I have an Aeroluffspar and have been very pleased with it. It rolls very neatly and when not furled it has a nice fine entry which means the genoa doesn’t lose any power. Another big advantage is its flexibility which allows for easier transport.
Any pictures Matt? Their website doesn’t show any details.
Our Helyar MK2 performed well during a week’s daysailing on the Western Solent, but when used in 30mph winds for a club handicap race we couldn’t get enough rig tension due to the longer length of the luff/furler combination – this is a setup issue rather than a design flaw!
