The Iris dinghy
The muse of this project is the Shrike kayak, designed and popularized by Nick and Christopher Crowhurst from CNC Kayaks. Although Iris is not a kayak, her creator hopes she will eventually equal the Shrike in popularity amongst amateur boat builders. Therefore spread the news, enjoy building 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 made constitutions, as ancient kayaking knowledge was used to dimension her. She superficially resembles the Argie 10, and the Walker Bay 10, but the projects have no connection. 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 it full of water).
She sails nicely under a balanced lug sail, but precautions must be taken in a stronger wind, as the sail is cut to respond well in light air.
She can be used as a tender for bigger yachts, but only on sheltered waters.
