Reply To: Keel Bolt torque settings for a Dufour 455 Grand Large Arpege

    May thanks Andrew.

    What we found out on our keel bolt inspection.

    Torque on 11 accessible 20mm bolts checked. All good. (“Bella” launched Frnace 2006. As far as I can tell this is the first keel bolt torque check. Two previous owners. She was sailed from France to East Coast of Australia by 1st owner 2007 – 2010. Bought by 2nd owner early 2011 and sailed to West Coast Australia over that year. Bought by use late 2021)

    There is a significant distance between the fwd most accessible 20mm bolts, located aft of the mast post, and the 16mm bolt at the fwd end of the keel fwd of the mast post. With the framing of the boat there does not appear to be any access to this area under the mast post to just aft of this 16mm fwd end bolt. Does anybody know if there are any keel bolts in this area?

    FYI. There are two 16mm bolts at either end of the keel, the fwd one is inaccessible to a torque wrench being under the fwd heads shell.
