If you are launching on a beach ramp or landing on a beach you may get pebbles stuck in under the centerboard (orbetween the centerboard and its slot.) I haven't tried pushing from the top but on occasion I could crawl under the trailer, see the pebble, and push it out. The centerboard rope also gets stuck sometimes if it is allowed to stay loose (hard to describe but it does.)
