Look fellow Alberg Sailors.

The trick to remove any stuck bolt or fastener is to break the 
oxidation between the two different materials.
You can soak the bolt with Penetrating oil,Kerosene or WD-40 for a 
reasonable  time. Then try to move the bolt with proper socket wrench 
back and forth very little and again soak for a few hours...then do 
the same thing once again. In a few hours...before the sun goes 
down... that bolt will let go its corroded grip.
Where condition permit you can use torch heat and Penetrating oils 
(When part is cool).
You can use bolt Extractors (w/left hand threads or Square pegs) 
still with Penetrating oil. Drill a hole into the fastener for the 
Extractor or to pour oil inside the bolt.
Never try to remove a bolt or fastener by brute force.
Never Bugger up the bolt or screw hex-head or the screwdriver slot.
Never buy Phillips or Slotted screws...always try to buy Robertson or 
Socket Head Cap screws or socket Flat head screws.
Always keep you Screw drivers clean and Square....Do not use Screw 
drivers as Chisels.
