From the above the big advantage of twin self-launching poles seems to be stability in a blowy gybe but the majority verdict so far seems to be for a simple conventional single pole with elasticated downhaul with positive stop and adjustable twinning line – which is what we’ve been using up until now.
We use a single twinning line (from port side to starboard side via a loop back to a single adjuster at the helmsmans position to remove length and avoid some of the skying during a strong wind gybe). Spi sheet and guy pass through lightweight plastic rings on the end of the twinning line and are renewed each year.
But keep the opinions coming – thanks so far.
