Selden Mast Revisions
During the life of the class the MSCA has continued
to work closely with the builder, Ovington Boats and
their key suppliers of critical components to ensure
the class continues to be the best it can and to revise
any items that may suffer excessive wear, tear and breakage.
All this whilst at the same time ensuring
the strict manufactures one-design principals are preserved
ensuring a fair and level playing field for all competitors.
Over the years a number of minor performance neutral
changes have been made and these are documented in the
There have been a number of issues reported
to the committee over the years and these are dealt
Mast Head Crane
There has been a small number of reported
issues with the head crane pulling out/rotating causing
a split in the mast tube at the tip.
The S2/S3 Carbon head crane design was
upgraded some 8 months ago. The motive for this was
to improve on the current design which had a tendency
on occasion to fracture the mast tip. So by lengthening
the spigot and reducing the leverage effect of the crane
itself we believe this new design to be a major improvement
of the previous. (See
a series of images featuring the new crane - showing
how to rig a 2:1 halyard).
This modification has already been filtering
into production of the latest masts.
There have been a number of reports that
the plastic mast track has fractured at the point where
the batten pockets impact against the track. We have
sought to resolve any future problems and put in place
a solution for any who have the problem in the future.
is also quite a bit on the forum about this.
The original Series 4 track was robust
but was always too large across the flange to fit the
Series 3 section and had to be replaced with a dedicated
design track. The Series 3 track we (Selden) believe
became available in 2003 and was produced via a new
supplier. Several years later Selden terminated the
relationship with this supplier. A new supplier started
to produce using a new die and to the Selden specification.
Selden's supplier has modified his tooling
to ensure that the extruded polymer will always have
web walls nearer to the thicker end of the Selden drawing
tolerances. We believe this will provide us with a product
that’s less susceptible to web distortion coupled with
thicker web walls will hence be generally tougher. The
specification of the plastic used will also be adjusted
to make the track less brittle.
Selden will also be making "repair
kits" of spare track and the appropriate adhesive
available to Ovington Boats (Northern Hemisphere) and
the AUS dealer (Southern hemisphere). These kits will
be available free of charge to any owners who may have
a breakage of mast track.
If you have a mast track failure then
there is a free kit available to fix it ...
IF YOU ARE IN EUROPE OR NORTH AMERICA:
1) Take a photo of the broken track
2) Email the photo to firstname.lastname@example.org
with your address and a kit will be shipped direct from
IF YOU ARE IN AUS or NZL
1) Take a photo of the broken track
2) Email the YOUR LOCAL dealer who will have kits that
have been supplied by Selden. This means that you should
get your solution quickly regardless of location.
Mast Tip Breakages
There had been a number of reports that
there had been an excessive amount of mast tip breakage
and there was a concern that there may be a problem.
Upon further investigation it has been established that
the level of mast breakage is less than 1.5% of the
fleet per year and this is well below the failure rate
of typical performance dinghies.
In addition when we pushed into the details
of those breakages it was established that in most cases
the boat had been inverted in shallow water and the
mast had hit the bottom of the seabed and that had caused
the failure. No dinghy mast will sustain being dug into
That said we are seeking solutions to
make the class even better and cheaper to sail so two
suggestions have been tabled:
1. Toughen the top mast
– so adding more safety factor. Selden believe this
can be achieved by changing the bend characteristics
Plus side – potentially have fewer breakages due to
capsizing or general miss-use.
Down side – slight weight, slight change to the bend
and addition cost
The MSCA International committee has
moved against this as it would create two "types"
of mast within the fleet which would be undesirable
and this overrides the benefits to a minority.
2. Make the top join a dry join
- currently the Musto Skiff mast is manufactured in 3 parts
(2 joins). The bottom join by the spreaders is a dry
join and the owner may separate the mast at this point.
Currently the top join is glued. If this join is also
a dry join it would make it easier and cheaper to replace
just the tip section should this get damaged.
The intention is for Selden to produce
a prototype mast that will be fully tested. If this
test is successful then the MSCA International committee
will be supportive of this change and will put it to
member vote in October via the on-line survey.
The MSCA would like to thank Ovington
Boats and Selden for there attention on these matters
and the resulting continued minor improvements to the
specification to keep the fleet sailing low cost robust
