Question 1

What type of anchor is generally best suited to a soft mud or sand seabed, and why?

Accepted Answer

A plough-type anchor (such as a CQR or Delta), which digs in progressively and resets well if the direction of pull changes, making it a strong general-purpose choice across most seabed types including soft mud and sand Plough-type anchors are popular general-purpose choices precisely because they perform reasonably well across a range of seabeds including soft mud and sand, and they reset themselves reasonably well if the vessel swings and the direction of pull changes — a real advantage over anchor types that hold well in one specific bottom type but struggle to reset if the pull direction shifts.

Question 2

You need to make up a mooring line to leave permanently rigged on a cleat. What is the correct way to secure it so it can be released quickly under load if needed?

Accepted Answer

A full turn around the base of the cleat, then figure-of-eight turns across the horns, finished with a locking hitch — this holds securely under load but can still be freed even when the line is under tension A round turn plus figure-of-eight turns finished with a locking hitch is the standard cleating method — it grips securely under load through friction, but because it isn't a jamming knot, it can still be released even when the line is under real tension, unlike a line simply wrapped or a knot that jams tight.

Question 3

Why is nylon rope generally preferred for anchor rodes and mooring lines, rather than polyester (Dacron)?

Accepted Answer

Nylon stretches significantly under load, absorbing shock loading from waves and snubbing — exactly what's needed to protect ground tackle and cleats from sudden jerking loads Nylon's elasticity is the whole point for anchor and mooring use — it stretches under a sudden load (a wave lifting the bow, a gust snatching a mooring line) and absorbs the shock rather than transmitting a sharp jerk straight to the cleat or anchor. Polyester's low stretch is actually why it's preferred for halyards and sheets instead, where you want minimal stretch for sail control.
