I acquired from somewhere a roll of industrial-type clear plastic stretch roll. The kind like you can have your suitcase wrapped up in at the airport. This roll is about, say, 15-18 inch in width.
When I drop my mast, I wrap up my mast with this, starting at the tang and wrap round 'n round to the mast base, including all lines, traps, shrouds in the wrap. Takes literally a minute to do and all your lines are tightly wrapped up with the mast. Nothing needs to be tied, nothing is flapping around, no lines getting caught on anything. Once the H16 is on the trailor, the mast quickly and easy is lifted/moved onto the trailor. When travelling - your mast and all lines are protected from any road grit that you may encounter.
When I want to step the mast, I hook up H16 mast base/step key, then run a razor knife down the length of the mast in the main sail groove along the mast. The wrap comes off in a jiff and the shrouds quickly available to attach. Before I do the wrap (as above) I bungie my 4 trap lines to the trap base so they stay in place and out of the way (same for main and jib halyard). In this way, when you unwrap the wrap, only the shrouds are loose and ready to install. With the mast up, I quickly attach the traps and it's time to sail!!!
Not rocket science but a quick and easy thing to do that is fast, efficient and makes moving/transporting your mast and lines super easy. No headaches.
PS No, I don't know where you can buy this stuff. The roll I have looks like it will last for years to come.
Hope others may find this useful.
Cheers to all
