I spoke to Dave Wade yesterday about the twin pole system . He thought it would work well on a Wayfarer .
However the singular reference to ‘ pole ‘ in the rules is an impediment and the requirement that the pole must be metal or wood ( not carbon ) would make the system heavier .
Off the top of his head Dave thought a system with metal poles would cost about £1200 some £300 less than using carbon poles . End of subject I suggest !
