Trolling soft baits is another way of effectively catching fish.
Slower vessels like kayaks and other small water craft are particularly suited to trolling soft baits.
Species that you should expect to catch can range from tuna to kingfish and kahawai, even marlin have fallen victim to soft baits.
The best type of soft bait to use when trolling soft baits are the ones with good tail actions like those mentioned in the deep water section.

If considering trolling, it is best to use a rig that allows the soft bait to swim along as naturally as possible which also prevents the soft bait from rolling as it is moving along.
My favorite type of rig for this is made up using the Jigstar swivel head and The Captains elevator hook.
The head allows you to attach your leader in one of two different positions which allows the user options for fishing style.
Attaching to the loop situated at the front of the head allows for better trolling, while the one found on top is better for working across the bottom.

It is important to use the correct head weight for trolling as this will have a direct influence on the way the bait is moved through the water as well as effecting how deep the soft bait will sit in the water column.
Again this can vary depending on the many factors the marine environment offers like current, troll speed, wind and tide.
