CAUTION
Where it is necessary to cut holes (e.g. for cable routing and
instrument mounting), ensure that these will not cause a hazard by
weakening critical parts of the vessel’s structure. If in doubt, seek
advice from a reputable boat builder.
1. If appropriate, use the template provided near the back of this book
to mark the intended location of the Bidata instrument.
2. Use a tank cutter to machine an 85 mm (3
3
/
8
in) clearance hole for
the instrument.
Note: If you do not wish to use a tank cutter, the hole can be machined
using a hole saw and a file.
