Question Where to place the deck limit mark?
Question Details

Where the deck is irregularly shaped near the mast, where is the correct place for the deck limit mark?

Answer

The IOM class rules do not seek to restrict the shape of the deck near the mast. It would be complex to do so and the point to which rig height is measured is taken to be relatively non-critical.


A deck limit mark shall be displayed on the hull centreplane near to the mast position. The mark shall be a minimum of 5 mm in diameter.


It is for the owner to decide where to place the mark.


Once the mark is placed the measurer can carry out his measurements.


Equipment inspectors (event measurers) carrying out pre-race checks may wish to make the deck limit mark 'permanent' by signing over the top.
