Artemis is designed by Axel Schmid as a fast but comfortable sailing canoe. Compared to a canoe that is used only for paddling the hull has more rocker. This means it is more rounded lengthwise. The small skeg helps to track straight while paddling. The flat bottom aft helps for planing.
The hull is relatively narrow, at 77 centimeters, and is 4 meters 85 long. The weight is well under 30 kilos for the boat including floatation and seat, and while travelling the total weight including the full rig, luggage, water, food and fuel is under 70 kilos.
The boat is a true 50/50 sailing canoe, meant to paddle just as well as it can sail. My top speed while paddling is 4 knots, under sail it was 12 knots. But, to be fair, on an average camping trip my daily average is about 2.5 knot. Typically, I make days between 20 and 50 kilometers.

Hull
The leeboard is cut to size from a Marstrom catamaran. The rudder was used on a F18 catamaran. I wanted these to have a near perfect shape, so have not made them myself.
An automatic release cleat keeps the leeboard down. But lets it come up in shallow water.
The small dodger is cut from an old mainsail.

Sail
The lugsail allows to quickly douse the sail and rig. For example, this helps to go under a low bridge.
I have put a third reef in, which allows me to sail in winds over at over 25 knots. The reefs go in via a loop at the front of the boom, and also there is a loop at the back of the boom. This goes into the shackle. A dogbone is pulled through the aft end of the sail.
When you are reefed, this system allows to still tighten or make the sail fuller by using the outhaul.
My mast is a stiff windsurf mast. I cut off the lowest metre, sawed it in half lengthwise and stuck it back on the new lowest metre.
Because windsurf masts are most flexible at the bottom, this ensures the mast is stiff enough.
Masts of lugsails should not bend, only the yard should have a little flexibility.
The plank is only used it in flat water and with a stable wind. It helps to increase stability and give more power. When you tack you shift it and fix it on the other side.
The boat has 4 modes of going forward. Sailing,
paddle sailing with a single blade paddle, when I do that I sit on this bench and I take the tiller in my hand and put it under my elbow. Then I can steer and paddle at the same time.
paddling with a double blade paddle, when I do that I use the seat here, which doubles as a roller for when I have to move the boat up a rocky shore
Towing, I can fix the tiller in the middle or on the side, so I can get out of the boat and pull it as I walk

Under deck
My boat has big airbags front and back, with pool noodles on the side. This system is tried and tested. 41 seconds after a capsize the boat can be upright and sailing. It takes another 4 to 5 minutes with a 4 litre bailer to empty the boat out. With a good level of fitness you can capsize and re-enter 4 to 5 times until exhaustion sets in.
The self-bailer is nice for when the boat planes downwind. Things get very wet. The self-bailer starts to work at 4.5 knots of boat speed.
Under the front deck there is a storage bag for water and food, the gopro and other items. Under the aft deck there is a neoprene bolero of 7 millimetres thick. It is great when a squall comes.
My luggage is stored in a box which is called a wannigan. It is completely waterproof. The wannigan doubles as a seat while underway.

Floats/Amas
I use floats for extra safety at sea, and to give me a rest on longer trips. The floats allow me to visit the bathroom, keep the boat stable when reefing, check the map and have lunch.
They are bought for 80 euros via Amazon. I love, and hate them.
They should ideally never touch the water. They have never failed me, and give me peace of mind on bigger water. They are easy to take off and can be stored inside the canoe.
But after rough use for three years the connections are starting to wear out. They slow me down because the underside is too fat and they are too close to the water. Also, I think they are ugly.
So, I have ordered plans for new ones from Michael Storer. They are plywood, and will cut through the wave tops better.

I have now used and developed this canoe for 7 years. It did well to travel safe and fast in many countries. Artemis has also helped me win many races.
