Made my own. Cheap. Functional. Got 1 piece of alum tubing 3/4 in. dia. and one 1 in. both 5 ft long, insert small one so it slides inside the other. Drilled hole and put pin thru so whole rig is about 8 ft. tall. Put small window shade pulleys on eye bolts on top of 3/4 in.pole. Used old lead core plastic spools for the orange line (although if u can get em the use of old reels is a great idea) mounted to sides of cabin. Used an alum. flag pole holder for the base mounted to bow. Stiffened with 2, 3/4" alum. angle pieces with eye bolts large enough for the 1" pole to slide thru mounted on cabin roof edge. Mast base sits in flag holder and goes thru the 2 eye bolts about a foot above that. Whole thing breaks down easy.
