Look, I'm not saying the mormon church is right, but if not for that church, I wouldn't be a christian today. I found christ because of a missionary from that church. I know that many of their beliefs are wrong, any gateway to christ is a good gateway.
Other than that, 2 things to remember when you hit the fleet.
1. Listen to chiefs, they may be enlisted, but the have more experience than any O-3 or below.
2. There is no mail bouy watch, no batteries for sound powerd phones, and if you need 50 feet of gig line, muster your division.:-)
