Re: Can someone explain roach to me?

John Lecher , author of the self steering book and an aircraft engineer, said without full length battens a roach increases the performance of a mainsail from zero to three percent, but is responsible for 80% of sail repairs.

Do some of those battens go right from the boom to the leech? It looks like the ones in the HR pic does! That must be $1000 worth of battens! And what happens if your furling fails and you have to take the main down the old fashioned way? Battens that long would be pretty awkward. It seems like with the increased risk of the battens fouling inside the mast, and the disturbance the batten pockets cause to flow across the sail the benefit of the little bit of roach it gives you is hardly worth it.
