NT37 Fishing Setup update:
Been wandering around SE Alaska for the last several weeks. Installed Scotty electric downriggers, using their right-angle mount, which attaches to the inside of the cockpit and rests on gunwale top, somewhat similar to the pictures posted above. Easy to install, seems plenty sturdy enough. Easy to remove and get most of it out of the way when not in use. Top of gunwale on the 37 is about 4" wide.
Ran wiring for 12V power plug from the stern thruster battery in the lazarette. Using the mount and power source for a Scotty pot puller also - a marvelous little device which has brought us a couple hundred spot prawns so far. Yum! Crabbing and halibut fishing works just fine as well.
Wow is the electric downrigger nice compared to the manual I had on New Moon! Have not done a whole lot of trolling yet, but caught 10 coho in 2 hours on the outside of Yakobi Island, west of Elfin Cove, a couple of weeks ago. No trolling valve or kicker, just trolled at idle speed (3.5 knots), and sometimes took it out of gear on and off to go slower.
Biggest difficulty is cleaning the fish and cleaning up after - no salt water washdown in the cockpit yet. I am pretty much decided against the trolling valve. Still considering the kicker.
