Honestly,
I think the best thing is not to use the bags unless you are going to travel long distances.  What I do after each use, I rinse the boat, leave to dry and then put the hard top cover on top, leaving the foil and all in side the boat.  I'm not using the soft cover bags at all, unless and traveling long distances

I always try to let the boat dry before putting the hard top cover on it, but sometimes it still has some water drops around the hull, and so far, no problem at all.  I think you wont have that issue with the hull

Storage does not need a padded bag - if boat is stationary and things are wet leave out of bag. If trailing when wet take out and dry when you get home.  I usually leave mine loose not in the bags in the boat in the dinghy part but use the bags (only) when travelling to open meetings.

Hi This is problem is Osmosis. 
 
To cure the problem we can do 2 things:
1. Use heat and moving air to pull the moisture back out from under the gelcoat. In the workshop here we use a hot lamp and fan heater. The part will need to be left for several days for the bubbles to retreat. This will use a lot of KW. Or you could put in warm dry place such as an Airing Cupboard or boiler cupboard for a couple of weeks.
2. Pop the bubbles, dry the area out and  reapply gelcoat. Personally I lean towards the 1st option.
 
To prevent the problem from reappearing:
Only use the padded rudder bag for transportation purposes and make sure the blade and bag are dry before use.

It's moisture, not heat, that is causing this. Not only do you need to make sure the blades are dry before you put them in the bag but you need to make sure that the bag itself isn't wet. The RS supplied bags soak up and retain water like nothing I've ever had before. I noticed a couple of blisters on my blades a while back but they go once the blade is dried out. In the meantime, make sure you don't inadvertently 'burst' any of the blisters or you will end up with a filling job to do.

I bet that's what it is. It's my fionce's boat.  She hasn't sailed it for a while. I just asked her if she stored the boat, with the blades, in their cover, wet, and under the top cover (inside the boat) and she said yes! That boat stays outdoors, with the top polycotton cover on but no shade, so I bet it was from the heat like you guy said!  What should I used to recoat it?
Thanks a lot for the help guys

Are you storing it the daggerboard wet in the bag? it looks like humidity blisters.

Make sure the blades are dry before putting them in their bags.

I discovered recently, on one of our Aeros, weird bumps/bubbles on the coating of the daggerboard (see attached photos). Has anyone ever experienced something like this? Any suggestions on what to do?  Thanks
