First of all, thanks to AlohaDan and others who have posted so much useful info.
Thanks. Have been laid up and haven't checked in here for awhile.
I am an experienced yak angler and am always trying out new things. I have had an AI for nearly 3 years now and usually troll under pedal power. I have been playing with deeper running rigs, everything from deep diving lures to trolling weights and flashers. I have rigged up some planers but have not used them yet.
Here are my assorted questions:
1. What are you using successfully to troll depths of 50 or more feet?
I use a deep diver sometimes, but not under sail. Under sail I have tried diving plugs like Rappela, but not too much success compared to a weighted bait running 5-10 feet deep.
If your going deep under sail, slow down. If you don't want to pedal furl in and jug along at 2-3 knots max.
2. The deeper rigs tend to put a lot of pressure on my forward mounted Ram tubes, often pulling them horizontal and to the rear. I have switched to the built in rod holders for deeper rigs but am also concerned about the pressuer on the rormold. Any ideas to help?
One of the reasons I quit using RAM tubes was because of this collapse under pelagic hits. So far haven't had a problem using molded in holders aft except for:
A. Two line configurations.
B. Mainsheet knocking rods overboard ( use heavy duty safety straps)
See my thread on building a rod holder so you can troll 2 lines

3. Are you using release clips or just a single line to include weights, lures, skirts, etc.
I use a single line most of the time., even with a small bird. Still experimenting using a "green stick" approach employing the mast . I have fidled with using a release clip when pedalling, not sailing, to give the lure more jerky action.

4. Are you trolling multiple lines while under sail? Differing depths? Differing lengths behind??
Two lines when bait fish (aku) are around. Guys here will run the short one deeper. Sometimes only 50-60 feet back. For bait fish I'm 200 or so back to avoid spooking them. Plastic pink nehu (anchovie).
Turn toward the longer line if possible when changing course. Or what I will do sometimes is turn 10-15 degrees only, pedal like hell for a count of 60, go another 15 degrees, etc.
If the wind is strong enough to run a bird, I run it long with a lure. Then drop second line with a bait fish (opelu=mackerel scad) on it back so it's about 10-15 in front of the bird.
I have had some interest from small marlin, but so far no hookups.
5. So far with trolling under sail, when I get a strike, I usually just turn up wind, control the fish, maybe furl or not depending on the fight. Also, depending on the fight I may or may not clear the other line. Does this sound consistent with your method?
Pretty much the same. The bigger the fish, the more the sail is furled, and for the really big ones I try to dismount it so I have a clear deck.
6. How do you determine the depths you achieve? I know there is probably a method for calculating but I don't know how to do it. Any help would be appreciated.
If you know the length of you line out (I'd mark the first 50, and 1st and sceond 100 with dental floss.) If your line enters the water at ~30 degrees your depth will be half the length of line out. More likely less than that.
Lot of these tactics depend on what your fishing for.
