Jake,
I agree with the above comment that it depends on your use conditions. I have two pairs on board:
1. A pair of 7X50 Steiner's that are my primary workhorse. They're in a box on my helm station. I use this for quick visual id's (e.g., checking to see if the boat that's bearing-down on me is DFG, USCG, pirates, etc.)..
2. A pair of Nikon Stabileyes (i.e., image stabilized). I use these for long range stuff like looking for birds, jumpers, etc. on the tuna grounds. These were very pricey binoculars, but, IMHO, they are some of the best your money can buy.
