Trailer information for 22' Spindrift

[Robert Mike Gilbreath]

I'm adjusting a boat trailer for my 22 spindrift. How long should bunkboards be and width between bunkboards? How high they should be? Just help me get in the right neighborhood.

You might get a pretty good idea of how long and wide the bunkboards and keel supports should be from the photo below of a Sprindrift 22 on its trailer.
