What sort of rigger do you have?
I use a Cannon Easi Troll. I have this mounted on the gunnel like most I have seen. A mate has his on a rod holder bracket and it works fine but beware of the need for a very strong rod holder as there is a great deal of force involved.
In a glass boat the wire is fine as it does not hum. In a tinny its probably worth running something like Cabelas Depth Trac braid. I use this now as I have 400ft of cable (not needed in the Bay )
I regularly run two lines from mine. The first is clipped off on a Cannon release clip attached to the bomb and then I release 5-10m of line and clip on a Cannon Offshore Stacker Release and clip on the second line.

If using braid it can be more secure if you wrap an elastic band around the braid then into the clip as the braid can slip out quite easily and its a pain to reset the whole thing without a hit .
My bomb sits in a side pocket when not in use (still clipped on) but you may find a weight holder worth having.
It takes a few trips to sort out the best way to use it but when you do you will find its a great bit of kit
