On the eve of day one of the challenger semi-finals, we talk again with Cup Experience Founder; Jack Griffin on location in Bermuda about his take on the racing so far in the challenger qualifiers and 'all things' Americas Cup 2017.

We dive into the sailing differences between the teams to date, the surprises we have seen and what we have learned about the importance of 'the start' and the quality of your 'boards' (foils). This 35th edition of the Cup is unfolding into one of the most competitive events ever with close racing, multiple lead changes, collisions, penalties and of course the sailing personalities.

With speeds in excess of 40 knots and teams now foiling up and down wind for 100% of the race, simple mistakes cost you hundreds of metres. This cup is not just about pure boat speed, its also about consistency in execution, winning the start, foil and rudder selection and how you mode your boat for the conditions each day.
