I need to replace my jib halyard exit block. The block that fits into the mast for the 8mm jib halyard line. Does anyone know where to find a new one?
That’s interesting, my F21 has an external jib block and only the spinnaker and main halliards are internal to the mast.
I am not sure what kit was used in your mast but if you measure it up and search any chandlery for exit blocks you can compare sizes. You may need to go to the manufacturers to get full specifications.
Good luck with your search.
Ya, I only have one fore halyard so it may have been for the spinnaker. My boat is a 1987 vintage. Looks like some kind of plastic pulley and a stainless steel housing. I checked harken and schaefer but couldn’t find anything. You don’t know which manufacturer may have fabricated this block?
One option is Rig-Rite.
Usually pretty good at helping with mast parts.
Yes that is the spinnaker block and its exactly the same as the one I have. It is an unusual fitting, exit blocks usually have attachments either above and below or to the sides on flanges that sit against the mast but ours is recessed on that pair stainless straps.
What exactly is the problem with the block? It might be possible to just replace the sheave if you remove it.
I would be interested to see more if you do decide to remove the block to investigate further. It may be a standard block with a custom strap fixing to recess the block.
I attach a pic of mine, you can see the job block mounted just below the spinnaker block, externally. Sorry for the poor quality its a blow up of the whole boat.
The sheave is missing. I believe the rest of the block is intact. Here’s a closeup of it. I’ll send you another pic when I take it off. Thanks for your ideas.
It’s a harken through deck block. Double check the size, but if my notes are correct it should be this,

you don’t use the black plastic trim piece. You need to drill out the rivets on the stainless steel strap so you can move them out of the way to take out the block You’ll need these rivets.

It’s a pretty easy job to do. I replaced mine about 10 years ago.
Thank you for your info.
Has anyone installed a second block like that above or below for the second halyard? I don’t really want to do an external block but I don’t know how much another big hole would weaken the mast.
Also, @pburos I was looking through your profile to see if you had any pics of your F21 - are you still in Sarasota? I’m not far away in St Pete and I’ve never seen another F21 in person - I’d love to get together and sail sometime / check out your boat.
Ian, I’m guessing that elongating the hole at the same location for an internal jib halliard would severely weaken the mast. I’m pretty sure the SS fittings on the Spinnaker block are there to reinforce the mast around the cutout. With smaller diameter HMWPE lines you might fit a smaller double block in the same cutout.
Dear Ian
Sorry I didn’t see your request until now.
As to your first question, yes I would think a second internal halyard could be installed w/o too much trouble when the mast is down. Would need to buy the exit block, the ss halyard entry fitting at the base of the mast, and cut out holes in the mast. We have a F21 in our fleet which has two fore halyards. Don’t know whether it is a factory option or done after.
We have pics of three F-21s, including my Sweet Caroline, in our fleet in Sarasota. Go to pelicancovesc.com and click on pics. My e-mail is pburos@gmail.com. I would welcome you coming down to Sarasota some time.
Thanks! I might try that one day after I finish the million projects I have in progress. It would be a huge improvement.
And that’s awesome! I had no idea there were so many F21s in the area - I thought I was alone. Looks like you’re about a day’s sail from me. Maybe one day I’ll take the trip down there and race with your fleet.
Dear Ian
We would welcome you coming down. The fleet is in Pelican Cove. We should be able to arrange an overnight transient slip for you. Our next series starts Nov. 29-Mon, Tues, Thurs, Fri. for two weeks. Let me knw.
Sorry to revive an ancient thread, but can anyone confirm that this is definitely the Harken big bullet block and not the regular bullet block? I need to do the same repair and frustratingly forgot to measure the dimensions when I had the mast down (that’s what I get for hurrying…).
Also, do the rivets on the block itself go all the way into the mast or do they just go through that steel strap?
I’m thinking about upgrading to a Harken 1202 40mm Protexit block. Much more expensive but more than 2x the breaking load feels worth it.
