I got fed up with all the bolts and nuts getting caught on things and I'm afraid some day I'm going to rip something, so I finally decided to stow my MRS where it won't interfere.
I bought two 4 foot long by 8 inch diameter sonotubes. (Did you know sonotubes of the same diameter can nest inside each other? I suspect it's due to either magic or a tapered diameter.)
I wanted to get the 6" tubes - I think the poles will all fit - but all they had were 8".
Anyway, it needs to be juuuust over six feet long to hold the MRS pole itself and its hardware - so about 74-75". I slipped one inside the other, with about 27" exposed, and taped the seam.
So it holds:
- the 74" mast-raising pole
- the pedestal crutch
- the pedestal crutch extension (custom - for clearing the bimini)
- the baby stays
