After a long hard passage back from the Azores we pulled into an anchorage in Plymouth. We tacked and the chainplate of the aft lowers popped out the deck with a big bang!

Ok so the chainplates were now 23 years only and I should have lifted and inspected them before this happened but the aft lowers and babystay had the notoriously bad U-Bolt chainplate arrangements.

You can see the plate was mounted on to of the epoxy/sand deck system. Not ideal as I think water has been able to reach the bolts and cause crevice corrosion.

Back in the 80/90s the after lowers we’re not seen as a primary part of the rig. However, various yachts have lost their mast when the after lowers have parte due to the pumping action of the rig under sail. In fact they are arguably the most important part of the rig!

As such we commissioned David at to come up with an uprated chainplate with 14mm bolts. The flange is welded both horizontally between the bolts and over the top of the counter sunk M14 bolts. This cross weld should be very strong. They also angle the plate to the exact pull of the aft lower rigging.

Note the angle of the flange to maximse strength of equalise pull on the bolts.

When the news ones are ready to be seated the deck will be scratched back to bare GRP. Mountain them on the fake teak deck system was not ideal and I’m surprised it was done in the first place.

I’ll post a photo when it is completed.
