USCG Deck General

A mainsail is controlled by halyards for hoisting, sheets for trimming, and downhauls for tensioning the luff. An 'uphaul' is not standard terminology in sail handling; it is typically associated with rigging for spinnaker poles or specific deck gear, but it serves no functional purpose for a mainsail.

Consulting the M.V. Grand Haven Guidance Manual, the hydrostatic tables and loading curves for the specified grain test weight of 33 lbs require 1070 tons of ballast in tank No. 5 (P & S) to achieve the target draft of 17'-00" forward and 22'-06" aft.

The Master remains legally responsible for the vessel's safety at all times. A pilot acts as a specialized advisor providing local knowledge regarding navigation, hazards, and port regulations. The Master's authority is never superseded by the pilot's presence, as established in standard maritime law and USCG bridge resource management.

Federal project depth refers to the design depth to which a channel is authorized to be dredged by the U.S. Army Corps of Engineers. It does not guarantee the current least depth, as shoaling or silting may occur between dredging cycles, making 'design dredging depth' the technically accurate definition.

Transferring the watch during a collision avoidance maneuver is strictly prohibited under standard bridge resource management practices. The officer currently in charge has the situational awareness and mental model of the encounter; interrupting this process during a critical maneuver significantly increases the risk of human error and potential collision.

Load line markings are governed by 46 CFR Part 42. The 'S' mark represents the Summer load line. Because the St. Lawrence River is considered salt water in the context of international load line conventions, a vessel may legally load to its summer salt water marks while in those waters.
