We put two 7-hole adjusters on my son's 14 and that wasn't enough!! But we were also limited by longer (read older) shrouds and had them in the bottom hole. A new set of standing rigging will get you on your way, but do you have low-profile blocks? Lots of rake, like the H16, is the way to go.

All that "extra" line is typically the remainder of the main halyard, cleated off and then looped around the crossbar to main cleat.

Foot on the boom to keep the sail out as far as possible. Sail the 14 damn near DDW (dead down wind), sailing a higher course and gybing (ala Hobie 16) is not the fastest way from the windward to leeward mark.
