Seems like an obvious question, but couldn't find any significant discussion in past threads. Would it be worth buying some IS bins primarily for use on pelagic trips? My hope is that IS would make high mags, e.g. 15x or higher, practical on a boat, or at least provide a steadier image in average choppy conditions.
Found one comment suggesting Canon IS didn't work well on a boat, but there wasn't much detail on that, or comment as to whether other IS systems might work better.

There was a writeup some time ago which indicated that on the water the Fujinon 14x40 stabilized binocs were superior to the Canons, but there was no substantial explanation beyond some claims that the Fuji glass could stabilize a larger motion.
The Canon 10x42IS is fully waterproof and would be a good glass anywhere. However, the Fuji comes from a heritage of superb marine glasses, so even though it is even more awkward than the big Canon, it is probably the better choice for the very well heeled boater.
I've used Canon IS 10x30, 10x42L and 15x50 from a boat. Not in particularly rough seas, but in dull conditions with choppy waters or a significant swell. I'd say the ones that worked best for me were the 10x42L, possibly a combination of the IS and the superior optics.
