Thrusters can be positioned outside of
the boat centre line, however, all
positioning measures must be
considered
Ensure to have a minimum
of 100mm space around
the thruster installation to
have service access
Important
When cutting use a suitable
guide tool to ensure correct
cutting angles.
Measurement tools can be used
to aid marking transfer lines. Do
not exceed the minimum cutting
border indicated on the yellow
label on the SRF flange.
Marking and Trimming of SRF Flange
EN
1. Identify the location of the thruster considering space required for installation, operation and future maintenance.
2. Mark the keel centre line on the inside of the hull. Flip the SRF flange upside down and use the internal surface to mark the hull for cutting the
thruster hatch.
(NB: Ensure the mould is centred.)
3. The SRF flange must sit so the two side rails run flush with the length of the hull. To do so the SRF flange tabs must be trimmed down to match the
hull profi le curvature.
(NB: Consult a naval architect for methods to transfer the hull profi le to the SRF flange. DO NOT cut the SRF flange length
edge.)
4. Cut the hatch door. The hatch opening must be cut at an angle of 45º on three sides and 30º on the bow face. This allows any water forces hitting
the hatch while closed to be absorbed by the hull, not the thruster.
(NB: Use a suitable cutting tool able to be set to the desired angle. If cutting
from outside the hull drill 4 holes from the internal marked corners to see the required profi le from the outside.)
