M_Boats: question for owners of Vanilla and Miss Q

I looked through the photos and saw that your boats are on Easy Loader trailers. ?I have one for my M 15 also. ?Have you had any stress cracks or other problems trailering without the keel being supported? ?I am wondering if I need to add keel support. ?I would rather not because I can remove the centerboard by jacking up the frame of the trailer. Thank you, Bert Felton M 15, Zephyr, #365
