We go out as B-split as a wrestler. you'll sail first tri of your 3/C year, as well as 3rd tri 3/C year and 1st tri 2/C year. You'll miss preseason practice for both of those years, but Coach is fairly understanding about that. He helps get us on a workout program before we leave and tries to help us figure out a way to be ready for practice when we come back. Most of the guys haven't had trouble getting back into shape once we get back from sea. It was rough for me and a few of the other guys this year for the first week, but after that we were all pretty good. You won't have to worry about missing much of sea year as a wrestler either unless you make it to nationals 3/C year. At that point you'd hold over for two weeks, maybe 3 weeks tops so you can compete at nationals then you'll head out to sea.
Hope that helps. I'm about to head back out to sea in the coming week actually.
