is possible to simply caulk and seal around the wedges and partners but
this is unlikely to be very satisfactory and every time you need to
re-step the mast or adjust the wedges it will all have to be raked out,
and then resealed.
The next simplest method is to use a rigging and mast boot tape.
This is the self-amalgamating type of tape which can be bought in wide
It is waterproof flexible and extremely simple to wrap on.
If that sounds too easy to be true, well it probably is.
it does need to be wrapped on to something ,it is fine around the mast
wedges but getting it to cover the seam between the wedges and the deck
is the problem.
It will also show dirt and tends to peel after
time, and it isn’t all that cheap either, especially as you will need a
couple of rolls for the average mast diameter.
The next best DIY solution is the rubber mast boot.
These are made using inner tube material, if you can find any theses
the inner tube and hose clamp system works well if done right it does
look pretty ugly and the rubber will degenerate over time in sunlight.
option is to use a combination of the above methods, then
with a wraparound cover of material such as ‘sunbrella’, which could
simply be attached with a ‘velcro’ strip.
But then if you are going to the trouble of cutting and sewing a cover
why not make a proper mast boot in the first place.
The top of the mast boot attaches directly
to the mast.
The bottom edge will also need to be attached to something.
So you will need a deck ring or flange.
deck-ring should be well clear of the wedges and with a grove or lip
into which the bottom of the boot is securely fastened.
will also be of the same profile as the mast, circular for a round
mast, oval foe an oval mast and be positioned so as to allow the mast
boot to have a runoff slope of somewhere in the region of 60 degrees.
