Hi Thomas,
Some tailpieces have small "shim collars" inside the locking devices that are a bit hard to get out, but I'll bet you have run into the "need to sping the boom" to keep the tailpiece tubes aligned with the boom arm tubes.
Try to spring the rear of the boom arms apart a little as the boom arms are normally the more difficult to spring open as the ends of the tailpiece tubes are a bit wider (when not inserted in the boom arms)
apart than the boom arms.
So, try spreading them out so that the tailpiece tubes can slide out through the lock mechanisms.
What model Chinook boom do you have?
Hope this helps,

Hi Tom.
See the latest reply on this@:
Often there is a tiny "mis match or oval condition at the front of the locks.
There are plugs in the end of the tailpiece tubes, and these also may have little "step" or misalignment that causes the boom to "stick" just before the tailpieces come out of the boom arm tubes.
Often pulling them apart (the tailpieces are at an angle with the centerline of the boom so either the boom head has to flex open a bit or the rear end needs to pull together a bit to allow the tubes to align.
Hope this helps,

Another Option.

Gaastra makes some harness lines that just strap on, without having to take the tail piece off. I have adjustable outhauls on most of my sails, so switching out harness lines it a pain. I just cut off the old lines and attatch the new ones. Takes 5 minutes.
