Time to rerig the boat. The running and standing rigging
are both mostly original 1984 so guess it is about time. In the process wanted to see if it was possible to install a spare halyard
for that just in case situation. I have had a halyard
shackle let go at sea when going up the mast
to retrieve it was not an option.
setup has two external halyards, one main, one jib
. The masthead has two side by side pairs of sheaves, front and back sides of the mast
. The main halyard comes up the front of the mast, over the front sheave, inside across the top of the mast over the aft sheave and down the back of the mast. Jib
halyard rigged the same way just in the opposite direction.
No way to add another halyard in this way without major modification to the mast and sheave arrangement. However, looking at the setup I thought it might be possible to take a halyard over a sheave and down the inside of the mast instead of across and down the other side. Then I could potentially have four halyards, two front and two back.
First question, any reason why this would be a bad idea?
Second question, how do I get the halyard back out of the mast at the bottom? Last boat I owned had internal halyards but a deck
stepped mast. It had matching sheaves top and bottom of the mast so the halyards exited around the sheave at the bottom and up to the mast winches. Since this mast is keel
stepped that is not an option.
So far I have two ideas.
One, cut a small, tapered, exit slot in the mast above the winches. Line the slot with a smooth, angled stainless fairlead to reduce friction and chaffing.
Two, install sheaves inside the mast, under the winches similar the the setup at the masthead with a slot next to the sheave for the line to exit.
Both ideas would require making fairly large holes in the mast, rough guess maybe 3/4" X 3-5" for each opening so total three or four new holes in the mast. First concern is how much this would weaken the mast. Also, as I think about it, the project
may end up requiring a lot more planning, time, cost and effort than it's worth but having a spare halyard would be nice.
I have a few more dumb ideas for the re-rig but will save those for another post and additional entertainment value for the forum.
