You should buy the '78. The only reason i can give is that I am looking at the
'77. I also am doing this to livaboard. I am relocating from Oregon but will not be able to purchase until the end of the month. I will be depending greatly on the survey of whatever boat i decide to make an offer on. Was down last week and looked at many boats. Did you look at the Laguna 30 in the same area? Great use of interior space.
