Hi Florida;
I used to have an Achilles 14 with a Honda 40; Trailer was a 2-bunk, boat sat on the bunks just about where the floor and tubes met. A half-bunk supported the front half or so of the keel.
I used a transom saver similar to
this one, as when traveling, I noticed the transom would flex fore and aft as the motor bounced. By triangulating some of the weight behind the transom to the trailer frame, the fore-aft movement of the transom was largely eliminated. My motor was tiller-steered, so I also had to come up with a way of blocking the steering in a straight-ahead config (I used a rope loop around the trim tab, as I recall, that tied to the eye bolts on either side of the transom.)
Hope this helps;
jky
