Cruise summary report
|Cruise period||2000-12-05 — 2000-12-14|
|Port of departure||Peterhead, United Kingdom|
|Port of return||Peterhead, United Kingdom|
|Objectives||Work carried out alongside Sunlight (PD 187)
1. To carry out commercial gear handling trials with centrally hinged polyamide grids (Eurogrids).
2. To obtain selectivity estimates for whitefish grids with 30 mm bar spacing and 100 mm cod-ends.
3. To obtain videofilm of deck handling procedures.
Weather conditions deteriorated and both vessels entered Lerwick on 8 December to change gear. Attempts were made to obtain a replacement board for the faulty Scanmar cabinet but without success so Illustrious was required to log grid angle data in addition to other gear performance parameters on all subsequent hauls.
