Mast base moving around.

Posted by marno_ss (marno@…>)

Gday Guys,

Shortly after I bought Attitudes (Freedom Express 39), I heard a
strange sound coming from the chain locker. After investigation, I
found the base of the mast was moving about 1/4 of an inch forward
and backward. I went to a friendly boat yard and had the mast lifted
and had a look. The plug looked in good condition, but the inside of
the mast looked a little worn, so we waxed up the inside of the mast
and put some epoxy onto the plug. This seemed to solve the problem
and I cruised from New Jersey down the East coast of the US, to the
Bahamas and the Dominican Republic with no problem. However, during
the first few days of our Atlantic crossing, it started up again. I
tried using a syringe to inject some epoxy through the hole at the
base of the mast, but this didn’t work. We survived the trip to the
UK (I’m so glad those masts are massively overbuilt) and I looking
for a permanent fix.

I was hoping that someone has dealt with this problem before, I have
some ideas but would like to hear from people who have a proven fix.

Thanks

Marno

Marno,

Is the base of the mast bolted to the step with a substantial bolt?
That needs to be there. DOn’t sail without it being bolted. Creaking
sounds from the masts are common. We used to get some noise while at
anchor from our mizzen mast. I assume you’re seeing movement right at
the base? That’s more of a concern than noise alone. It’s been so
long I’ve forgotten what we did to alleviate the creaking. Perhaps
you could try some sort of bushing where the bolt passes through the
step? If it’s bolted and the mast is moving the bolt has to be moving
with it unless the holes in the mast itself are elongated.

Thanks for the reply Dave,
The bolt and bracket are there and seem to be in good shape. The
bolt is off to the side and the mast is moving around it.
I have been contemplating pulling the mast, waxing the plug, putting
a thin layer of fibreglass on it and lowering the mast back down
before the epoxy goes off so that it is a perfect fit.

I had my mast pulled on my 40/40 and had a layer of fiberglass laid
inside of it. We then took the inverted pie-plate base, which had been
covered with mold-release material, and inserted it into the mast as a
mold for the interior of the mast. This worked well and has basically
stopped the creaking.

The base edge of the mast on our 45 had a slight angle to it and therefore did not stand square. We did not realize it until we pulled the mast for a rebuild of all elements and discovered the angle. It was simple to square it up with a small but precise cut. After it was re-installed the movement disappeared.

Marno,

Many Freedoms with the internal plug system suffered from your
problem. On later Freedoms and on boats with problems, they did away
with the internal plug altogether. Instead, the mastbase is supported
with an external mast ring, just like the one on deck. The mast is
held in place with one throughbolt or two shorter bolts. On my F33,
the base ring was over sized in diameter, so I filled the void around
the masts with polyester filler. On my current Freedom, the rings are
just large enough to have the mast.

It’s important that the base of the mast is supported sideways along
its entire perimeter. This is to prevent stress points on the mast.
The bolt(s) are only there to prevent turning.

In stead of fabricating metal mast rings, you could layup something
of epoxy and glass around the mast. Don’t forget the mold release
agent. You can then also glue the plug in place inside the mast.

Good luck

Thanks for the help,
This sounds like a great idea, I think I will create a collar the
same way they do the plugs (bolt and epoxy them into place) and then
fill the gap with spartite or something like that. I’ll make sure to
put some sort of mould release onto the mast first though. I don’t
even need to lift the mast. Brilliant!! So simple that I couldn’t
figure it out for myself before.

I would not use spartite. It’s not suitable for supporting
freestanding masts since it is only durometer 60, which is too soft
to prevent movement. Spartite themselves also advice against using
standard Spartite. You can use commonly available PU resin of
durometer 90. It’s much cjeaper also that spartite. You can get it
in specialized hobby mold shops or suppliers for casting concrete
statues and that sort of thing.

I used common vaseline succesfully with both Polyester, Epoxy and PU
resins as a mould (mold?) release agent.

Indeed the Plasticine is ideal stuff to make smooth casting molds
and seal gaps.

Hello,

I had the same mast rotating problem with my Freedom 44, 15
years ago. The main mast rotated about 15 deg when I was sailing
downwind in heavy air wing to wing on the way back from Bermuda.
I was lucky enough to make it home, under very shortened sail
on the main, without the mast totally coming out of the step (very
tight boom vang and jib/main halyards…)

After talking to TPI at that time (Paul Miller and Brian
Barer) I followed their recommendation for best solution for any
fixes of that problem on all freedoms. Even if you have bolted the
mast to the mast step the amount of carbon fiber will not be enough
to prevent the bolt from eventually “wearing out” the fibers and
getting loose…

1- On the inside of the mast, laminate 2 3/4" thick by 2"
high by 4"long aluminum plates, following the curve of the mast,
diametrically opposed to each other. Use some filled (high strength)
epoxy for bedding and filleting the aluminum plates. Then use
biaxial, 4" wide, glass strips all around the inside of the mast to
glass in these 2 aluminum plates. I would recommend at least 3 layers
of 17oz type of materials.
2- Drill and tap each plate to receive 1/2" SS bolts that will
match the holes drilled in the outside aluminum bottom plates holding
the base of the mast.
3- Put the mast back in place and tighten the bolts in place
using lock washers. Make sure that collar is tight all around.

Depending on the situation at the bottom of each mast it might
be easier to take that collar off to match the holes properly and
then put the collar back in. (make sure to mark everything properly
before removing so it all matches…) Depending on proper access with
the mast in place
it might be easier to use one 1/2" stainless steel threaded rod to go
through with a couple of lock nuts at each end.

Neither one of my masts ever turned again after that fix. It
might sound a bit complicated but it really is not if you have a good
fiberglass man…

PS: Friendly reminder, Frog-Kiss is still on the market. She is
beautiful and has many proven offshore single/short handed miles,
including 2 overall fleet victories in Bermuda 1-2. She is better
than new and probably would cost over $3/4 million to duplicate
today.
She is presently in Virgin Gorda, BVI, and I shall bring her
back to Newport in the spring.

That’s great info!
Could you post a diagram or link to help us better visualize the fix?
