I have 31' Carver that was bottom painted in 2008. The boat has been hauled for routine maintenance. The 2008 paint looks pretty good, after pressure washing. I am thinking of light sanding and recoating with one coat of bottom paint.

The boat yard naturally advises to sand down to the barrier coat and put two new coats on at $$$.

The boat is kept in freshwater in AZ.

Any thoughts. Thanks.
 
I think that you are correct. # 60 sandpaper, masking tape the edge, and put a new coat over the old. Use a household paint roller and throw everything away when done.

Is the current paint a hard paint or ablative? How many coats are on there now? You really need to answer these two questions before anyone can advise what to do next.
 
+1 what 32 Carv said, that is exactly what I am going to do. I got a gallon of Pettit Hydrocoat. It is waterbased. Pettit said just lightly sand to rough up the surface and apply. But MikeeH is correct, mine is albative so i am going over with another ablative. He gave me some good advice http://www.boatered.com/forum/topic.asp?TOPIC_ID=145061

I plan on doing only the water line and then as far as the gallon goes. I figure at least it will look good in the water.

Joey, are you at Lake Powell too? I am on the Utah side up at bullfrog.
 
What MikeeH is real good advice I purchased a 33 ft Well craft in the fall hauled it out in April to repaint the hull and found that there was 13 coats of paint applied. I finally have it back down to the Gelcoat, hopefully this coming weekend weather permitting I should have this done.
 
Pressuming you are going to use the same paint as the 2008 job, what you want to do is fine. No need to totaly sand off a bottom job from 2008 unless it's failing. Just sand with 80 grit to get the dirt off and roll on another coat of the same stuff. Compatibility shouldn't be a problem.
 
You can't paint a hard paint over an ablative. Well, actually, you can but you won't be happy with the results ;). On the flipside, you can paint ablative over a hard.

Paint = weight. Weight = fuel.
