Hi George,
Saw your post and I took some measurements while working on our W42 today. I am doing a pretty much complete re fit. :
Engine, shaft, propeller, all tangs, chain plates, standing and running rigging, mast, travelers, rudder, pedestal, bowsprit, port holes, adding numerous extra ports, interior cabin sides, cut out deck on foredeck / reinforce and install large hatch, electrical , complete fuel and water tank removal and removal of all stringers and bulkheads in that area, redesign layout to accommodate tanks that can go through companionway and glass in new stringers and bulkheads. In redesigning ours, I cut the furniture in areas that will allow the tanks to be removed w/o totally taking out all the furniture, hopefully the furniture and deck sole will be able to be installed and removable for possible future replacement / serviceability ( not in my life time ) . On and on :)
Here are the Measurements:
Height at companionway - 6' 3 1/2 "
Height at step-down leading to main salon / small area before cabin top steps down- 6' 9".
Height in salon area after cabin steps down - 6'.
Height in passageway leading to aft cabin - 5'.
Height in aft cabin / stateroom - 5' 11"
Height in engine room - 4' 10".
Oh, whatever vessel you look at, take a very close look at fuel and water tanks. If they have not been replaced, they will probably will have to be replaces in the near future. This is a huge project. On our W42, the main tanks were sitting on the bottom of the upper bilge which is NOT a good way to go !! There were 1 1/2 " hole in them when removed and inspected.
Hope this helps. Of course heights may / will differ with each individual vessel's layout.
If I can help in any way, let me know.
Best regards,
George
