Bill Hendrix at mainsail Marine in Greenville SC has an inexpensive option involving a set of unique sandbags. Works better than anything Ive seen, and as long as the bags are kept clean, no scratches or dings will result. Light and portable and easy enough for one person to use.
BTW he has a highly modified TheMightyHobie18 that uses them with, and his wife's Trac 16 and his friend's Mystere 6.0 all sit on the same beach and use these.

The men were amazed, and said, "What kind of a man is this, that even the winds and the sea obey Him?" Matthew 8:27
