For the beach version, if it gets that far, there would likely be a light wind/heavy boat sail and smaller, heavier sail for heavy wind/light boat. Select sail based on weight of crew and wind conditions.
The nomenclature I am using for the rig describes the booms poling out from the mast. In the model we have a compression beam across the foot of the sail and that is what we plan to do with the beach version as well. That beam across the foot could be part of a roller furling system.
The revised rig has non-rigid boom vang and that can be released to depower the sail. This is an alternate to releasing a sheet from the foot to depower, which would not be possible with the foot on a furler. When the vang is released the sail lifts and projected area in the vertical plane reduces while horizontal projected area increases - some risk of lifting off the water if gust is strong enough but the boat would loose apparent windspeed due to rapid increase in leeway once the rudders let go.

Have you thought about having a roller furling boom? Or do you need to have the freedom to slack either tack of the sail for depowering
