FAQ
CAN I BUY SPARE PARTS FOR SEVERNE BOOM HEADS?
Yes. These are available for order at your local Severne dealer and different online Severne shops. Use the dealer locator to find your nearest dealer/distributor.

METAL 160-210 – 2.85kg
METAL 170-220 – 2.95kg
WILL THE BOOM BE LONG ENOUGH FOR MY SAIL?
This depends on your sail dimensions. You can of course sail with the boom fully extended, but we recommend keeping an 8 – 10 cm buffer of the maximum extension of the boom.
HOW CAN I RIG ON AN RDM MAST IF THE BOOM IS SDM?
Severne LockJaw SDM boom heads are compatible with RDM masts. Simply tighten the rope more to adjust for the slimmer diameter of the RDM mast.
HOW CAN I RIG AN SDM MAST IF THE BOOM IS RDM?
Severne booms with RDM LockJaw boom heads will not fit onto SDM masts. Metal 140-190 and Metal 150-200 use RDM boom heads.
HOW DO I REPLACE MY BOOMHEAD?
Contact your nearest Severne dealer for assistance. Use the dealer locator to find your nearest dealer/distributor.
