Hi,

I think you should steam bend. There's nothing wrong with laminating, you don't need lots of forms, just a board, some dowels (or machine screws) and a drill to outline the corner points of your curve and clamp the rib layers to it while drying. You also don't worry too much about the backspring, this can easily be bent into final place as long as the curve is not too far off the design (5 - 10mm).

My main point in laminated ribs is that the compound of wood/epoxy is stronger than the sole wood. If your hull is impacted later on, a strong rib will make the horizontal stringer break, whereas a rib of similar mechanical properties as the stringer will move together with the stringer.

Kind regards
Mike
