+{{:outrigger-canoe:newyears2019:dsc_0369.jpg?600|Stern and steering oar closeup}}
+//The steering oar has a line wrapped around it, ending in the cleat. Effective and pretty quick to swap sides. In practice the oar was usually just trailing in the water, not needed to steer the boat on any point of sail. We found the forked sticks on the beach.//

+{{:outrigger-canoe:newyears2019:dsc_0373.jpg?600|Long distance trailer setup}}
+//For full speed travel I still like to fully disassemble//
+Below are some gps tracks of the four days of sailing. Wind was generally pretty light. Upwind travel didn't feel very efficient, but the tracks show pretty consistent upwind progress. As long as I kept out of the tide! The only thing preventing leeway is the hull shape. Although a leeboard is shown at times, this wasn't balancing right with this sail, and caused the boat to bear away.
+The striped regions on the map are tidal, sand banks at low tide. I was at times sailing in knee deep water, including upwind!

 ====== Lake Ngaroto (9 Jan 2015) ======
 Everything was still sitting on the roofracks so went for a little sail today on Ngaroto. No changes to the boat since last time. Winds were very light, maybe 2 to 5 knots or something. Enough to keep moving and keep the sail filled the whole time, and perfect conditions to improve technique. Unlike the last time, the boat was perfectly controllable by adjusting the centreboard, weight shifting and playing with the mainsheet. Paddle still needed for dead downwind though.
 Shunted more than 10 times both up and downwind, with no problems. It's a bit like tacking a windsurfer, with the boat pivoting around the leeboard as the sail is moved across. I've been watching some videos to see how the experts (polynesians) do it, and it works very well! Sailing with the tacking rig at Kawhia was a lot less smooth, with vigorous paddling required for every tack.

 ====== Kawhia Trip, around New Years 2014/2015 ======
 Took the outrigger canoe to Kawhia for a little holiday. On 28 Dec tested out the new ama and lateen rig. Very nice! I tried using the "lee-rudders" again, but still found them very annoying to use. Not a lot of wind, but video to come!
 I then reconfigured the boat to have a single leeboard for use with the tacking rig (white and blue lateen sail). Sailed it at the same time as a regatta, so I kind of sailed along around the sandbank. Speed downwind was similar to the Hartley 14's. Reaching slightly faster. Upwind at times I was going the same speed, but tacking with the paddle was very difficult, so at times I stopped or slowed down to let people pass so as not to be annoying.
-The wind was probably 10 to 15 knots, and the cross beams (severely cracked bamboo) were making some suspicious sounds! The main problem was hiking out hard while still paddle steering. This made it virtually impossible to sail a close reach. On one broad reach I hit a top speed of 18.3 km/h (9.9 knots) with the ama flying. Not bad for a 4.5 m<sup>2</sup> sail. The total distance was 8.3 km.

 The other problem was the mainsheet, which was rigged a bit stupidly. This meant there was a lot of force on it. All in all it was a great sail. At times I had the ama fully submerged, or fully flying on the other tack. On a few points of sail I was also able to steer without the paddle, allowing me to hike and get some good speeds.

 ====== Bow tanks (Christmas 2014) ======
 Between Christmas and newyears 2014 I also replaced the inflatable mattress floatation with some built in buoyancy tanks at the bow and stern. Yet to be tested!
 ====== New Ama (Dec 2014) ======
 The new ama has replaced the old pvc pipe one which was just not heavy or floaty enough. It worked, but it made everything unnecessarily difficult. The new ama was made by "reconfiguring" and old windsurfer. The construction was some kind of thermoplastic over foam (probably polyurethane). I cut the stern of the board off, cut that in half again and joined the two pieces end to end.

 A deck was cut from 20 mm plywood. I carved the foam out from the top of the ama to allow the deck to sit on the foam, inside the plastic skin. A recess was carved into the foam in both halves allowing a wooden joining piece to be inserted at the keel. A couple of gunwales were put on, these clamp the skin to the deck, with a bunch of screws and silicon sealant (real high class stuff). Finally some supports for the ama were put on.

 My sailing club has an away weekend to lake Arapuni every year, during a time where water quality and wind at our lake are usually dubious. Lake Arapuni is a long hydro lake with high rock walls on both sides.

 It was raining when I left home, and I wasn't expecting much luck with the wind based on previous years. I therefore loaded the boat onto my new experimental roof rack, but left the mast and sail at home.

 Of course when I got there, and it stopped raining, the wind was straight down the lake and perfect for sailing! Luckily there was an optimist rig which I could use on the boat. But how? I could rig up some stays and step it on the gunwale, or step it into my existing mast step. This would have left the boom extremely low. I therefore decided to make a little stub mast.
@@ Line 121: / Line 160: @@
 I went looking for some suitable stub mast material, and of course nature provided! To be specific, I found a discarded party tent with a steel folding frame. The corner posts fitted almost perfectly inside the opti mast! I added some spacers from inner tube, and a big collar of inner tube to prevent the mast sliding too far down the tube and wobbling around in the mast step.

 It worked perfectly! Had a nice sail in the afternoon breeze, and the sun had come out too! I could even tack the boat by shifting my weigh around without using the paddle. I then went for another sail with two people on board, which worked very well. Still sailing faster than a single adult in an optimist.
@@ Line 131: / Line 170: @@
 Of course things weren't that easy. We first had to slightly enlarge the mast step and mast partner to fit the mast. Using a square file and pocket knife we got this done, although the result isn't the most beautiful carpentry job ever done. The burning sun didn't help make this a more enjoyable task either!

 We then shifted the outrigger closer to the main hull, so that about half a meter of beam projected on the other side. The side stays were tied to the front beam, and the fore stay to some holes in the front of the canoe. A pulley from the optimist was tied on to give a 3:1 purchase on the main sheet. And were were good to go!

 We bravely set off from shore, ignoring the little voices in our head. The wind was around 10 knots at this point, and a little gusty. We had to paddle a bit to get away from shore, and promptly almost capsized both ways multiple times. It was not very stable, to say the least! The boat had quite a lot of weather helm, and we had to sit right back to get some control and stop rounding up. Whenever a gust hit, the outrigger would promptly submerge, usually only up until the reserve flotation/buoyancy bottles hit the water. Which would slow us down dramatically. Not long after leaving the shore we had our first near capsize (well, we were constantly on the point of capsize really), when the boat almost tipped over 45 degrees. It didn't actually feel like that far, and the monkey like antics of the crew saved the day somehow. But the video footage does not lie.

 After lunch we re-distributed and tied in the buoyancy, and attached some paddles and sticks in strategic locations to try to hike out on. We did a capsize test before we set off again, and were happy enough with the result. Around 2 minutes of bailing would see us on our way again.

 This time we were really flying! We got the hand of controlling the beast and only capsized three more times, each time when the mainsheet would jamb for some reason. We still didn't have a hiking bench or anything, but basically leaned out of the hull like it was a dinghy, holding on to the beam or stick like object lashed to it. The second capsize I heard a big crunching sound. I thought the bamboo beam had finally snapped, but actually it was a wooden paddle which the crew fell onto. Big relief.

 I've been considering how to sail this thing the last week or so. I have a sort of crab claw sail made up, from an old micron sail. The proportions don't really work out, the sail needs to be really high to get the centre of effort in the right place I think. And then there's also the shunting problem. I'm keen to try keeping the rigging to a minimum, so just going up to the bow, grabbing the sail and walking to the other side. But I'm screwing it up even on the lawn, so on the water will be a little difficult I think. Going to try adding some backstays first, then see how we go.
