That's nowhere near as interesting as your interpretation of what I wrote. From my post #9: Just about every fin stabilizers I tried were very comparably effective, when properly sized and commissioned: Naiad, ABT, CMC, Wesmar, Sleipner (also before their "Vector" stuff). From my post #14: I've been on boats equipped with ABT and CMC zero speed (straight) fins, whose performance at anchor was totally comparable with curved fins. Now, is my English really so bad to not understand that in the second sentence I only mentioned two other brands because they are the ones which I considered on par with Sleipner's curved fins? That said, I already mentioned that when it comes to personal experience, mine is as good or bad as anyone else's. So, if yours is difference than mine, fair enough, who am I to argue? What I find annoying is how frequently in these debates folks seem more interested to shoot the messenger rather than actually debating the subject. Is that a Southern Florida thing, I wonder? PS: ref. the tests that Sleipner ran on a Princess (56, as I recall), they were indeed published on their website, already back in 2013. But promptly removed not long afterwards - why, that's anyone's guess. Regardless, I was talking of proper independent tests, which shine for their total absence, up to current days.
