Produced by Trident-UK from around 2002. Constructed using foam sandwich (Foam Reinforced Plastic (FRP) = thin GRP skin, then foam, then another GRP skin). Identical deck layout to most wooden Mirrors (i.e. Mk2 interior) with a gunwale moulding to give inner gunwales, bow shapes and quarter knees. The deck mould stops at deck level.

From 2002 until 2007, this was the only game in town if you wanted GRP, so quite a few made and the "Mirror Race" version was pretty well down to weight, stiff and on the pace with the best wooden boats. Dave Gebhard won the 2002 & 2004 European Championships in one of these boats.

In 2006 the International Mirror Class Association asked Phil Morrison to restyle the interior of the Mirror dinghy for GRP construction. The result is known as a Mk 3 interior which has no cuddies, dished decks, curved bulkheads, a raised platform for the mast step, and wrap over gunwales. The requirement for a hole in the skeg was also removed so the skeg could be formed as part of the hull mould. The result is a boat which can made from just 3 moulds - hull, deck and thwart/daggerboard case top.
