INLAND ONLY Two power-driven vessels are meeting in the situation as shown in illustration D037RR below. What does one short blast by vessel "A" mean?

Correct Answer: Option C — "I intend to leave you on my port side"

Under 33 CFR 83.34(a), one short blast signifies an intention to leave the other vessel on the port side. This is the standard signal for a port-to-port passing arrangement in inland waters when vessels are meeting in a head-on or near head-on situation.
