Pipe should work and would really relieve stress to the hulls. Try this for the line. Feed furler line thru blck with becket and tie to bridle wire by fuler. Have the block be about 2" from the furler. With the jib unfurled and the jib sheets and block attached, just pull the 3/8" or so line and for every foot you pull it will furl 2. Real nice between race in moderate winds to keep it from flapping and when wind is to much. Be SURE to tie a figure 8 knot in the 3/8" line after feeding thru cleat so it won't slide back thru if it drags in the water. You can't get it back WITHOUT going in. REAL pain, be there, done that. Here is pics. If you have any questions, just PM me.
