The Iris dinghy

The muse of this project is the Shrike kayak, designed and popularized by Nick and Christopher Crowhurst from CNC Kayaks. Despite the fact Iris is not a kayak, her creator hopes she will equal the Shrike in popularity amongst the amateur boat builders one day. Therefore spread the news, enjoy the build, enjoy the boat and keep the tradition going.

Iris is designed to carry one adult and one child under sail and 3 to 4 lightly built adults when rowing. Her frame is wrapped around lightly built constitutions in fact, as ancient kayaking knowledge was used to dimension her (why creating a bulky boat with a lot of space needing a lot of materials when we’re small and can fit in a smaller boat with room to spare even). She superficially resembles the Argie 10 and the Walker Bay 10, but there is no connection between the projects. Iris was made to be Daddy’s boat and to teach sailing to the kids: a nicer looking Optimist or a Mirror on steroids.

She can be built from cheap materials more or less by anyone.

The boat is easy to row empty or fully loaded, stable enough to stand up in it and, due to the closed spaces within the hull, she is virtually unsinkable (but this doesn’t mean it is comfortable to have her full of water).

She sails nicely under a balanced lug sail, but precautions need to be taken in a stronger wind, as the sail is cut to respond well in very light air.

She can be used as a tender for bigger yachts, but only on sheltered waters.
