    Tools are just tools not the tool maker. The tool maker must decide what tool to use for the task at hand.

    What is the right tool for evaluating dinghy relative performance? SA/Righting-Moment (which considers crew weight, crew position, and center of buoyancy at optimal heel angle)? We are far enough off topic, that we could be starting a new discussion thread. Maybe there are already several on this forum...

    Back to the original topic:
    1. No production sailboat ever met all these criteria: wood hull, centerboard, planes, 26LOA?
    2. A Raven is too short, as are almost all wood planing centerboarders?
    3. An E-Scow is too long, but otherwise meets the criteria. Buy one, chop off the stern and install hinges?

    griffinb,
    Forgive me for straying from your questions.
    It seems to me the Raven is pushing the limits of a wooden centerboard (trunk) sailboats. Your questions 1 and 2 above seem to suggest that?
    Sometimes if there aren't many of something that have been built to our desired specifications there must be some reasons.
    The boat designer and builder has the last word on the boat that they will build because they will bear the scares and the responsibilities.
    I hope you find the boat you are looking for and have many adventures.

    John, thanks for considering my challenging search. It's true that 26' is quite long for a centerboard sailboat. Righting after a capsize would be a handful. If I were designing with a clean sheet for these requirements I would prefer a swing keel (weighted centerboard, NOT a canting keel) for self-righting, and stability at mooring. BUT, I would not want it in a trunk. I would prefer the type seen here (what is this type called? With the majority of the centerboard offset downwards from the pivot axis, so that it does not retract into a centerboard trunk?)

    The race is handicapped by the Classic Rating Formula (CRF):
    About CRF - Classic Yacht Owners Association https://www.classicyachts.org/ratings/aboutcrf/
    I've already gone down that rabbit hole, and decided that if I ever build a boat for this race with a clean slate, it will be a gaff schooner. They have the biggest advantageous ratio between their rating penalty and their theoretical aerodynamic efficiency. A topic for another thread, if/when I design from scratch...

    I'm not sure the Atalanta 26 ever planed. The cockpit is deep and narrow, which indicates crew hiking won't contribute much to righting moment. Also, it is undercanvased:
    "The sail area of 240 sq ft is small for a 26 footer and can effect the boat in light weather (nothing a cruising chute or spinnaker can't sort) but they are extremely good in a blow and can stand up to a top force 5 with full rig up."

    Build a sharpie. Classic Chesapeake design going back to the 1800s. Very fast and highly competitive. No controversy about the origins from Herreshoff and Clapham right up to today.

    If I could find a used 26ft wood sharpie, I might be interested. I would check w the race organizers whether it would be considered a vintage design. If they don't accept it as vintage, then it wouldn't be allowed. Hard chines aren't allowed on the modern Spirit of Tradition boats.

    If I'm building a boat, I'll just start with a clean slate, and the amount of time that goes into building the hull is small compared to the total process, so I wouldn't necessarily go for simplicity in hull shape.
