Heeling to that degree is not a viable option on an ongoing basis.
You mention the big blue sea, might you have a tide, that could range up to 8'+ in your neck of woods. Bridge clearance is published
based on mean high water...so if assumptions above are close you
may have about half time that you clear...??
If close remove vane, but I would bribe a buddy with a dinghy/powerboat and check out first with a few 10' lenghts of pvc.
