N ick- if you stagger the exit holes at the bottom it'll be fine. Yes, just drill down thru the base of the masthead, in line with the sheaves, of course, and the best way to run the lines down is all in a bundle so they won't twist (maybe). Regarding the exit holes, I drill them with a 3/8 bit (for 1/4" halyards you could use 5/16), then take a long rod, stick the rod in the hole, and bend it down so that the halyard leads down to the deck block cleanly. It's stronger and easier than making a slot, but maybe not as pretty. For the spin halyard and topping lift, which will first go thru a swivel block, make the mast entrance a few inches below the block, and bend the hole up for less friction. I;d use 5/16 line for the jib yalyard (one less turn on the winch, and less stretch) and 1/4 for everything else. A hint is to lay all the lines out, tape them together, and mark the bottoms with a series of dots with a marker pen, each a different color so you can snag them with a bent nail and pull tjhem thry the proper hole. If you n eed an electrical wire going up the mast, safest way is to glue up ABS pipe and run the wire thru it. Internal jhalyards are great and if done sensibly won't snag and will gain you a couple of boat lengths on the way to the weather mark. One of the things that, when you add them up, make a significant difference in speed. jerry ----- Original Message ----- From: "Nick Chappell" <hnchappe@yahoo.com> To: <montgomery_boats@mailman.xmission.com> Sent: Tuesday, April 12, 2011 3:11 PM Subject: M_Boats: rigging internal halyards
Hi, all --
I have been lurking on the list and tinkering away on upgrades and fixes on my M-17. Thanks for all the good advice and info!
I want to convert to rope halyards and have modified the sheaves of my old (1975) masthead to accommodate 1/4-inch line. The sharp bend at the masthead to get the line on the sheave is too much friction, so I am planning to rig internal halyards. Anyone done that? How best to proceed: one or more holes in the masthead base? There could be 4 lines (3 halyards and a topping lift) -- is that asking for trouble?
Any advice or shared experience will be much appreciated!
Nick C. M-17 #69 (one of them)
