The ideal boom for these goosenecks is a simple piece of 14 mm carbon tube requiring no special bonding to fit the gooseneck unit. If necessary to prevent the boom from rotating under load it can be locked in place using a small self-tapping screw.

Mast ram insert, item 140-M3, provides for inserting a M3 nut where required for the type of mast ram used on NIOUTRAM - may be useful on other boats.
