The center board was appx 100 lbs but as MaxinCalgary pointed out, it may be difficult which may require the winch. However, may I suggest you look up into the centerboard housing when the boat is out of the water on the trailer to make sure nothing is fouling it for example barnicales, debri, marine growth and so on. make sure the centerboard line is 7/16 not 1/2 and is not binding anywhere. Keep us posted.
