Thanks. I found the published data to be lacking. I worked with the dealer mechanics as well as a boat lift mechanic and we determined that 40” (out to out) at the stern and 32” at the bow with 8” deep bunks was the best setting. Keel sets about 2” above structural cross bars and is very stable. If you don’t pinch in at the bow, you risk hitting the keel at the bow or bearing on the hull chines when you raise the lift.
