Are you talking about a sail that is pinned to the boom at the clew separately from the mainsheet? If you put a strop around the boom and use that connect the mainsheet directly to the sail and only use the boom for outhaul, you shouldn't be able to bend the boom (I wouldn't think).

On the Nacra 20s I've owned, it was amazing how much we could bend that rectangular boom when sheeted hard (because the sail and the sheets were pinned at different places).
