Harken/CDI
I'm no expert, sailing my H23 on inland waters. She has a CDI furler. Last week we chartered a C&C 30 in the Apolstles that had a Harkin. The Harkin with a 145% jib on a masthead rig, 30' boat in 35 knots of wind worked better than the CDI with a working jib on our fractional rig 23' boat in 15 knots.The difference manifested in two areas; the Harken was much easier to furl in spite of the increase size and winds and the harken kept a good sail shape when furled from 145% to 90%. Some of that, I suspect, is in the quality of the sail.I thought the CDI is OK but not good in heavy weather.
