Thanks a lot MYlover, very interesting pic indeed. Confirms that you are measuring EGT downstream of the turbine, as I already guessed based on...
Well, they were/are also very good, both underway and at anchor. I'm not saying just as good as the vectors, because that would be a bold...
I'd be very interested to see that, if the search isn't too much of a hassle for you. Thanks in advance, regardless of whether you will actually...
When I said that I tried Sleipner stabs, I specified "also before" their vector stuff. By implication, I hope you'll agree that this means both...
The only MAN engine I can think of with a power rating of 820hp was the very last mechanical V10. After that, on the V10 block, they built the...
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...
If you are positive that she was repowered in 2000 and with 1300hp engines, they must be the so called D2842LE404. Pretty rare beasts, which were...
Haha, JWY surely has been, and I guess still is. But at the same time, she's realistic enough to know that perfect they were not - as well as any...
I couldn't agree more: that's precisely the type of test which I have yet to see not only between gyros vs. zero speed fins, but also curved vs....
Mmm.... Actually Magnums (as well as Itamas, just to name a similar style boat) are built upon rather beamy hulls, for any given length. The real...
Well, my experience is different. If properly sized, I would call gyros better than fins, at rest. Slightly better as I said, but better...
Rated WOT is indeed 23oo with both the 3408 and the 3406, and also with most MANs. CJ is right about MANs, though: 2000rpm and 80% is still...
I'm saying that because it's not even worth trying to stabilize a 40' (or also 50') boat capable of cruising at 30+kts. With such vessels,...
I would agree with the gyro vs. fins part, but the real reason why they stress also the supposed higher efficiency of curved fins is, quite...
Apologies if my memory is mixing up engines and their displays, but assuming we are indeed talking of the 3408s, I half recall that they didn't...
Considering the age of the 3408s, that might be somewhat related to lack of usage (like injector nozzles corroded, as an example), rather than the...
Thanks to you for appreciating! :) Btw, I forgot to mention that the above is also the main reason why gyros are very good at anchor (slightly...
There is no reason why forces should be higher on the external side of the fins, since the rotation angle is exactly the same in both directions....
I'm not sure if the subject was already debated in this forum. It certainly was - extensively! - in the European forum, on YBW website. And...
Sorry, I can't answer that. I crunched about 12 hundreds miles right after purchasing the boat, to bring her to my home berth, all at planing...
