Now you can cut out the hatch for the front fins in the floor of the hull. The measurements for this
please take out of the building plan or make the size yourself that you can fit your hand in to make
adjustments. Cut it out along the fat line and lay it over the hull floor so that the two fat black dots lie
exactly on the large markings for the fin shaft. Then clearly mark with a drill the corner points of the
hatch and drill these through with a 1.5mm bit. Then link these corner holes, as with the stern hatch,
and cut them out the same way. As with the stern hatch, apply scrap pieces on the inside of the hull to
the edge of the hatch so that the hatch lid cannot fall in.
Then you apply scrap pieces to the lid, as per the drawings below, so that it can be hooked up and
clamped in like the stern hatch.
The fins and connections will be fitted later.
Assembly of Pressure Tank
Before the two half shells of the pressure tank are glued together, they need some preparatory work
which is a lot easier when done beforehand.
Preparation of Lower Shell (11)
First cut off the rough edge of the lower shell. Make sure you know which are the front and the rear of
this part. The end with the slightly rounded floor is the rear, the end with the wedge-shaped bulge is
the front. Now the holes for both stern tubes are marked and drilled out to 7mm diameter. For this, first
of all mark a vertical centre line on the outside of the rear wall. Then draw a line parallel to and 5 mm
from the upper adhesive edge and mark the centre points of your holes on this parallel line at a
distance of 18mm from the central vertical line. Start drilling with a 2mm bit and increase the hole
gradually whilst ensuring that the central point of the hole is maintained.
