1)
As the male part of this rod terminal type/size is too large to pass through the luff extrusions, the
rod forestay can only be cold-headed at its upper terminal end after the stay has been pulled through
the assembled extrusions. The extrusion must be made 200 mm (8”) shorter than the stay at the top
to make room for the cold-heading machine. Consequently the luff extrusions length and available
sail space is reduced. The system has to be manufactured by the rod manufacturer, which may give
rise to transportation problems.
2)
The upper eye terminal must be of the MNY type.
