Hi Sigma 33 enthusiasts, I considering to buy a Sigma 33. During the first look it turned out, that the keel bolts have been changed about 6 years ago, but not the two most forward once. Therefore I would like to place a question about changing these particular keel bolts (blow the head compartment). Has somebody a rough idea about the effort to change the forward two keel bolts? These two bolts in the head area are looking quite rusty.
Greetings Amalphi.
