I also need to run some wires to the bow for a trolling motor on my 2001 13 Sport.

You can use flexible plastic "wiremold" or "Panduit" surface wiring conduit. It is available in a variety of sizes. I have an aftermarket set of speakers that TC Marine installed on my boat left and right about halfway up the forward gunwale. I had contemplated removing the port side speaker and using a flexible bit that electricians use to fish Romex wire in houses. I really want to hide the wiring if I can.
