Re: Salmon fishing with downriggers in Washington State
Hi Dave, Im not fishing expert but I do a lot of it anyway
1) The humming is the cable vibrating int he water. Nothing you can do about that as far as I know. The slower you go the less hum there is. Your ideal trolling speed will vary depending on what you're fishing for and what type of lures/bait your using. It can vary from under 1 mph to 3 or 4 mph or even higher in some cases.
2) No way to keep the ball from showing up unless you go so fast its behind the cone of the transducer. Personally, I like being able to see it. That way you know for sure what depth your fishing at and how that relates to the fish you mark on the screen, fish balls, thermocline layers,
THE BOTTOM, etc etc. If your fishing close to the bottom - which you must do in many cases - then knowing exactly how close you are is critical - unless you dont mind loosing expensive balls and gear. Also, depending on the size of your boat and where the rigger is mounted, a snag has the potential to sink you!!
Your downrigger depth counter will NOT be accurate due to blow back of the ball. I personally do everything I can to keep it on the screen.
3) Lots of folks use 2 cycle and 4 cycle kickers. Unless your willing to spend over a grand on a saltwater electric kicker, your stuck. Do NOT use one in the sound unless its saltwater rated. It will die in short order.
That said, sometimes in lakes and especially in shallow water I use my Minkota. However, unless you're prepared to install a couple of extra large deep cycle batteries, dont plan on trolling all day on the electric motor. They draw a significant amount of current and can drain a batter in just a couple of hours. A
Also on that same note - never use your electric kicker on your main starting battery - unless you like getting back to the dock on your kicker or by rowing
Most outboard charging systems are incapable of re-charging a deep cycle thats run down very far unless you run a LONG time. So dont make the mistake of trolling for an hour and then think that running the main outboard will re-charge the battery in a few minutes. It will likely take hours instead.
I learned that lesson the hard way. Trolled for a couple of hours, then made a 10 minute run at hi speed to a new spot and trolled for another hours or so and found out the outboard would not start because the battery was run down too far. oops!
For some good tips on downrigger use, how to set up flashers etc as well as places to fish in the sound, try this site:
Salmon University Fishing Education - Salmon Fishing Techniques, Reports, Lessons, Advice and Recipe's
Lots of info there to keep you busy for a while
Good luck!
