I see that I am not alone. I would greatly apreciate any information about Seagoing Houseboats also. What interstes me particularly is how does an older fibreglass boad hold together? I have found a 40 foot by 11 five and it needs complete refit. I would like to hear anything but my primary interest if I do this is to have a boat that will run very cost efficiently. Any ideas on how I can do this with all the things that are required to have a decent comfort zone. Engines, gensets, refrigeration, heat and airconditioning it all has to be there. In return I will share anything I find out!! thanks
