Moulding shop
The moulding shop is divided into two main areas. In one of them all
of
the
in-house moulding processes are carried out. In the other boats are
completed to whatever stage the customer requires. All hull moulding is now done outside of SAILSetc. Our IOM hulls are made by Al McMeekin using wet lay-up into female moulds in the traditional way. Hulls for Marblehead, Ten Rater and A Class are now made using pre-preg carbon by Reverie Ltd and all come to us with the deck, fin box and mast tube incorporated into the primary hull moulding.

Hull mouldings from Reverie Ltd and partly completed hulls from Al McMeekin are taken to completed stage, or whatever stage the customer requires, in our own workshops. The hull surface is prepared, internal mouldings are added, the foils and ballast are added, and the fittings are added. If required the rc can be installed too. A leak test is carried out on all boats before leaving the workshops and checks are made to ensure a high degree of symmetry, essential for best performance, is achieved Al McMeekin – subcontract boat builderAl has been moulding all our IOM hulls for some time now. While we are without a full time boat builder at SAILSetc Al also adds the remaining structural parts to the hulls, the foils and the ballast. Many of those techniques Al has acquired making advanced model sailplanes are useful on our boats too. With Al’s thoughtful assistance we have been able to make several improvements to the way in which our boats are produced.

has degrees in costume interpretation and technical arts/special
effects, a course which introduced her to working in glass and resin.
From a sailing background she now spends her spare time promoting the
samba culture in the UK and directs her own samba band, Boudica.
Moulding
of component parts is usually done by compressing the reinforcement
materials, which have been wetted out with epoxy resin, between
carefully made 'matched moulds'. The result is a moulding of controlled
thickness which has an extremely low resin/fibre ratio. The fibre/resin
ratio is probably higher than most pre-preg laminates. We were intrigued
to find that fin skins made from high modulus carbon pre-pregs gave a
heavier and much less stiff fin than our own mouldings did.
The whole
area is well heated and well ventilated. Hydraulic jacks and G-cramps
are used for compressing the moulds and low temperature ovens are used
to heat some of the moulds while curing.
All the
boats built at SAILSetc have a builder’s label bonded onto the inside.
It records the names of the people involved in the boat, the design
name, the moulding number and the name of the person for whom it was
built.
