As am owner/operator, I wish you the best of luck. However, a full guided day can be had for a few dollars more. That being said, I can see a few guys not wanting to be guided, but I can think of two "self guided" outfits with hands on operators that didn't work as the price spread between guided and self guided was very slim. Liabilities I can see being a headache, but Pedder Bay seems to do just fine. You can get a day off Victoria for $600 if you look around (And some of "those" guys do get fish)
You have a really nice boat. Hopefully it stays that way. I know a pro who had his buddy running his rig while he tied gear. Guy saw a log, and stabbed it into reverse at 20MPH. Money grew wings, and Big Bill came by for a visit.
But if it works, you'll be looking smart with your boat paying you to use it. However, the success rate of bare rental fishing boats has been very poor, (Quigley, Luckey), but Pedder Bay seems to make it work. Very simple boats.
