There are things you should know from the standpoint of a dealer who introduced and sold nearly 1/4 of the of the Hunter 260's.
First with any boat, you cannot sail direct into the wind and there are some over the years who said I was wrong. Generally 15 degrees off point of wind is as far I would go into the wind. This of course was a water ballast boat designed for trailering. The hull itself is flatter than most other boats; therefore, I suggested never heeling over 12-14 degrees controlling the boat by sail inventory. It is best the jib which is a 110 should have a furling system. The main since there is no backstay was designed to be bigger than standard as the thought the power should be in the main. That said, the total area of the 110 jib and the main equaled to that of a standard main and a 135-140 genoa. Usually when the winds are in excess of 14 knots or more, I suggested reefing and practice. If for example the winds are blowing heavily say 19 knots, reef the main when going out and then the furling jib. You can always add a second mainsail reef if you want to sail in 20 plus knots but folks with you might not be comfortable so think of others who are with you.
Never sail direct into waves but rather at angles. You can raise the centerboard going downwind but at any other point of sail, leave the centerboard down. There will be disagreement from others, but the above information is based on experience and knowledge.
As for travelers, I never felt one was necessary and thus never suggested them. With practice and time you will learn. Sails that are old can as Rgranger said, can affect some performance. As for installation of any travelers say attachment to the back seat rest in the cockpit wall, forget about it. Access is hard plus there is positive foam floatation in that area. The ceiling liner in the cabin particularly in the rear berth is a liner only and not structural. Therefore, never secure the bolts holding down the traveler via the ceiling liner as it is not structural. You will need to cut a 2 inch holes in the liner to access the underneath of the protruding bolts to secure under the deck itself. As for the holes in the ceiling liner, you can purchase plastic caps either in white, black or beige at Ace or Home Depot. Probably at Lowes as well. That will cover the holes with a cover but suggest buying the caps first so you know what to cut in the ceiling as they come in various sizes.
