Barefoot International V-Drive Boom The Barefoot International Deluxe V-Drive Boom fits all v-drive boats with 2 1/2" diameter ski pylons. It features a larger bend than any other BI boom to help position the boom closer to the center of the boat. Like all Barefoot International booms it comes with a beefy two bolt pylon clamp and quick connect pin. Double cables add extra safety and ensure a solid pull. If you will be using this for barefooting we strongly suggest adding a boom extension to get out of the spray. IMPORTANT: Make sure you have at least 3" of non-tapered pylon exposed to safely mount the clamp.
