Dual sheeve ....

Made for the old fashioned rope to wire spliced halyards. Wire cable rides in the smaller groove and the rope portion rides in the wider part. Modern high tech non stretch lines/rope made the wire-rope combo obsolete.

No disagreement with Rich here

They look like they are for wire rope but wire and rope may be obsolescent but not obsolete. They are still supplied by most suppliers and I still use them. Joe S

Not obsolete... I agree

Wire/rope halyards are commonly available at most any chandlery. They are desirable where space is limited, such as the narrow masthead sheaves on Catalina 27's and the owner doesn't want to spend big bucks on high tech line. I think obsolete is the incorrect term, if you'll pardon me RichH, perhaps "uncommon on newer boats" or "less popular these days" might be a better description.

Wire to Rope Halyards

No, Rich is correct. The definition of obsolete fits. Just because you guys still love them doesn't make them not obsolete. I would have changed to all rope years ago (none of my boats ever had them), but I have never owned a boat that old. Still Jaded

They will work but...

Your halyards will wear quicker.

Mast head sheeves are easy to replace ....

Tim states correctly that with soley rope halyards, the rope will wear faster with the combo sheeves. Not a big deal if you keep an eye on the rope and trim back when necessary.

Tim...

You need to get your boat back together... ASAP! They are picking your boat up in a month. Your cover is still on you know!

Bear hooks?

I have them on my H27, but my hands never touch them. I worry about the splice though...

Quit nagging me already Rich :)!!!

I feel guilty enough about going away with my family this weekend without working on the boat. I did take Monday off though and will spend all day installing bungs. I think there are about 100. I may also install 6 of the 10 new portlights.

Tim 100 bungs shouldn't take all day. If the counterbore

is there and the bungs are cut, one minute each in place and trimed with a sharp chisel is all you need.

I beg to differ Ross

Bungs don't chisel off square, even with the best chisel. So you have to chisel them high to see the run of the grain and then possibly come from a different angle to finish. The other issue is that they are not all neatly laid out in front of me. They are all over the cabin, some in very hard to reach areas and at very difficult angles.

I chisel bungs off about a sixteenth at a time. The chisel must be sharp enough

to shave hair of your arm and it is best if you cut your own from the straightest grain wood you can find. I have done a few thousand I am sure. Neat cabinet work demands them.

As stated, they'll work, but not the most desireable choice. If you can get that close to get that clear a photo, then changing out to new all rope sheaves shouldn't take more than a few minutes, and they aren't expensive. Go with the new sheaves.

meathooks

By bearhooks I guess you are talking about the broken strands on the wire halyards that stick out and grab you. We call them meathooks for obvious reasons. Ray T
