Why to hoist the main first and drop it last
There are too many interesting issues raised in this thread and too little time to respond to them all. Let's just tackle this one issue now.To understand why you should normally raise and drop the headsail (genoa, jib, staysail) first, imagine you are flying both mainsail and headsail and have decided to head up and drop the main first. Even with both sails tightly sheeted in the headsail will start to luff -- and then flog -- before the main is luffing enough to let it drop freely. So, the whole time you are trying to deal with the main the headsail is trying to self-destruct, while making the foredeck unsafe (clew flying around) and distracting everyone on board from the task at hand. Therefore it is generally advisable to drop the headsail first.When setting sail, there is an additional reason to hoist the main first. Typically, one motors into the wind to hoist sail and then reduces motoring speed as far as possible to avoid unnecessary windage and slamming into the waves, while keeping just enough speed on to avoid getting stopped by the waves and lose control of the bow (remember; the rudder only works as long as it keeps moving through the water.....). In this situation, setting the headsail first would add to the tendency of the bow to blow off, thus requiring more speed and creating unnecessary windage while hoisting the main (aside from the fact that the headsail would be flogging again throughout the entire procedure).If, for whatever reason (e.g. your engine won't start and/or the headsail roller furling tends to jam), you want to drop or hoist the main while leaving the headsail up there are a few tricks to reduce its flogging tendency.The easiest method is to head up till the tightly sheeted headsail starts luffing slightly, then keep that course and move the boom to leeward till it points straight into the apparent wind direction. Don't forget to use the traveler or a preventer to prevent the boom from slamming back and forth (particularly if you need to leave the cockpit to flake or tie down the sail). Now you should be able to raise or drop the mainsail. Note that this is the same trick of bringing only the boom into the wind-- rather than the entire vessel -- also used in some of the "easy" reefing procedures discussed in an earlier thread.Throughout all of this it is important to sheet the jib as far as possible inboard. This is easiest if you happen to have a staysail with a high cut foot. On Rivendel II we can sheet the clew of the staysail anywhere between port and starboard, including amidships, by using both sheets. If you have a full-sized furling jib you may be able to furl it 20-30% and then sheet it inboard the same way, i.e. by putting tension on the lazy (windward) sheet.If none of this is possible you can try to attach a temporary third sheet to the jib clew and run it to one of the winches via an inboard snatchblock, provided the leech clears the lower spreaders (with B&R rigs this will usually be true for genoas that are 110 % or less).Have fun!Flying Dutchman
