The sailing rudder does extend a couple of inches more than the standard rudder, so you can't stand the PA up on the rear without crunching the rudder.
For me, it's not a problem since I use the trailer.
The rudder is about 25% larger so basic tracking is better......hence "sailing rudder".
Instant improvement once sailing rudder installed.
Shortening the arm so the down rigger is closer to the hull is critical....If you can twist/adjust your arm to simulate the effect, you will see how much better tracking becomes.
Yes, I still use the same weight for deeper trolling.....I tried 6 pounds and the extra drag is a PITA.
The extra drag from a 5" quick fish lure, trolled about 70'-80' behind the down rigger just adds to more pedaling effort.
I typically cover 6 miles in 4 hours....sometimes up to 8 miles with a smaller lure.
Here is a nice, fat German Brown Trout and a large Rainbow/Steelhead Trout that a friend is holding(modeling
) for me. All taken at depths below 35'.
