Glass fiber was patented by Owens Corning in 1935, then polyester was patented by DuPont in 1936. In 1942, a fiberglass sailing dinghy was produced for the first time using these two materials by Ray Greene (Marsh, 2006). Since then, the use of FRP in marine transportation has been increasing. The use of composites in the marine industry from the past to the present is summarized in Figure 5.1.

At each lake, PASE broadly followed the methods of Zambrano et al. (2006). In brief, pulsed direct current electric fishing equipment powered by a 1.1 KV generator and set at 50 Hz to deliver ∼1 amp was deployed from a 3 m fiberglass dinghy. A 3 m anode with a 40 cm ring was employed at a distance at which the voltage gradient was reduced to 0.12 V, representing the limit of effective galvanotaxis to the anode (Lamarque 1990), measured with a voltmeter prior to sampling. This method determined the effective area around the anode (Copp and Peñáz 1988), which ranged from 0.61 to 1.09 m2 (mean 0.95 m2) according to the standard 2-dimensional area measure adopted in quantitative fish density estimation.

Dinghy sailing can be hard physical work, depending on wind conditions, crew position and competitive level (Bojsen-Moller, Larsson, Magnusson, & Aagaard, 2007; Larsson et al., 1996; Niinimaa, Wright, Shephard, & Clarke, 1977). In moderate and high wind conditions, dinghy sailors adapt the ‘hiking’ position by leaning the upper body over the windward side of the boat (Figure 1).
