Inspecting Your Mast and Rigging

Mast and Rigging inspection

Your sailboat rigging should be thoroughly checked once a season. The best way to do this is by pulling the mast or masts out of the boat and running down a check list. One can also spot most major problems from a bosun’s chair, and if done regularly, is generally more cost effective. It is strongly recommended that you have the spars pulled at least once every 5 years depending on the conditions that your boat and its rigging have been subjected to.

To help you do your own rigging check, here are some general guidelines for the average sloop rigged boat. For any specific questions or concerns, please don’t hesitate to call.                                                                                                                                                

A.    DECK LEVEL AND BELOW DECKS

Deck Level inspection

1. Check the boom gooseneck for worn pins, cracked welds, etc.…

2. Check the boom for bends or dents.

3. Check all block attachment points on the boom for fatigue or wear, i.e. vang bails, sheet bails.

4. Check all blocks and shackle attachment points for bent pins, distorted shackles, missing or loose ring pins, etc.…

5. To check halyards, attach a spare line (or the bitter end of the same line) to the shackle end and pull up on the halyard slowly. Check the line and check the shackle for proper operation.

6. Check all shroud, stay, and lifeline swages for cracks.
