Re: Mast sheeves sticking
There's no point to splicing lines for a halyard in a boat that size. The current halyard will probably last 15 more years. A Ranger 23 (according to the OP's profile) has got to be at least 20 years old, and the sheaves probably need replacing, or at least new bushings to help them roll properly. Get her over by a pier at low tide and tilt the mast over to have a look. You may find that the sheaves have essentially disintigrated, and you're hoisting over the pin that they're supposed to turn on, turning it into a misshapen pretzel. When you do this, be sure to have something to measure the pin and sheaves with (so you know what you'll need to get to replace them, if necessary) and a can of lubricant (that you can use if things just need a shot to get them going again). Sometimes halyards can jump the sheave, too, and simply putting them back in place will work wonders.
