i just came up with a great idea for my mast and boom i have a fishing rod i dont use as the tip got broken.the two pieces i have are the correct size in diametre and i can cut them to length.i though about leaving the lined guides on and using them to attach the sails.hows that sound to you? they are carbon poles it cost a lot of money when i bought it so its very light and strong.nice colour too should work i reckon saves buying blanks all i need to do is attach the boom any ideas on this? maybe pop rivets etc?.i think one of those links has some info on this ill have a read up on it.
