If you want to tow with the
model, you must modify the tow post arrangement to enable it to
be used for proper towing. A full description follows
below on how to accomplish this.
The
following information came from
Alan's Boatyard.
The
modification to the towing post to enable it to be used for
proper towing is based on the unit 'Paul Freshney' built and
describes in the Model Slipway "Wyeforce" Kit review in Model
Boats Magazine December 1996.
The brass tube used for the main central unit is approximately
the same diameter as the white metal and wood dowel supplied (in
the kit) being 5/8" OD. I used the KS Metals brass tube No:
KS143 The Outer tube fixed to the hull being KS: 144 (21/32"
OD).
The
143 being a sliding fit inside 144. A bolt was used to lock the
two tubes together. The supplied white metal cross pieces (shown
dark blue) were used, but I first drilled a hole through them
for the clamping threaded rod (red). The two outer vertical
posts can either be 'as supplied' or use 143 brass tube. The
complete assembly was fixed together with slow setting (2 hr)
Araldite, By using slow setting adhesive it is possible to
check everything is aligned before the adhesive sets. Once set
and cleaned up the actual swinging part of the tow post was
fitted as normal. The lower (144) brass tube is splayed at its
bottom end and glass fiber tissue/resin used to fix to the hull.
I also reinforced the

deck where
the tube passes through it, by adding a wide deck beam across
the hull. The two outer vertical tubes simply drop into
holes in the deck and fixed. The holes being blanked by
plastic sheet underneath. When towing I put a cord JUST
round the centre vertical post (brass tube), with a large loop,
which I find works well, the swinging tow arm just moves freely.
