I previously obtained specifications from the internet on our 1977 29.5 Buccaneer sailboat. It says that the beam is 12''3". We are trying to get a new slip, and the boat cannot be any wider than 12''. We went down and measured and came up with nowhere near that. It was closer to 11''. I would like to research this boat further. Any suggestions? We know that the boat hull was designed by Doug Peterson.
