Mike If I kept my boat in the northwest Arm I would go with Bob's experience...use Micron 66 if you can get it...as you know Bob is quite meticulous about Azura and he follows manufacturer's directions well...one year he had so much growth on his prop (2 blade fixed) in late september that the boat had a hard time making headway under power...the prop was foulded extremley bad...next year Bob asked this list for advice with his prop fouling issue...I knew he had such good results with Micron 66 on Azura's bottom so I suggested that if he didn't mind having a painted black prop before launch rather than shiny bronze he could just try painting it as well with Micron 66...I believe he did paint the prop and achieved good results...something about the critters in the Northwest Arm, very prolific... and somewhat resitant to normal copper oxide toxins...Micron 66 might just have the right copper toxins and added biocide for the moment...but those critters adapt to their environment so this coming season may be different, anyway you have seen Azura with your own eyes, think you could expect more than that from any paint. Micon 66, Micron CSC, Amercoat ABC 4 or???...if you are looking for more speed, look somewhere esle for bigger gains, the performance of thse paints are quite similar...if your boat's bottom is in top notch shape go for one with multiyear ablative properties and do the job once ever 3-4 years instead of every year, like i do. The copper oxide content is primarily resposnbile for the higher cost of some antifouling paints and the better paints often weigh more per volume due to higher copper oxide content
Yes I use Amercoat ABC 4 and like Mike Amirault says my boat spends the summer on a mooring right at the head of the Bay, sort of brakish water, shallow at about 12 feet and warm enough for swimming from mid june until september...Amercoat works fine for me but I apply a thin coat (about 2 liters solvent diluted before spring launch every year) so one gallon does about 2 years...no pressure wash after haulout and very little prep before application before launch...I have used Micron CSC, expensive by comparison and no noticebale difference...I use a very thin layer of black Amercoat over blue Micron CSC and no issues with adherence...I have noted that Mike's C&C 33 MKII is very slippery as well Dwight Veinot C&C 35 MKII, *Alianna* Head of St. Margaret's Bay, NS d.ve...@bellaliant.net On Tue, Mar 10, 2015 at 11:19 AM, Hoyt, Mike via CnC-List < cnc-list@cnc-list.com> wrote: > Bob told me about Micron 66 repeatedly and showed me Azura bottom in > December.
