    I have had this concept in mind for many years.
    Boat1.jpg
    The hull form is that of a large sailing dinghy, wide for her length with shallow to moderate deadrise and a double chine. She would be 24’ long and her total beam would be such that she could be towed on the highway with a permit, but not requiring a pilot car. She would be powered by a diesel engine large enough to drive her to hull speed at half throttle. She would have a plumb stem and transom and a divided chinese lug rig with unstayed masts stepped in the bow and stern. The main mast would be only slightly longer than the hull, so it could be used as a ridge pole for a full size fitted tarp when the boat was used as a tent trailer.

    The keel would be a steel weldment and the hull would be either Bruynzeel plywood or steel. There would be a set of road wheels on a suspension system, which would be bolted to the keel, and a drawbar would be bolted to the forefoot. The cabin would be full width with tumblehome and low enough so that it would be easy to travel across it from after deck to foredeck. There would be sitting headroom in the cabin, but there would be a large hatch over the galley. (This would not be a foul-weather boat.) There should be enough room to store the road wheel assemblies if they were cleverly designed, perhaps in the aft coamings.

    The after deck would have a self-draining footwell and coamings swooping back from the after roof to terminate in strong carved wooden fairleads close to the transom. This feature would occur forward of the cabin trunk as well.

    The generous gunwale guards (2”x4” at least) would continue forward to support an anchor handling platform at the bow, and aft beyond the stern to form a bumpkin to anchor the mizzen sheet. If plywood were chosen for the hull, the chines would have external guards as well.

    Would anybody here be interested in helping to develop this concept?

    Welcome to the Forum WWP.
    Your concept design reminds me of some of the Selway Fisher designs by Paul Fisher. Have a perusal of his catalogue, and see what you think.

    In particular, I think that the Beaumaris 24 might be close to your proposal -

    Or the 25' Breton lugger -
    Yachts 24' to 35' https://www.selway-fisher.com/Yachts2435.htm#BRETON

    Note that they both have transom hung rudders, rather than an inboard rudder like your proposal. A transom hung rudder should be much easier to design and build (and to look after, re unshipping it when required).

    You have here a well developed plan for a sail boat, and a wild-*** development project for a trailering plan. Would you consider it helping if I explain how this trailering is a bad idea? What do you think will be gained from this development? Do you know what it takes to make this trailer street legal?

    I would give the following advice:
    1) There is no need to make the bow pointy. A transom bow above the first chine will save several hundred hours of work, improve interior arrangements, and not make a whit of difference to performance.
    2) Ditch the flange on the bottom of the keel. More than half the drag in this vessel will be in that flange. Double the web thickness if you need the weight, but a flanged edge is ...."not optimal". (There, I was nice...)
