Loose, not on moorings or towline.

Coaming is any vertical surface on a ship designed to deflect or prevent entry of water. It usually refers to raised section of deck plating around an opening, such as a hatch. Coamings also provide a frame onto which to fit a hatch cover. The protective metal sheeting or plating protecting against water entry into ventilator shafts in large ships is called a coaming as it suits this purpose. The term was borrowed by the aviation industry to refer to a low rim around the opening for an unenclosed cockpit. In addtition, coaming is the vertical surface rising from a hatch, as in hatch coaming, which forestalls the ingress of water and provides a sealing surface for the hatch cover. Coaming also refers to the raised structure around the cockpit of a kayak.

The term "freeboard" has multiple meanings, depending on the subject area. In sailing and boating, freeboard[1] means the distance from the waterline to the upper deck level, measured at the lowest point where water can enter the boat or ship. In commercial vessels, the later criteria measured relative to the Ship's load line, regardless of deck arrangements is the mandated and regulated meaning.[2] In yachts, a low freeboard is often found on racing boats, for weight reduction and therefore increased speed. A higher freeboard will give more room in the cabin, but will increase weight and may compromise speed. A higher freeboard also helps weather waves and reduce the likelihood of green seas on the weather deck. A low freeboard boat is susceptible to swamping in rough seas. Freighter ships and warships use high-freeboard designs to increase internal volume and also allowing them to satisfy IMO damage stability regulations due to increased reserved buoyancy.

Any of the 'stays' that hold up the mast that are mounted to chain plates that are on the sides of the boat or athwart ship. This excludes the fore stay and the aft stay which are always stays and never shrouds.

Stays (nautical), the heavy ropes, wires, or rods on sailing vessels that run from the masts to the hull.
