Single Yacht Lifting Point

30 September 2008

The old lifting point, using two stainless steel wing bolts, was not secure enough and needed a more permanent solution. The rear keel bolt took most of the strain but only half the thread, of the ring bolt, was covered by the too short bolt.

A stainless steel plate and lifting point was fabricated to cover the rear three keel bolts. Although this is an expensive solution, we could never be sure when we might get a pen in the water and so may have to be on hard-stand for a while. This makes a secure lifting point important to be able to access the water easily and rapidly by simple crane rather than travel lift.

To obtain access to the subsequent lifting point we had to cut a hole in the roof of the cabin and through the garage roof as well and these will be subsequently covered by access screw-in ports. With a new three ton ISO lifting strap and two Spectra strops to the back of the boat we get a nice flat lift and crane access will now be easy and safe for yacht and people.
