Main halyard block: jub sizw

[Bob]

Hello....I'm a new Mac-Ven 21 (year 1976) owner, just brought her home today. The wheel in the block at top of mast is broken, I'd like to replace just the wheel because if I replace the hole block, I may have to drill new holes which I don't want to do. If I could replace with the exact block, that'd be fine because I'd drill out the old rivets and rivet in the new one. Where can I buy what I need?On the jib, she came with two, one apox 22x22x12, the other 13'6"x15'6"x7'9". What are these jibs.Any help is appreciatedBob

Bob, I don't believe that you can still find diurect replacement blocks for your older boat. I have an 86 and just replaced the main block on top and spent a good bit of time looking. In retrospect, it was no big deal to install a new Harken ckeek block I picked up at West Marine. I reused the top hole and drilled a new hole to accomodate the new block. It works fine and a lot better than the old deteriorated block.Joe

Try this site for your sail question. It looks like you may have the V-21 genoa and the jib.http://www.wadler.org/Boating/sailsXtype.htm

The V 21

is an interesting rig. Some versions came with a masthead forestay to which the genny is attached, and an inner fractional stay to which the working jib is attached. Check to see if there is a second set of hounds, or an attachment point on the mast and on the deck for the innerstay. Check the brochure at the attached link.I wonder if it is set up to sail as a dual headsail rig in light air.You can purchase replacement sheaves from West, Boat U.S., et.al. But you might like a bearinged block like a Harken better, even if you do have to drill an extra hole...it's only a number 8 or 10, I think.
