We just purchased a new 2008 Hunter 146. After the initial rigging, I thought I would leave the main sail on the boom and cover it for storage but when I lower the mainsail the back of the boom drops into the cockpit fo the boat. Is this normal or is the boom supposed to stay up. I always thought that the boom would have a fixed position 90 degrees to the mast. I am also having difficulty rigging the furling jib. Please let me know if you have any advice or can share any diagrams. This is my first experience with a monohul sailboat.
