Hi Salmon Fisher and welcome.
Congratulations for you and your mate on retiring - so much more freedom and more time for fishing
I can't answer your Q's, as I don't own a boat etc, but I'm sure - well hopefully - someone can put you onto some nice spots for those KG's.
As far as Salmon Trout is concerned, I reckon you could throw some metals around while your anchored in different spot - many are around at the moment. Throw a lure out the back on your way out and maybe some bigger Salmon come to play.
Good Luck and if you get some good outings, we'd love to hear about i
