5-3/4" Hide-A-Helm Steering Wheel Adapter

If you've been fortunate enough to see inside some of the most elite powerboats in the world toady such as Nor-Tec and Outerlimits, then you've probably noticed the ultra-cool dual switachble hidden helms they have.  Hardin Marine developed this system with two thoughts in mind.  First, dual helm steering systems up to now used two mounted steering posts fixed to both sides of the dash.  When one wasn't being used it stuck out of the dash as a safety hazard similar to a human harpoon.  By relocating the steering post beneath the surface of the dash and covering it with a smooth billet cap you now have a part that is worthy of existence on a million dollar boat.  Secondly, the easy removal of the steering wheel allows it to be stowed and locked beneath the cabin.  No steering wheel, means less chance of your boat being stolen.
