Mooring fittings

MOORING FITTINGS

As with anchoring gear, mooring fittings can be easily and seriously underestimated. Most modern vessels appear handicapped in both. This may be a result of the explosion of marina developments over the past few decades where now boats are expected to spend their lives in a sheltered berth, rather than hanging on a mooring or alongside a more exposed wharf. Certainly builders are catering to the former need.

In our experience we have found that bollards should be sized for, and of adequate strength to allow the vessel to be comfortably “towed” from or alternatively to tow another vessel with complete confidence.

Foredeck layout

We fit two types of bollard: the double bitt and the crucifix post. In our typical fore deck layout we fit either two double bitt bollards offset from the centreline or one double bitt bollard on the vessel centreline. The fore deck on a Watson vessel is always protected, either by bulwarks or as a well deck as shown above. This provides a safe working space with no risk of lines being drapped or lost over the side; inevitability wrapping around the propeller!

Forward mooring lines are always used via fairleads, with the bollards raised up on plinths for correct alignment. The fairleads themselves are made from large round section pipe which ensures that where "laid" rope is used it will not catch in the lay of the rope and will always easily slide over even at the sharpest angle.

Fore deck bollards

In the event that the vessel ever requires to be towed a bridle can be made up with an end secured to each bollard and the tow line attached to the bight of the bridle.

Bollard fore deck

As the options for "off the shelf" fittings is seriously limited in the larger sizes, we custom make; fabricating our bollards from stainless steel. Holding down bolts are welded into the plinth; never fastened through the main weather deck and are of a strength calculated far in excess of any load demand that may placed on them for towing. 

Aft corner post

The crucifix type is fitted at the transom corners and also vessel fore shoulders for securing spring lines. They are welded to a deck doubler pad and bulwark cap rail and form an immensely strong tie off post. They provide a tying off point at bulwark or waist height so there is no hands and knees work when berthing. The mooring line can be lead directly to the marina or wharf or run through one or other of the fairleads fitted into the bulwarks. 

The pin through the post is not for tying around but is to prevent the mooring line slipping up off the post. The correct way to use these is with an about turn (twice around the post with the line) and two half hitches to secure. This is “fisherman style” and allows for the line to be pulled up tight yet easily let go; so a sharp knife or axe is never needed for untying!

Corner post outboard

The type of fairlead we install is the closed type rather than open which can prove to be unreliable when the line may become slack in a surge and jump out. The open area of the fairlead is made large enough to allow the eye of the mooring line to fit through. Excess mooring line can be gathered up and hung over the post keeping the deck clear.
