This follows the discussion on Doug's u/sonic a/foul thread. We've gone off on a bit of a Propspeed tangent and I said I'd post some pics, but so as not to hijack the u/sonic debate I'm putting on a separate thread.
Pic 1 - this is the Propspeed applied, in Antibes by the local (very good) shipyard, September 2006. I wasn't there and did this by phone and they only put the propspeed on the shafts and props, not the P brackets and tabs. Ignore the scruffy a/foul paint - the boat was being lifted for an emergency repair so I didn't have the paint done, only the propspeed. The boat was re-launched 12/9/06

Pics2. This is the next liftout 6.5mths later. 28 April 2007, 6.5mths and 425nm elapsed since the previous lift. Those miles consisted of a big cruise in late Sept 06 then a few weekends out over the winter, and mostly the boat was idle sitting on berth. Incidentally, ignore the condition of the black a/f paint. I hadn't discovered soft micron 66 at this point so it's pretty scuzzy. It was on this liftout that micron 66 was applied for first time. The props and shafts are pretty good so the Propspeed did an ok job. Propspeed was NOT re-applied in this liftout

Next, pics 3, liftout was 14.4.08, 11.5mths elapsed and 1050nm since the previous lift. Miles were mostly summer 2007 and the boat was pretty idle winter 2007/8. Props quite a lot worse without the Propspeed (but the hull is just amazing - check out those pics, that's nearly a year in the med and the last few months sat on a berth going nowhere in winter, and the paint looks brand new. I'm TOTALLY convinced by soft micron66 paint.). In this lift, micron 66 was reapplied but no Propspeed was applied

Finally, pic 4, and it doesn't add much to the story, this is next liftout 24.2.09. 10mths elapsed and 590nm since the previous lift. Lousy props again but fantastic hull again (micron 66 again).

These are reasonable comparisons because it's the same boat parked on the same berth throughout
Conclusions? Micron 66 is fantastic on the hull. As for the props, actually, now I look at this again, the Propspeed is quite good isn't it. Can't really work out why I've not been more enthusiastic about it. It cost €520 ex vat, in 2006, and the bill says they applied 2 coats. That's 1/3rd the cost of ultrasonic (£1745 inc VAT for Ultra20) but it might have cost more (double?) if they'd done the rudders, P brackets and tabs, and I'd hope the ultrasonic will cure those. So if the ultrasonic works perhaps it's fair to say it pays back in 2 years compared with Propspeed. But at this point I've no idea if it's better or worse than Propspeed. Hmmmm....
