• Sailing Videos:    

                                     Here's a TIP.  To fully appreciate these videos and the ability of the W17, view them on a                               screen in the 20-30" range.    Connect a HDMI cable from your computer to a small TV screen                                       and select the HDMI mode on your TV Remote.    The result is really worth the effort ;)
