Decided to do a little market survey of my own... especially after reading Dave's comment about Canon vs. Fuji degrees of stabilization and effectiveness on boats...
Hmph.
Don't see a perfect answer, on paper.
Neither Fuji nor Canon are "always in focus" and I really hate yutzing around with a focus knob. (Spoiled by our Steiners, I guess.)
Fuji's 5° of stabilization vs. Canon's 1° (at best) makes Fuji a clear (on paper) winner on that criterion, but that's offset by having the shortest eye relief (Technostabi, 13mm) which usually sucks for eyeglass wearers.
Canon apparently does have some gyro-stabilized models using what they call a "lens shift" technology -- 14x32 IS, 12x32 IS, 10x32 IS -- and those may be a bit better for working from a boat compared to the 15x50 and 10x42 models. Better eye relief, but not great. Still only 1° of stabilization, though.
The Fujinon Technostabi is the heaviest, but I see only a few ounces heavier than my 7x50s with compass, so not horrible, at least for me. Might be a bit much for our primary user; have to see about that with in-person evaluation. Interpupillary range might also be an issue to be considered in-person.
Fuji's Technostabi are waterproof, good. No mention of waterproofing on the Canon "lens shift" models, so I assume they're not. Their 10x42 L models are waterproof (.8° stabilization), and the 15x50s (.7°) are called "all weather." Our bridge is fairly dry, though, so not a huge issue.
For us, I'd lean toward the Technostabi on stabilization and most of the various optical criteria -- except for the eye relief, and I'd have to judge in-person/hands-on whether that can work. I still wouldn't like (detest is the real word, and I seldom use that in normal conversation) the manual focus thing. And then our likely primary user would get the real vote, likely based on whether the weight is manageable and whether they'll adjust so the eyepiece separation is narrow enough.
Given the (at least) 5x pricing for Fujinon's Stabiscope models... and their weight... I'm not considering those as viable within our budget. <sigh>
