Crownline's 21 SS has the same sleek style of former generations, but is slightly rewritten to include additional attributes that make for a first class boat. The 21 SS offers a convenient walk-thru transom and a fully integrated extended swim platform. For handling ease, it features Crownline's state of the art F.A.S.T.-Tab hull design. The bow rails, shocks on sundeck and lids, cupholders and grab handles are all stainless steel. Its digital depth sounder displays outside air and water temperature.
