A 25' steel tape measure is usually stiff enough that it can be threaded the length of a boom after which one can affix a small "messenger line" to the outboard end and draw that back through the boom as the tape measure reals itself up. I have used this method on our 17' boom and on a friend's 15 foot boom with little difficulty. If you don't have messenger line aboard odds are you may have some dental floss which works well (BTDT).On my Pearson sloop 2 reefing lines go through the boom exiting both ends. Unfortunately one came out and I cannot figure out how to feed it back through the boom.
Any ideas??? I have tried feeding it through but no go... it bunches up...
Thats a good explanation "one step back, two steps forward"Same thing happened to me. We have outhaul, topping lift and 2 reefs all coming through the boom.
When the second reef line came out accidently I just tied 2 messenger lines to the first reef, pulled it out of the boom, and then used the lines to re-run both reefs. Sort of 1 step backward, two steps forward, but it was still only about a 10 minute job.
