What makes this rig so suitable for the peculiar and varied purposes of a yacht's boat is, that, with mainsheet and peak halliards kept in hand, it gives such absolute control over the pace and direction of the boat at a moment's notice. In whiffing round the rocks after pollack, for instance, in a flawy wind, by lowering and raising the peak, and easing off and hauling in the mainsheet, it is easy to maintain a perfectly level pace of two or three knots. In a squall, or in going alongside a ship or a landing-place, the peak can be dropped and the boat eased or checked at once without becoming unsailable. This constitutes, in my opinion, a very important advantage over the standing lugsail, of which, of course, the peak cannot be lowered. A downhaul should be attached to the end of the gaff, as the peak will not always drop when the wind is pressing the sail against the topping lift. [Illustration: Mainsheet on iron horse.] The foresheets should lead aft and be made fast round cleats or pins within reach of the steersman for convenience when sailing single-handed; the mainsheet should travel on an iron horse across the stern; but care should be taken that the shackle, A, that attaches the block to the horse, should be of a size and shape that will not jam when the block hangs down loosely, and perhaps takes a turn, as it may in going about. One squally day this year, the writer, who had always wondered how people could be so foolish as to get drowned through their mainsheets being foul, found himself, after going about, with the lower block of his mainsheet twisted and jammed under the horse, at such an angle that the sheet would not run: while, to make the mischief complete, the tiller was jammed by the block as well, so that he could neither luff nor ease the sheet. [Illustration: Sail-plan, 'Black Pearl's' cutter.] A jackyard topsail that requires no topmast can be set, and a spinnaker will be found very useful for running in light weather. A bowsprit can also be run out and a jib set; but this will probably be found to upset the balance of sail on the centreboard, and make her carry lee-helm, in which case it will be of no use. If a standing lugsail is preferred, the peak should be cut high, and the long yard should be as light as is consistent with the necessary strength. I can see no advantage over the cutter mainsail, except that the halliards are rather simpler. Old sailors and fishermen will tell you that a boat with a yard is always stiffer than one with a gaff. With a dipping lug, such as fishermen use, or a balance lug, this seems not improbable, as in these rigs a considerable part of the yard and sail is to windward or in front of the mast; but with a standing lugsail, which, if it has a boom, is practically identical in shape with a cutter's mainsail, it is hard to believe that there is much in it--the peak halliards can hardly make much difference.
