I used to have a Boston Whaler Montauk and caught and cooked (and smoked) many salmon.
I have a Little Chief just for cold smoking.
Personally for fresh salmon, I prefer baking the salmon filets, as described below.
Filet as described above.
Soak alder chips to a water pan.
Place the salmon filet in an oiled foil pan (or you can make one).
In a pot add butter, mustard, worchester, lemon, brown sugar, and minced garlic or ginger. Heat and bring to liquid stage and baste the filet with this mixture.
Cover the filet with thinly sliced lemons
Add to a grill/kettle that is 350+- degrees, with indirect heat. Add the alder chips over the coals.
After 20 minutes start checking for doneness by lightly pushing down on the salmon with a finger. If you feel the fish meat separating it's done. Depending on the filet size it should take from 15-30 minutes.
