There is a difference between the most common knots seen on a ship, the ones you need to know to pass the AB exam, and the best or handiest knots to know.
Here are a few that will help you work smarter, not harder if you know when and where to use them. And the ones I use most often.
TRUCKER HITCH - For bundling pipe or rods, etc. lashing down tarps and cargo. You gain mechanical advantage.
ROLLING HITCH - Better than a clove hitch when tying something that will come under strong tension, or suspending. It’s adjustable, use multiple turns. Examples are tying up a cargo hose TO a rail, or adjusting tires/fenders over a rail. A Clove can bind so tight you can’t get it undone!
TIMBER HITCH - For pulling pipe or something similar out of a hatch or hole (with extra Half Hitch to hold it vertical), and tying a TO cargo hose FROM a rail (tie the Timber Hitch to hose first, then adjust height with the Rolling Hitch on the rail). For lateral pull and tension and won’t slip.
HEAVING LINES - Avoid this embarrassment when everybody on the ship is looking at you!
Coil your heaving lines like a cowboy coils his lariat/lasso. There is a reason cowboys do this! DO NOT “bundle” them “army-style” or else the next time you throw it, it will tangle and want to figure-8! (This annoys me endlessly! So I make up a personal heaving line that only I use)
Use a bowline with a slip to haul heavy hawsers aboard with the heaving line, then you can quickly move it out of the way so it doesn’t get pinched when you drop the eye on the bitt, or else you’ll have to cut it loose if it goes under tension.
~When lashing down, when possible put a full round turn on the object you are lashing down. It adds lateral stability. Instead of this, "/ " you have this “/O” .
~Know how to tie a pilot ladder to the deck properly. (A series of half hitches in the SAME direction)
~Know how to eye-splice and end splice. (…and take that tape off the strands when you are finished. Don’t worry about the fuzzy fray, it keeps the splice from slipping and adds a bit of chafing gear to the eye)
~Cinch up knots by “whipping or snapping” the line, not buy pulling in it. then it gets tied tight by you putting a SHOCK load on it, not a STATIC load on it. Use physics to your advantage and not having to “muscle” it tight.
~*Style points for tying a TUGBOAT BOWLINE in under one second, being able to lasso a bitt, and knowing how to tie a HANDCUFF KNOT, and other fancy knotwork. I.E. Turkshead knot bracelet, holy cross necklace, monkeys fist keychain fob, bloodknots on the ties of your hoodie…
Cheers!
