The FAO's International Standard Statistical Classification of Fishing Vessels by Vessel Types (ISSCFV) categorizes fishing vessels primarily according to the Main Fishing Gear Used on board (e.g., Trawlers, Purse Seiners, Gillnetters, Longliners, Trap Setters, Dredgers, and Multipurpose Vessels).

According to marine boat construction standards (Bureau of Indian Standards / BIS), timber used for marine hull planking and framing should be seasoned to an equilibrium moisture content of 10% to 18% (typically 12%–15%). Timber seasoned below 10% swells excessively in seawater, while timber above 18% shrinks and undergoes dry rot.

One international nautical mile is defined as exactly 1,852 meters ($1.852\text{ km}$), corresponding approximately to one minute ($1'$) of latitude along any meridian on Earth ($1\text{ NM} = 1.15078\text{ statute miles} = 1.852\text{ km}$).
