That is one beautiful boat, Halekai.
By the way, I would be very interested in your experience with the CS 36. I am really just beginning my quest to go cruising, and am not ready, time or exeperience-wise to purchase, but there just happens to be a 1984 CS 36 available in my town. I'd like to at least look at her, and would be very interested in what you think I should look for. They have cored decks, don't they? Here is a link to the boat:
The CS line of boats are very well built and many CS-36's have done extensive cruising. My boat cruised for four years straight from Newfoundland and Labrador to the Caribe and beyond. They are very, very well built boats that also sail very nicely with a decent turn of speed. They don't get to squirly downwind and also track straight and balance well.
As for decks they are balsa cored but many of the areas of the deck like the genoa track and the toe rail/stanchions are solid glass! My deck has a few areas of dry delamination from it's time in the hot climes. These are not huge issues but I do plan on having it fixed. If it were wet delamination it would be a different story.
All in all these boats are built like tanks and have the weight to back that up. One very nice thing is that the stringers are solid glass laminated beams with no wood to rot out. There are also longitudinal foam core stringers running from bow to stern to additionally stiffen the hull sides.
Comparing displacement numbers tells a lot. For instance a Sabre 36 from the same vintage displaces 13,500 lbs (and these are considered very well built boats), a Tartan 37 displaces 15,000 lbs (another well built boat but a foot longer), and a Catalina 36 or a Hunter 36 also displaces 13,500 lbs and all of these boats have solid glass hulls & similar rigs and engines to the CS. The CS 36 displaces 16,000 lbs so the real difference is the heft of the hull. Mine is almost 7/8 of an inch thick up near the head see photo. I'd have no issues cruising a CS36 at all...
