To keep the mast from toppling over, an array of rods, cables, ropes (lines), and wires are attached at various spots on the mast and run down to the bow, stern, and sides of the vessel.

Diesel engines run hot because of high compression and therefore need to be cooled. Fortunately, ample cooling is readily available from the water the vessel is sailing in.

Winds can be gentle, hardly felt, like zephyrs flitting about in a local area, or they can be vast movements of air moving swiftly across oceans and continents at low and high altitudes.
