I'm on the press release mailing list for PropSpeed, hence knowing that Nautor Swan are now using the product as standard. I'm also interested as it would be useful if the fouling rate of props was similar to that of the hull as then you could treat both hull and prop at the same time.
I was achieving 2 years on the hulls of Josepheline with a top of the range 'commercial' (both expensive and difficult to source as a private user, Hempel's Globic and Jotun's Sea Quantum Ultra, both excellent ) AF but had to beach and clean down the props gently a bit over 12 months (which works for a multihull, and a bilge Keeler) but not for most yachts where you would need to expensively slip).
I've received another mail shot on Prop Speed, good PR consultancy (what's needed for Velux) that Prop Speed has been available for 25 years (I thought it was longer).
I looked at the ingredients about 10 years ago for both Prop Speed and the less common (poor marketing) Prop Gold aka Prop One and one of the 2 silicone based prop AFs listed an ingredient 'potentially carcinogenic' - but I don't recall which. This was some years ago and a replacement may have been found or it may have been proved, (seems unlikely) that it was not carcinogenic. Just be warned and take care - but this is true of any AF.
I have this vague recollection that Chiara's Slave used a silicone AF with out sufficient success.
