It is easy to have end boom reefing lines stay on the same side of the main, it' all in how you lead them thru sail & back down. Thoughts? Is there a book I should read on this? I suppose I'm overthinking this and should just trust my sailmaker, but moving a poorly chosen reef is no small thing. Having the clew reef point higher 6-12" up from the boom would, as with the tack reef point, would allow for some control in direction of lead by tightening or slackening the clew reef line Planning the placement of the clew reef point to allow a slightly higher tack angle could keep the boom modestly up higher and that much further from the water on a reach. How high should the tack and clew cringles be, ideally, relative to the boom? Should the boom height change? As a thought experiment it seems like keeping the tack cringle 6-12" up, and 3-6" aft of the luff, would get the cringle out of some of the clutter by the gooseneck and allow a little less precision in placement of blocks/fairleads/eyes.At the opposite end of the spectrum some boats have T-track on the side of the boom and a car for the clew reefing block and eye. This results in good (excessive?) luff tension but little horizontal tension between the tack and clew, along the line of the imaginary "foot" of the reefed sail. How important is the direction of lead? I've seen many boats where the clew reefing line runs over a sheave at the end of the boom, through the cringle, and then is tied around the boom.There's less friction, and it keeps both the working and dead ends of the line on the same side of the sail without chafing the leech. At the clew, some sources suggest using a block on the sail - either a specialized one permanently attached to the sail with sewn webbing in place of the grommet (Bainbridge and Antal make them), or an ordinary non-swivel block lashed to a ring or toggle on the other side of the grommet.I am planning on two-line reefing with control lines run to the cockpit. Want to get this right especially if I get a new sail early after purchasing a new boat, rather than making piecemeal changes. I have several questions about how reefing lines should be rigged on a ~38' boat.
