    If you scroll back through these posts you get most of the refitting and initial build. I had this type of boat in mind for quite a while but Matt put a 20ft limit on the length and needed to build in ply to keep the weight down. As a pedal/sail boat it became a bit of a camel with not enough length to carry the weight to make it a decent sailing boat. A little bit bigger and it would easily foil. Matt only ever got 10kts from it sailing. https://www.facebook.com/Teamtakemetothevolcano/?fref=ts This year he reduced weight by removing ply and using PVC marine foam instead. It is now just a little lighter than design weight. It still has the ply main hull. The shape is deceptive because the cockpit overhangs the hull by more than 100mm each side. The BWL is 334mm. It has a tiny transom. The prismatic coefficient is 0.61. The hull is optimised for 180kg at 6kts with the 20ft length constraint. It is lower drag than any round section hull for that displacement and length. The prop is on a curved shaft that requires 4.5N to hold its curve. In operation the prop provides that lift rather than the strut. So in operation the uplift from the prop is very close to 1lbf - not much.

    Both the prop and rudder are out of the water so just the hull for drag. The SUP paddle gives him the option to stretch his legs and keep moving. He can hold 5kts with heart rate under 100bpm so he is not working very hard but laying on your back all day spinning your legs can get boring. Need a change of pace to stay awake. If the weather stays calm he may do better than he expected.

    Here is a nice photo of Matt with the boat.

    Wanted to see if this short video that Colin Angus took will display here:

    Another error with the tracker is listing Team Take Me to the Volcano as a rowing boat. It is a pedal boat named Rouleur - and hopefully keeps up the performance consistent with its name.

    You can check the actual time of the update by hovering over the name and it will show the time of the update. The positions in the image above for Take me to The Volcano and TRAK Kayaks are both at 20:10. The SPOTS update every 10 minutes but sometimes they miss the update on the tracker. It appears there is no automatic update of the leader board. It is all over the place.

    The tracker is unimpressive. If you hover over the team name you get the time of the update. If the update times are the same then the positions are not too bad. However if you want to be certain of the position use the track function as the boat symbol is not always at the top of the track. In the screenshot below Matt has done a backtrack on the tracker, which he obviously has not done>

    Going 7 miles in the wrong direction and taking the crap shoot that you can make the corner is a risk. I've pulled it off, and made out like a bandit, but that was when a decent northerly was expected to fill down the Straits. I've also missed that move and sat there in the huge counter current that builds along the Tumbo Island shore, while boats had a pleasure sail up Trincomali´╗┐. ´╗┐ PT Watercraft is a reasonable motor sailor. That gives Russell ability to point high in light winds or go straight upwind if the breeze is light.

    The big benefit is ability to motor sail. A little extra thrust from the pedal drive can make a big difference to apparent wind and just get the sails drawing nicely. That is a compounding factor and the boat just goes faster. I doubt he would pedal above 6kts though because he could not spin fast enough. According to the wind map he is moving into lighter winds so he should slow somewhat about half way across.

    Matt has spent a lot of time in these waters so I think he will have a plan for the conditions. He may want to get north before the ebb reaches its peak but it is a short ebb. Flood tide starts at 9am. That will help boats going north later in the day. http://www.deepzoom.com

    The tracker seems to be slow to update. I watched them start on the PT webcam. Most of the boats are now out of view at 5:17 PT time.

    It looks like they are away so maybe they did start at 5am.

    They are still milling around the start line. They have delayed the start in precious years.

    Yes 5am - the turn of the tide. I think they have two days to get to Victoria. I expect you would need to cross the start line in time to realistically meet the finish deadline.

    Matt Johnson (Take Me to the Volcano) is pure pedal this year and plans to go all the way. Rouleur has been on a diet. The only ply remaining is in the main hull. The cockpit is now all PVC foam as are the stabilisers. In the testing, without provisions, he could sustain 5kts with heart rate under 100bpm. Matt has done some on-water testing. His drive has previously covered more than 100nm and he has checked it over but I am not sure of what he has renewed. The curved shafts will fail if not set up well. I think he will carry a spare for that. Mark Dix with the Tornado has fitted pedal drives on both hulls so he can choose to load one hull for either righting moment or reduced drag and still pedal. It should be a true motor sailor. Mark intended to sail to PT as a test run but the shakedown will now be the crossing to Victoria as he ran out of time - who doesn't? Anyhow I will follow the tracker with interest and best wishes to all for a fast, fun and safe journey. The race is a brilliant concept held in a great part of the planet.
