Comparision between the old and new marstrom.

Hull:
Full length in the waterline.
Reduced rocker.
Minor changes on the distribution of volume.
Integraded fittings for shroud and forestay.

Foils:
New centerboards with reduced width

Beams:
New mainbeam without dolphin striker.

Manufacturing
Shroud and forestay fittings are integraded in the hull and no bulkheads. This means that there is no need to cut a hole in the deck to do that installation when the hull gets out from the autoclave. Just put the stern in place and add some paint!

By the way, the A-class spi snail is finally ready, it took a while....
I will post pictures when the first snail is painted and ready.
