in which case, depending on class of working boat, additional headroom is good (i'm 6' 3"!) BW license discount, owning a part of history, and in one form or another, allowing it to continue and adding to it, i personally would jump at the chance, they tend to be harder work to steer than modern boats, but in my eyes the pros outweigh the cons, but like any boat, get a survey, the footings go and the bends on the knees, but all can be rectified, if not already done (depending on fit out of course). Expect some dents on the hull, or as i like to call it, character!!
