At the very least, grasping the shipʹs position is
indispensable to prevent grounding. Since it is
navigated only by students, it is thought that this
navigation was carried out with considerable strain
andwascarefullyperformed.Thus,itisthoughtthat
students utilized the bow target etc. effectively. The
anchoring position shows the result of grasping the
shipʹs position. Except for two instances, the
anchoringpositionwascontainedinthecirclewithin
a radius of 130 m of planned anchoring position as
shown in Fig. 8. It can be said that anchoring was
performedwithsufficientaccuracy.

Moreover, the instructorʹs comments are relayed
below from a viewpoint with “the acquisition and
improvement in the various navigation skills by
implementation of anchoring navigation,” which is
the purpose of the training: “Planning performed in
advance has taken considerable time and efforts
including the exchange of opinions in a team,
therefore,itseemsthatanunderstandingdeepened.”
“Althoughtherewasasceneforwhichitdependson
the others in a team too much, the consciousness
which heightens the capability as a team being
consciousofBRM/BTM wasableto see.” “Although
there was a scene where the distance with
a fishing

continued carefully and give‐way shiphandling was
carried out appropriately.” These comments show
that the learning effect increased byintroducing the

evaluation as a whole, it is thought that students
evaluated severely. While two instructors’ average
score was 19.4 points (36 points full marks), the
averagescoreofself‐evaluationwas18.6points.The
difference between instructorʹs evaluation score
and
the self‐evaluation of procedures involving leaving
up the anchor, gradually decreasing speed, and the
anchoring procedure, were large. In the self‐
evaluation of the leaving up the anchor procedure,

instructorʹs evaluation. Approximately 44% of
students provided a self‐evaluation lower
than the
instructorʹs evaluation. On the other hand, the
instructorʹsevaluationscoreandself‐evaluationscore
were almost the same for the following evaluation
items.

out that items that received a high instructorʹs
evaluation were evaluated more critically via self‐
evaluation.

The self‐evaluation scores of one of the students
were as good as the instructorʹs evaluation scores.
Moreover, the comment of self‐evaluation was

appropriately was high. As mentioned above,
