draft of 1990's 37.1, 37.2

[geoff]

My recently acquired 1997 Sun Odyssey 37.2 appears to have a draft of ~ 6'6" (1,98m) or so when measured on the hard in a cradle based on the scum line observed at the end of the season. The keel is iron with a bulb. Jeanneau's specs on this site (and elsewhere) state a deep keel draft of 6'2" (1,87m) although Boat Sale sites vary this number a little.
Does anyone have any insight into this?
Many thanks
