I recently bought a '99 170. I've noticed from viewing other owners 170's pics on this site that their mast carrier is noticeably larger than the "short & stubby" one I appear to have. It appears Hunter revamped the original (which I must have) to a taller version that includes a hole for the boom as well. Biggest problem I can tell from trailering only once thus far with the smaller version, is that the spreaders scratch the cockpit while in transit. Anyone familiar with when Hunter made this adjustment & where you can recommend purchasing a beefier mast carrier that prevents the spreaders from touching the cockpit? Thanks,
