Furler query

In regard to your review of top-down spinnaker furlers (PS, January 2014): What about long time storage of the spinnaker wrapped around the torsion rope? Will the tight wraps damage the sail eventually? Also, as the tension of the halyard goes all in the tension rope, there does not seem to be a luff trim option.

Unlike standard genoa furlers, top-down spinnaker furlers are not intended to be left hoisted with the sail on for long periods when they are not in use. When it is to be stowed, the sail should be furled and lowered. Leaving the furled sail in a bag/turtle and stowed below doesnít harm it at all. As far as the luff is concerned, the only direct connection of the sail and the torque rope is at the head swivel. The sailís tack is attached via a snap shackle or shackle to the furler drum or tack line, which can be used to tension the luff. See the accompanying illustration, which shows how a Ronstan top-down furler works. For more on top-down furlers, check out Part 1 and Part 2 of our test report in the January 2014 issue and in this issue.

Can the author of the above article on the H2out filter provide me with a little more detail. It looks like he has a poppet check valve, exactly what one? Plus I noticed on the article in the January edition that their is a valve or another connection on the same line as the filter. I have tried to find more information on check valves but there are so many and this me in the letter above is a three way valve. Love to have the detail!
