Great dingy. Congratulations.
Have been an admirer of the concept
of a small cat dingy for a long time.
First saw the concept
with a M&M design dingy built for a M&M 50ft cruising cat built in NZ some 12 years ago by an American couple that are now based in Tasmania.
There are quite a few home builders with there own designs but the Spirited Kit/Plans available in Australia
in Foam/balsa/ply are similar in concept/weight to Cotemar's dingy.
Using such plans one could resin infuse flat sheets
of foam oneself or have someone do it to be cut into parts
for assembly if not in Aus or if in Aus buy the kits for assembly.

Quite a few building Schonnings catamarans have built cat dingys as a learning
curve to building the larger vessel.
Not having tested a spirited design dingy myself but looks suggest similarities in operation. There are 3 x 4.2's that have been built in Hervey Bay in an article as day boats according to latest Australian Multihull
Anyone in or travelling through Hervey Bay In Aus that can check them out?? --- 44C perhaps !!
