My Morgan 35 (Hull Number 116) was modified exactly the same way. Roller furling boom and the traveller in front of the wheel directly beneath the boom tip. The boom is 13-feet 6 inches. I will check my boom to see how it is released and get back to you. (I think there is a release button on the boom). I do not utilize the roller reefing. I have a tall rig and even with the short boom, I often reef the main to ease the weather helm and heel of the boat. It balances very nicely reefed this way in winds over 15 knots. I sail it mostly around Long Beach, CA.
