I thought it worked better than hard a/f. Here we a/f every 1-2 years,so it`s more likely to go the distance. Not sure it`s worth putting it on struts etc which don`t turn to spin the new little "barnies" off.What do you folks think.
Worth it on your running gear, versus regular bottom paint?
I did a test two years ago. Each propshaft, Propellor and rudder got different combos, to include cold galvinizing paint, Ala rustoleum, and abltive and non-ablative paint. No PS. Winner was painting interlux 2000 on bare metal and then two coats of non-ablative. The prop shaft with that combo looked new. Painted on in chesapeake and went to Bahamas on ICW and back. Cold galvanizing did not present much of a barrier.

I just had my Selene done and I found a noticeable reduction in my RPM to actual speed. Close to a 200 RPM reduction.
This may have been a bit confusing. Did you mean you were able to run 200 RPM less to achieve same speed as before? Or that you lost 200 RPM off your WOT? 200 less RPM to achieve same speed is good if all other conditions (weather and tide) were the same.
I did considerable testing years ago with Prop Speed & Came to this conclusion: I'd pick up .5-1.0 knot after a thorough bottom clean and paint. Then added prop Speed...no change in speed.. I find after new bottom paint and prop speed I will also pick up a .5 to 1.0 knot at wot to 19.5 - 20.0 knots..
The screw turns at 2,600. Just what the spec is. Considering currents, wind, tides, etc., I quickly recognized we had 8 knots vs. 7.5 knots as what could be a measurable improvement. The <7% improvement is strictly a seat of the pants calculation. It also takes into account 40 years of offshore and near coast cruising. To be really clear, “I was surprised “. [emoji41]

Nothing works better than Propspeed. The only downside (in this professional hull cleaner's opinion) is that it tends not to last as long as your anti fouling paint.
