My Sunrider 25 has always been subject = like most 20 - 80's boats- of deck compression when mast stepped. In fact my boat has a good indicator of when mast is tensioned OK - whether bog door opens easily.
Because of the SR25 tendency to carry weather helm, last 2 years I have stepped mast as far forward on the deck blade as possible. Mastfoot is the inverted U foot that then has bolt through a vertical blade on deck. That blade has 5 possible bolt positions ...
As part of my 'exercise' to start walking again after fracturing vertebrae ... I take short slow 'walks' in garden. Other day I decided to push the envelope and 'hobbled' down to my pontoon and boat. I could not climb on board of course but while resting to start the 'walk' back to house - I looked her over.
It was quite obvious that there was compression of the deck from the mast. Not a great amount ... but the eye is remarkably adept at seeing such.
Until I can actually move around fully it will have to stay as is. It looks like stepping so far fwd on the blade - may be pressing on the fwd edge of the doubling pad under deck and causing fwd edge to be pushed down. Hopefully later returning mast to a position aft may solve it.
To add extra support underdeck may not be so easy as a full transverse bulkhead 'beam' already is there.... with no signs of crack / breakage.
