41. Template ==> A mold or pattern. Sometimes made of plywood or paper.

43. Welding ==> Fusing together two or more members with electric arc or by other means.

45. Winch ==> A small hoisting device; used in pulling lines or cables in handling cargo. Can be hand, air motor, electric, steam, engine, etc...powered
46. Sheer ==> Curvature of deck in a fore and aft direction as seen in profile.

48. Hatch ==> An opening in a deck for passage of cargo, etc
49. Floor ==>The lower portion of a transverse frame, usually a vertical plate extending from center line to bilge, and from inner to outer bottom.
