Lee, I'd recommend a halyard restrainer. If you don't install one, the halyard and forestay will be darned near parallel on a cC27.It's been a while since I installed a furler, but IIRC, you need at least 10 degrees deflection between the forestay and haylard to prevent halyard wraps. Read the installation manual carefully -- it has all the details you need to install a furler correctly. It goes into great detail on how to avoid common mistakes.
Also, you should intall a toggle at the top of the forestay with a rigid foil. Otherwise, the lateral forces generated by the foresail are concentrated on the forestay wire at the top of the foil, leading to metal fatigue and potential failure. The toggle at the top articulates, and redirects the lateral forces, protecting the forestay. Here's a picture of Bijou's mast after I rebuilt it. Note the halyard restrainer and the toggle. You can see more pics of the mast at http://www.blumhorst.com/catalina27/mast-repair3.htm Fair winds, Judy B 1977 C27 TR #3459, "Bijou" San Francisco Bay, CA ________________________________ From: Lee Scott <[email protected]> To: [email protected] Sent: Saturday, April 4, 2009 6:17:44 AM Subject: [IC27A] Installing a new roller furler I've just received my new Harken roller furler, and have a couple of questions before I screw it up. First, does the mast need to come down in order to do the initial installation? The instructions say to lay everything out alongside the forestay for measurement purposes, but then later it says that the foil can be installed by sliding it up the stay. But that may just mean after you've reinstalled it. Also, it says that some rigs need a halyard restrainer to prevent halyard wrap. Does the C27 need one? It'd sure be easier to put it on now than have to drop the mast a second time. Lee Scott 1987 C-27 #6350 Shelby, AL
