Some help please. My recently bought River Cruiser has a rather unwelcome sag aft of the keel and another pronounced dip round the rudder shaft. I advised that this is probably due to incorrect winter storage ie inadequate support; I also hav a suspicion that the replacement rudder about 20+ years ago is also much heavier than the original and has cotributed to the sagging around the shaft.
Question 1: is this possible to rectify by slowly increasing the degree of support a) in the medium term, b) over successive years c) not at all?
Question 2: Is there any chance of an insitu steamed solution? i.e. make up a steam box the encapsulates the hog (both inside and out and pump steam through for a few hours whilst VERY slowing increasing the lifting pressure from underneath).
The boat is extremely lightly made. She was designed that way, and derives much of her support from the water - more so than many other boats (she is 30' long). She is oak on oak; the hog is over a hundred years old and appears to be less than 2" thick by 6.75", the planking is about 30 years old.
