PropSpeed
I had propspeed applied last haulout, for the first time. The boat is definitely faster, about a knot+.
Having seen the disgusting barnacle mess on props, shafts, skegs, etc treated with hard a/f, I was prepared to propspeed the lot, but the yard told me it only works on bits that turn, so doing the support brackets was pointless, and the stuff is expensive, so I didn`t.
Judging from Baker and Marin`s posts fouling here is much greater than the other side of the Pacific. If I get 18months out of good quality a/f (Jotun Seaguardian), I`m happy.
The advice with propspeed is operate the boat minimum monthly and the barnacles just spin off.
I heard about a DIY propspeed, mixing silicone sealant into some solvent and painting it on. I`m staying with propspeed, but I get the idea.
The surface for propspeed has to be totally clean. We`d just replaced one shaft and had the prop reconditioned so only one side needed prep. My yard was happy to apply it, but I`ve heard of other good yards, like Fenwicks, at Brooklyn, getting someone in to do it.
