(1) Bilge keels in app. hull tests (MARIN) are named A; bilge keels used in “bare hull” tests (FORCE, IIHR, INSEAN) are named B.
Definitions of the hull and the appendages can be downloaded here:
5415 Hull (Appended)
5415 Propeller Openwater Data
5415 Appendages/bilge keels A (Appended hull)
5415 Hull (Bare)
5415 Bilge keels B (Bare hull)
5415M Hull (Appended)
5415M Propeller
5415 M Hull (Appended w correct stabilizer position)
5415M Propeller position
The difference between the files 5415M Hull (Appended) and 5415M Hull (Appended w correct stabilizer position) is that in the latter file a small correction of the stabilizer fin position has been made to obtain the correct fin position according to model test setup.
