The BG Race shipyard, founded in 2013, built many designs for Archambault and went out of business in 2017.

[1][2][8][9][10] The Grand Surprise is a racing keelboat, built predominantly of fibreglass.

The hull has a plumb stem, an open reverse transom, an internally mounted spade-type rudder controlled by a tiller and a fixed swept fin keel.

The galley is located on the port side just aft of the bow cabin.

A navigation station is opposite the galley, on the starboard side.
