Thanks for all the responses. How long you can "rest" an edge is what I was particularly going for. I was thinking of stropping and oiling a few razors and using each one once, but it does seem like a good idea to make some sort of travel strop.

While it depends on what type of boat you're on and where, for the most part I am on tugs that are in and out of rivers and coastwise applications. The interior of the cabin are, for the most part, pretty dang nice. I've been on tugs that were nicer than my apartment. New boats usually have all the amenities - internet, flat screen tvs, independent air circulation and really good food. I eat better out on the water than at home! It's all part of the deal since they want you to keep coming back. No matter how you slice it up, being gone 6 months out of the year kinda sucks. Hopefully I'll be going back to my old company out of Philly, but I'm also looking at New York and an assist company out of Louisiana.
