| LOWERING THE MAST AFLOAT – SOME GUIDELINES AND A SUGGESTED PROCEDURE. |
| [Note: In addition to the embedded photos
on this page [apologies for poor quality] there is also a separate page
of illustrative sketches - click here to
view]. When cruising in the Wanderer it is sometimes necessary to negotiate low bridges or other overhead obstructions which entail lowering of the mast. Catastrophic rig failure or other accidents while afloat may also require the mast to be taken down. Even when attending relatively leisurely day cruises for example, round Hayling Island or the Norfolk Broads, low bridges will be encountered. The skill of mast lowering afloat, in a systematic and controlled manner, is one of the many ‘tools of the trade’ that an accomplished sailor should have in his or her ‘bag’. Time spent practicing and refining this skill will be of great benefit and excellent investment for the future. The author describes here his own particular approach to lowering the mast while afloat but is appreciative that alternate methods may very well be found more suitable for other individual sailors and that each will inevitably develop their own particular method. The description given here however should well provide those Wanderer owners, yet to tackle this issue, with a foundation and set of guidelines on which they can base and develop their own method. I agree that the thought of dropping several meters of mast, boom, sails and standing rigging into the boat while afloat would seem a little daunting. It demands attention to detail, early planning and an organised boat. However once a system has been evolved, refined and learned plus the acquisition of some additional helpful equipment, then the scale of the task dramatically diminishes, becomes much less intimidating and finally second nature. The method described here should be
generally applicable in most situations where the boat is moored for the
actual mast drop. Little adaptation is necessary in order to evolve a
procedure for use while continuing to make way and drop the mast without
the need to stop. This is probably the ultimate and most efficient mast
dropping procedure. For the purpose of the description here I have assumed that there is a crew on board and that the boat has a furling jib and an outboard engine attached. The additional equipment mentioned early refers to:-
The modification comprises a single block with becket attached to the stem head fitting using the pin furthest forward [see inset photo] and a further single block fitted to the forestay eyelet. A line of sufficient size and material [I use the same as for halyards] is tied to the block on the stem head and then run through and round the forestay block before being returned round the stem head block and routed back into the boat for cleating off. I cleat to the large fitting on the foredeck just in front of the mast and stow the remainder of the line coiled in a bucket or siimilar. It is possible to run the line aft if required [Anglo Marine offer this as an option]. The inset photo should make all this very much clearer! Having got the extra equipment out of the way I think we are now ready to describe the basic mast lowering method. It assumes you have the above extras, a crew, furling jib and an outboard. The sequence describe is that used by myself but, of course, can be customised to suit.
After mooring furl the jib. Remove and safely stow the mast foot pin. Drop the main, release the kicker, detach and lay the boom and flaked mainsail orderly to one side. Tidy all lines. Raise the board leaving just a little down for some ‘bite’ when the outboard is deployed. Lower outboard and turn fuel on. It is much easier to do these action now than when the boom, jib, main and mast are cramping your style! Place the mast crutch toward the rear of the boat. Check that there are deliberate figure of 8 knots in both main and jib halyards to prevent them disappearing up the mast! Release the rig tension by opening the Highfield lever leaving the jib wire halyard attached to the lever’s ‘hook’. Ease the forestay tension by releasing the ‘new’ forestay line a little so it just sags. This is important if the mast foot pin has been removed as we don’t want to allow the mast to be able to move forward out of the track! This will now allow easier insertion of the mast pivot pin through the tabernacle and mast [note that you are not supposed to sail with this pin inserted!], some ‘jiggling’ may be needed. The forestay line can now be re-tightened if required. Helm and crew have a final check round and tidy up before they are ‘partitioned’ by the mast barrier! This will be the last time to easily check or stow any item before the boat becomes very cramped. Check aft in case someone has moored there or something has encroached into the space where the mast is about to be dropped. As mentioned before there will be about 4 mtrs of mast and rigging hanging out the back of the boat after dropping the mast!! If all is ok then proceed to drop the mast. With all final checks complete the helm can start the engine, check for other traffic both on the river and passing under or preparing to pass under [in both directions!] the bridge, cast off [watching the mast overhang does not get caught with anything on the bank!] and proceed out into the river where he should align the boat with the correct approach for the bridge [centre of arch/span]. Engine throttle may also need adjustment especially if going against a strong flow.
The crew locates and passes the helm the forestay line and he/she starts the mast up by lifting it clear of the crutch ‘V’ and taking up the tension on the line. The crutch is folded up and temporarily stowed out of the way. As the mast continues to come up the crew steadies it to keep it amidships while pulling in the jib halyard, at a rate equal to the mast progress, though the mast foot blocks to prevent the jib falling out of the boat. Both crew and helm continually check for potential snagging [shrouds getting caught round the tiller extension, boom or outboard arm are all popular and fun!] and the crew maintains tension on the jib halyard to prevent it dropping. As the mast approaches a near vertical position the crew checks the alignment of the mast foot with the slot in the mast foot plate and makes any necessary guidance adjustment. Once the mast is fully vertical and the foot engaged in the plate the crew places the jib halyard loop over the Highfield lever ‘hook’, cleats of the forestay line, and inserts the mast foot pin through the holes in the floor plate - phew. At this point the mast pivot pin should be removed and stowed before any increase in rig tension is applied. The jib is effectively already hoisted and so the Highfield lever can be positioned on the appropriate notch and the lever closed. The now slack forestay can be re-tensioned using the line and cleated off. All that remains is to raise the main sail [prevailing wind permitting] attach both boom and kicker before finally raising and securing the outboard [check fuel off?]. Final check and adjustment to rig, centre board and boat generally before casting off and continuing your passage ......... to find, just round the next bend in the river there is another !*!*!*! - you know what! Well at least you now have one mast lowering under your belt, so to speak. I strongly suggest that you practice and develop a method that is suitable and easy for yourself and crew. Although the above may seem somewhat daunting at first with practice and effort it will become second nature eventually and I hope the above method will provide the impetus to try and to develop your own mast lowering procedure.
