i have a 203 Hunter 306. yesterday i climbed the mast to place a new antenna. when i arrived i noticed there was no MPH to assist me on my climb. when i came down i saw that the furling mast had a pull line for a spinnaker. would anyone use this as an MPH location. there is plenty of room for a block at the foot of mast. i would need to install a cleat to tie off to. I saw a few plugs//holes in the mast. possibly use that site??? I do not plan on purchasing a spinnaker now or future. i have to go back up as the masthead light lens was cracked. does anyone know if you can buy just the lens. thank you tom
