For Filleting salmon and big browns i use a prime rib knife,get one off amazon for 12 bucks,I’ve been using the same one for over 10 years. A bit overkill for small browns, I use an aftco for them.
It’s called an e-z steer system,google them and you’ll be able to get the rest of the kit you need to complete your hookup from main motor to your kicker.
Closest would be light house marina or pine grove state launch in port Ontario if you have a small boat,best launch and what i would recommend would be to just launch at Mexico point
Don’t think port lodge takes reservations anymore,haven’t seen a truck and trailer in there in years or many vehicles at all.most likely filled with welfare people and illegals.there is a couple small cabin rental places right around there though.
If you are looking at staying in fair haven,scewie louies or anchor marina and resort,they have cabins and you can get a slip for your boat so you don’t have to launch every day.
