my memory tells me it is not bad luck to change the name of a boat but you should keep a name plate showing its original name somewhere on board. Not sure what you do with a boat that has no name, maybe a blank plate? lol.
see a couple of days ago, a Qantas plane was landing without its landing gear down. If the on board computer had not warned them disaster would have followed.
Your day was better than what most of us had. I stared at a computer all day at work. Would have happily changed positions with you any time, fish or no fish. You will clean up next time out there.
