Remarks:In sub Nav was invaluable for mapping & sampling when coupled with a sea beam base map & grided X-Y co-ords. Excellent sampling, cruising, power conservation by Pat. Pat was also able to backtrack & collect specific samples and was receptive to our difficult requests. Excellent dust-pan technique
