When we run in our trawler like to try for dinner. If your on a ship Idon't think you will be stopping for a fish. I tie 100 yds of 400# mono, use a bungy cord as a shock cord,5' of 200# cable and a large Rapala. I have this all set up on a Appx. 10" plastic spool that I purchased for about $5.00 at a local tackel shop. I hand wind. It's not real sporty but it puts the vittels on the table. If you can't stop I think you would be hard pressed to reel it in. I only travel at about 10kts and if I don't slow down it's a tuff pull. I also let them fight the trawler for awhile.

I should also add, I have seen the local fuel tanker running around the Bahamas with what looks like 800#??? or more mono tied to the rail and they just toss it over the rail about 20' ahead of the stern. They hand line it and coil, & tie to rail when not in being fished.
