Not to be argumentative, but I read the COREGS. If a boat is towing six long lines while trolling, what's the distinction with "limited maneuverability" of a trawler with a long or multiple long lines?
My understanding is, as most people have written above, that "sport fishing" isn't "Engaged in Fishing". However, for purposes of exploring the "authority" under the Regs, where is it clearly defined that multiple long lines didn't restrict navigation?
Of course, there are day shapes which the sailing vessel wasn't displaying; and, that fishing boat wasn't displaying the shapes anyway....
HOW MANY OF US DISPLAY SAILING DAY SHAPES? OR MOTORING DAY SHAPES?
From Rule 3 of the COREGS:
d. The term “vessel engaged in fishing” means any vessel fishing with nets, lines, trawls or other fishing apparatus which restrict manoeuvrability, but does not include a vessel fishing with trolling lines or other fishing apparatus which do not restrict manoeuvrability.
The interpretation below isn't the "REG" - I'm not sure where it's codified?
Meaning: Fishing vessels means vessels actually fishing and which due to their equipment in the water are unable to move away and keep clear of other vessels. If the fishing vessel is not fishing or is using equipment, which does not restrict their taking evasive, action for safety then they are not termed as fishing vessels. The equipment as specified under the Rules is nets, lines (long line tuna fishing), trawls or other equipment, which are similar.
