With the optional 55 SF sail you'll go faster.

This sailor is using our "High Seat" option that sits on top of the gunwales, so he can easily sit on the windward gunwale, to counterbalance the force of the big sail in a strong wind.  

The heavy-duty mast is require with the larger sail.   It's stronger and the height is adjustable -- up for more headroom, down for less heeling in strong winds.  With the nylon 55 SF sail (as shown) the heavy duty mast upgrade is included.  See item 5011.
