I want to mention a good zoom camera as a supplement to binoculars, such as my Panasonic ZS 200 with 1" sensor and 360mm equiv zoom. It is better than any binocular I've used on a moving boat for resolving distant details, such as a distant boat's name or buoy number. I take a photo at max zoom and review it on the back screen without concern for boat movement. The camera's image stabilization is important of course, but it's mainly about freezing the image and then staring at it for a few seconds, as opposed to attempting to fix in one's mind a constantly moving (and possibly receding) image.
There are far better cameras for this, such as the Sony RX10 Mk3-4 or an even bigger DSLR, but the Pany does the job and is tiny.
So would there be much difference in 8x40 or 7X50 glasses?
Anyone use a floating strap?
I mostly use my binoculars from inside the pilothouse, so I am not sure that I need a PFD for the glasses

The Fujinon 7x50s are light, float, have a compass, and are not that expensive, <$200.
For low light, the exit pupil matters. If you hold the glass up, the exit pupil is that that white round circle you see in the eye piece. In general the ideal exit pupil should be about a big as the human pupil is, for max light gathering. That's about an average of 7mm. The exit pupil happens to be equal to the objective (big lens) size divided by the power. A 7x50 glass has a 50mm objective and is 7 power, so exit pupil just over 50mm/7 = about 7mm.
The Fujion is a good glass for the price. I think the Steiner is worth the extra (more than double) price for the sharpness and durability. Mine are about 40 years old and like new. There are pricier and "better" glasses than the Steiner, but they don't match my investment/benefit calculus. Everyone has their own place.
I dug out my old WWII naval glasses. They were at the office. They weigh close to 5 pounds. They were made by National Instrument Co. from Houston. 7x50. They are fixed focus. Why are USN glasses fixed focus?

So Jeff, did Santa bring you binoculars? What kind?

Some things are too important to be left to chance. I’ve bought some of my favorite gifts.
THis Xmas, I was very glad to receive a Lie-Nielsen block plane.
I've had a pair of Nikon 8 x 23 for many years, barely adequate. Thanks to this thread I put the Steiner 7 x 50s in the cart to see if Santa would take the hint. She did! I tried them out on Tomales Bay last week and spent much of the time watching crisp images of birds not visible to my naked eye. What an improvement! Thanks for starting this.

Since we are not talking price, I'd say go for one with vision stabilization. Especially useful on a small 24 foot boat. Probably about 5 times more expensive that the standard model. But what good are they if you cant see anything because of all the bouncing around
I have decided to buy a pair of 7x50 Nikon binoculars
What's not on a boat costs nothing, weighs nothing, and can't break
OK, to bring this back full circle.... For my birthday I received a pair of Vortex Diamondback 8x28 binocs. These were my preferred pair after reading all the responses and talking to a few friends. These are very lightweight and have really clear optics. A big plus is that they have an easy adjustment that allows one to use them while wearing glasses or not. And, double bonus, the feature seems to work well!
I've yet to use them while out on my boat but I think they will perform well.
Thanks to all for taking interest in this topic.

I hope they are what you wanted
I just ordered a pair of 7x50 Nikon binoculars. I am hoping they're a real upgrade from the ones I am using.

I went with Vortex for both my binos and spotting scope. They are light and very user friendly and the optics are great. They also have excellent service -- no charge to fix anything that goes wrong.
The only downside -- both the binos and the scope had to go back to the shop for work. Remarkably, the binos had a human hair stuck inside one eyepiece. It was assembled that way! And a retainer ring of some sort inside the scope eyepiece worked loose so it wouldn't zoom properly. The entire eyepiece was replaced with an updated model. All of this at no cost. The turnaround for the repairs was quite speedy, too.

I got a chance to use my new Nikon binoculars out on the water. They are a huge improvement from the ones I had been using. Thanks to this thread for leading me to think about upgrading my binoculars

or.... it's the navy way or the highway.
I do suspect that naval personnel are not looking at anything close up. Hence the fixed focus.
You can adjust one eye piece to correct any deficiencies in your vision. These binoculars were my Dad's, adjusted to his eyes. My mother had her own set, adjusted for her. The two sets of binoculars sat side by side on the window sill in their waterfront house

For a bit of historical perspective...
Years ago, I paid $150 in a pawn shop for a cased 16 power USN Quartermaster's Spyglass. That was a chunk of change for my budget back then, but I couldn't resist it. It's one of those things I don't use often, but I'm happy to own it. It's rather unwieldy on a small boat at around three feet long, but you can sure "reach out and touch someone" with it and the "Arrrrgh" value is off the charts. They come up on eBay now and again. Like with any old glass, you have to make sure the lenses haven't clouded up. This Navy glass is adjustable focusing. Once you have your binoculars, one might want to snag one of these just for fun if you get the chance.

SCORE! That's really cool, Bob!
I bought Barska Floatmaster binoculars after reading reviews from this site. I am really happy with the purchase, you can see other best options as well.
Ditto the recommendation for Vortex. Basically a Swarovski knockoff at half the price. We have two big ones for home and boat, an a smaller pair for the bicycle. Rugged and well guaranteed.
About a month ago I bought an Opticron monocular for kayaking. I had been taking binocs paddling, but even the small Steiners were awkward at times. The monocular fits inside a life jacket pocket. Great for birds as well as identifying nav aids, distant traffic and so on. It's an 8x32 scope, less than half the size and weight of my 8x42 Vortex binos, and almost as good. The optics are very good for the price.

Forty years ago in Hong Kong I spent a fortune on a pair of West German Zeiss 7x50s. I’ve still got them; they have been overhauled once.
I also have a pair of East German Zeiss 7x50s for garden bird watching and a 6x30 monocular from the same people, which goes in a pocket.
The monocular on a Plath sextant is one of these. When I found myself putting the sextant telescope in my oilskins pocket I bought another…

IMAGINES VEL NON FUERINT
From 60 years of messing in boats a couple of things are worth mentioning.
7x50's are an optimum size because the pupil in your eye can't open much over 7mm. (To find an optimum pair you would divide the objective lens by the magnification i.e. 50 divided by 7 equals 7 (an optimum exit pupil) 35x6 is also a common binocular which (exit pupil 6mm) is pretty good and handy. On a boat less than 75 ft. anything with an exit pupil or magnification over "7" is not optimum. Note the greater the magnification the more difficult it is to hold them stable.
On my wee yawl I have two pair, the std 7x50 and a small pair 4x20 that fits in my pocket. When I am navigating in a channel, buoy to buoy in a small boat the movement is so great I can not read the numbers until I am on top of it. I then use the 7x50's to find the "mark" and the 4x20's to read the number...
On a larger boat this is not the case a much mare stable platform (most of the time) 7x50's are what I kept in the wheelhouse, and they are especially good for night vision.
My favorite for messing around in small boats are 4x20 Pentax which fit in my (buttoned) shirt pocket...
sometimes less is more, this is my experience
Interesting thread.
In 12 years+ of small boat sailing, sometimes in remote (often at least semi-remote) waters, I've never once had the thought that "Gee, I wish I had a set of binoculars right now." It's just never seemed necessary. Or even desirable. And most of all, probably impractical in a small boat with lively motion anyway.
I suppose my experience is shaped partly by the ease of eyeball navigation in the non-tidal waters I'm usually (but not always) sailing in.
But good to remember that the cheapest, and sometimes most practical option of all when it comes to a piece of gear, is to do without it.
(Do you think this is why some of my editors have stopped assigning me gear review articles?)
