Objectives | The objective of this cruise was to evaluate the performance of several types of otterboard. The same net (30 ft Aberdeen with double sweep) was used on all tests to establish a common basis for the results and tests were carried out on the following types of otterboard:
A) conventional flat boards.
B) 'V' boards. There were four attachment points available for connecting the towing warp to the boards, and tests were carried out with all of these.
C) Cambered boards.
D) "Fibreglass" flat boards. These were of a novel design, having a metal keel and frame as for type (a) but with the body made of fibreglass with a chipboard centre. |
