  For Sobstad/Dolphin/Northrop Round Head sails, the battens are as above except for top batten, which is   900mm.   (Seven inner & outer caps are required)

 John Pep notes:  The Hyde sail comes without battens. Hyde "contract" battens   are non tapered, and suitable for cruising but they not enough  for racing.
  It is about deform loads and max camber position. The Catapult sail needs battens that deform with load of 3-3.5lb max. With non-tapered battens, the 3 lower (longest) battens deform at 2-2.5lb (too soft) while the top 4 battens deform at between 5-10lb (too stiff).
  Contract battens have their max camber at 50% of batten length, whereas taper battens have the max camber forward at 40%.  For this reason, alternative battens as above are needed.)
