THE STRIP PLANK
METHOD OF CONSTRUCTION
For this, we will use several
different Selway Fisher Designs as examples but mainly
the 17'9" INDIAN RUNNER steam launch.
A. The chipboard moulds
(sectional shapes) are carefully erected onto a simple wood strongback.
B. In this case, the internal
stem has been laminated but may be made up from solid wood -
note the hog which is laminated in situ on the moulds.
C. Planking starts - in this
case from the gunwale until bending the wood strips becomes too difficult - in
some cases, depending on the hull shape, you can plank right from the gunwale up
to the hog.
D. In this case, planking was
stopped at the bilge and then started again from the hog to meet the previous
planking - this means that some of the strips have to be tapered at their ends.
If the builder prefers - to make sure that the planking can be done without the
need to stop and change direction - the first plank can be positioned at the
bilge and allowed to lay along the "great circle" route - planking
then continues above and below this first plank.
E. In some designs,
other internal items are fitted before the hull is planked - in this example, a
bilge stringer has been laminated in situ on one of our 25'6" Snow Bunting
F. Once planking is complete
and cleaned up the hull is sheathed in glass cloth or
G. External wood keels/skegs
can be laminated on the hull whilst it is still upside down, cleaned up off the
boat and then refitted before the hull is turned over - the example above is one
of our Edwardian 26's.
H. The hull with stem etc laminated
over the glass sheathing and turned upright.
I. The finished
boat - above the 17'9" Indian Runner and below the 25'6" Snow Bunting.
