[Sentoa] Pac NW Bottom Paint: 1 Coat or 2

[Bevins2kellie at aol.com]

In Anacortes I use Interlux Micron CSC, 2 coats with an extra coat around  
the "skum" line.  
I paint all the metal with Pettit Zinc Coat Barnacle Barrier.
I can get four and if I really need it up to five years before  hauling.  I 
typically haul every three years.  The bottom cleans up  well with a pressure 
wash.
I am a diver so once a year I dive the boat to replace the zincs and  
clean/inspect the hull.
If the boat sits for a long time I get some growth but it is removed after  
running awhile.

Up here in Oak Harbor, WA. I have a diver clean  the bottom every three 
months, otherwise the rapid growth plus all the mussels  attaching themselves to 
the prop and rudder will slow me down significantly.  Just before the last 
cleaning, I was only able to get the engine up to 2700  rpm's. The day after 
cleaning, 3300 rpm's. The load was the same. The divers  always tell me the bottom 
painted areas will clean up easily with a soft  brush, but the mussels are 
really tough. The mussels never seem to attach  themselves to the painted areas, 
so the paint helps a lot from that  standpoint. I repaint every 3 years. I last 
used Micron paint, but I cannot  remember which type.

We  are hauling our 37 next month for bottom paint.  We used Micron CSC  
Extra last time, but I was really unhappy with the slime growth within a  month or 
2 of being back in the water.   Typically our yard has  only used 1 coat of 
paint, with a second coat around the waterline.   Also, within 18 months, the 
growth was substantial and I’m sure I was  dragging pretty hard as my WOT speed 
was down 2 knots. 
The  question is, what are other PNW tugs using for bottom paint, how many 
coats,  and how often are you hauling. 
Thanks,
