | 21,4m | 280g/m | 5990g | 8,07kg |
45x40 | 21,4m | 387g/m | 8280g | 11,15kg |
Aluminium 40x40x2,5 | 21,4m | 1093g/m | 23380g | 25,46kg |
Summary
From an aluminium beam weight of 25,46kg, down to an I-beam weight of totally 8,07kg, produced a massive 17,36kg´s in weight savings
Or, an average of 0,8kg/m.
