Looking at the hull I have a few spots that the paint is off down to the fiberglass. Does this indicate a problem? What do I need to do in the spring to prevent this from happening again. I use an abaltive paint on the hull. Used in Lake Erie only.

Bottom paint

Don't worry about it. It's normal. When mine dose it, I just sand those spots a little bit and repaint them. When you haul out, be careful not to power wash your painted bottom to much. The pressure from the powerwasher will peel off paint that wouldn't normally come off from everyday use.
Beware of overzealous marina hands.
When I hauled my boat last year, the bottom paint was pretty much all there. I turned my back for a minute while the marina guy was powerwashing the boat in the sling. Next thing I knew, there were bare spots all over that he had stripped off with the power washer he was using. He took off about $100 bucks worth of paint in 10 minutes.

With ablative paints, the paint tends to wear away faster where there is higher water flow. At the bow for example. When you repaint, add an extra coat in those areas.
You could also touch up the bare spots in the same color yuo have now, then add 2 coats of a different color. If you see the original color showing through its time to repaint those areas.

Is it wearing smoothly or flaking? Flaking is a problem, just wearing smoothly near areas of higher water flow is normal and just needs to be repainted.
If the paint is flaking for any reason you might have applied one paint over another it is incompatible with or without proper surface preparation.

When you say you have a few spots that the paint is off down to the fiberglass I think about an application problem more than a wear pattern from water flow. Water flow takes the paint off slowly and it gets thinner and thinner exposing the color underneath. Your bare spots may be lack of adhesion.This can be caused by not preparing the surface properly. I use micron csc and got nine years out of my last bottom paint job with very little maintence year to year. I also boat in Lake Erie cruising and fishing. The best directions are on the can plus tech help is just a phone call away. Good Luck JIM

Sand the area down to get rid of the shiny gelcote, I would go larger that the flaking off area to make sure you get it all. Then wipe with a good solvent (Interlux's Fiberglass Solvent Wash 202 for example), change rags, wipe down again.
After that, paint, ablative will require 2-3 coats.
