G'day,
Following is in reply to a question from Robert about the new rudders. Attempts to reply to his email address have failed.
G'day,
Should be some pictures on the next web update. Version one broke, version
2 is being built by the Belgians.
They steer the boat well, according to Mark who was test pilot. Not
surprising, as the hull mounted ones are more than adequate, and I reckon I
could steer with the sails alone if required.
Loads on shafts are higher, but these are easy to beef up. Loads on
bearings are also higher (only 300mm apart), but again, easy to beef up, and
because it is all on the beam, the additional laminate is not much more
area, so weight stays low. Far less likely to get damaged than the hanging
off the side variety. Mark 1 was removable, mk 2 will be fixed to the beam,
making strength less of an issue.
Regards,
Rob
