A NAUTICAT motorsailer has two steering stations with remote controls to permit steering outside as well as inside. One thing to remember about the remote control is always to return the lever into neutral when changing from one steering point to another. If one remote control is engaged, the other one won’t work. This may…

The wind direction dictates the order in which the mooring lines should be fastened. If the wind is on the bow, attach the bow first, if it is on the stern, the stern first. Loose line ends should, according to good seamanship, be gathered on board, not on the pier. If you have to change…

Aided by the coefficients one can use the distance recorder and the log pretty safely. Unless having made up this table, do not trust the accuracy of these instruments. Try, if possible, to use one and the same measured distance, and remember that the longer the distance and the more carefully you measure it on…

The NAUTICATs are motorsailers, differing from pure sailing yachts chiefly in the greater emphasis on comfort and roominess, and in being equipped with a more powerful engine. Thus the hull shape is slightly more bulky, the displacement a bit greater and the sail area somewhat smaller. This naturally affects the sailing performance to a certain…

When running downwind, attach the kicking strap to the cap shroud, to avoid the risk of unintentional gybing, i.e. when the boom slams over from one side to the other. This may carry away your entire rig, if the wind is strong enough. When running, try to sail “butterfly” i.e. “wing and wing”, or to…

When tacking in light winds with a NAUTICAT you may have to help her turn by releasing the genoa only when you have gained the new tack. I.e., do not loosen the genoa sheet before the turn, but after. The wind on the “back” side of the genoa will make the bow fall downwind, and…

When hoisting, blanket the spin with the genoa. Hang the spin pole on its hook, fasten lift and downhaul, and pull them tight, adjusting the pole into horizontal. The spin pole should be on the windward side of all the forestays, i.e. the opposite side in relation to the main boom. Fasten the spin bag…

The gelcoat used on NAUTICATs will not fade in the sun or by age. However, to achieve maximum durability, the hull needs maintenance. Make sure that there is no sand, or other abrasive substance on the hull, by gently brushing it off with a dry cloth. Then clean with warm water and detergent, using either…

Exterior teak The treatment depends on whether you want the teak to remain dark or become light, “grey”. If a dark tinge is desired, oil the wood from time to time, using either normal teak oil, or special water resistant cleaning/brightening liquids. Before applying the oil, clean the wood with mild detergent to avoid scrubbing…

HAULING OUT The yacht can be hauled either with a cradle on tracks, or by lifting with a crane. If using a crane, observe the same cautions as when launching (drawing “docking plan and cradle”). When applying the slings, make sure they won’t rest on the propeller shaft. CRADLE Preferably store your NAUTICAT in her…
