vic008 17 Posted December 19, 2015 Share Posted December 19, 2015 Hi think mast is 31ft above deck (written down somewhere). So need a spinnaker and what length would the luff need to be? Thanks. Quote Link to post Share on other sites
B00B00 310 Posted December 20, 2015 Share Posted December 20, 2015 Generally the luff will be about the same as the halyard height from the deck. The foot should be about 1.8 times your spinnaker pole length. Quote Link to post Share on other sites
wal 27 Posted December 20, 2015 Share Posted December 20, 2015 Which should be 'J' + 10%. 'J' being base of the foretriangle so face of mast to forestay pin. Luffs can be 10% longer too Width is pole x 180% (that right BooBoo?) Quote Link to post Share on other sites
