I am wondering if there are any Coronado owners out there who might have some advice for me. I'm sure that some of you have experienced the same situation that I find myself in currently. I have owned my boat for a few years and have recently started a floating overhaul (not dry docked). I have gutted the interior including the 3/4" wooden ceiling. I assume that this wooden ceiling was at least partly structual. My plan is to replace the ceiling with 1" X 1" wooden ribs and fibergalss them right into the deck from underneath. Is this a good idea or should I consider other options? Thanks in advance for any suggestions or advice that you are able to offer.

Alex, If you do any cold weather boating

then condensation may be a problem that you have to deal with. Consider reinforcing the deck with Corecell or Airex and glassing over that. It will give you the added strength and will add substantial insulation.

Corecell or Airex...

is that a kind of kevlar or steel/fiberglass layer? I'm not familiar with either of those names. Thank you for the suggestion, I will Google it right now!

Did you get to this link?

http://www.atlcomposites.com/products/cores/end%20grain%20balsa/index.htm# They can tell you a lot about the world about structrual foam and composite structures. Check back for more discussion on the details. I have some experience with these systems. Edit to add: I just checked the link. Click on the ATL Composites in the "this page can't be found" page and you will get what you need.

Thanks - sounds like a very good suggestion...

I did find that site but I haven't found much in the way of instructions or tutorials. Is it fairly straight forward to apply? I am under the impression that it can be sprayed on like most other kinds of foam or it can be laid on in sheets - is that correct? I think sheets sounds easier if that's an option. I'm guessing it would be like applying a sheet of fiberglass only thicker. Sounds like something I could handle fairly easily. I appreciate your help with this!

Alex, the material comes in sheets

and is installed in an adhesive called corebond. There are books written on the details of the installation. The process is too involved to explain here.
