J/30 Class Association Forums J/30 Forum The Boat, Sails and Equipment Changing mast foot blocks

Marie,

Your English is much better than my French so no worries!

You should not attach halyard turning blocks to the deck as it is not designed to withstand the loads from the halyards. Riveting the blocks to the mast is the proper location.

If you go to the menu at the top of the forum, mouse over "Market", then click on "Equipment Suppliers". This will provide a listing with links for many suppliers where you can get replacement parts. The supplier you want for replacement blocks is Rig-Rite Inc. Here is a direct link to the Rig-Rite page. The entire Halyard Turning Block Assembly part number K-10865 is shown below. Perhaps you can contact Rig-Rite to see if they will sell just the Sheaves so you don't need to replace the entire turning block.



Edit: I found the replacement sheaves on this page. Part number K-10861-B5
