They are totally different boats in design concept- I worked on the development of the Holland boats while working at the factory and ran the factory race program on the 36H and 33H-so I know them all to well-They are awesome boats-especially the 36. It was designed to the IOR rule at the time and rated in the 27.3-27.8 range-and were competitive. They are still amoung the fastest PHRF boats for their rating around. For cruising, the very strong TAFG(Tri-Axial Force Grid) and ocean-going interior make them very strong and GREAT sea boats, as well!
The 36C was an interesting attempt to build a tradional-looking boat above decks blended with a comtemporary hull shape. The result was a boat that sailed EXTREMELY well for a pure cruiser. The interior was innovative, but although I may be biased, I would probably choose the racier Holland boat even for purely cruising-this is for 2 reasons: I feel the newer structure (TAFG), which is also found on the King boats of the same vintage, offers a lot of peace of mind structurally, and the performance in my mind equates to seaworthiness. Not to say the 36C is slow-it is not, but this is my choice. If you like a traditional looking boat, then the 36C is one of the best choices out there.
Most of the traditional looking boats are full keeled, slow, and not close winded. I never undersood why so many people think this is seaworthy. If you can't get off a lee shore in a gale under sail, how is it a safe, seaworthy boat?
Happy hunting!
