Broker's Comments

There are some jobs to do on this boat before she can set sail again but she is an ideal winter project.
She will need to be re-rigged and some stanchion bases will need to be re-seated for starters.

A new sprayhood wouldn't go amiss either.

However she does have a good engine which has only been run for about 30 hours from new and probably cost close to the asking price of the boat!

A lifting keel means she can take the ground and doesn't need the more expensive deep water moorings.

In the same ownership for almost 30 years she is only for sale due to ill health.

These boat details are subject to contract.
Note: Offers on the asking price may be considered.
