Silverrudder 2025

Mission accomplished, Proasis is officially the first proa design ever to finish the famous Silverrudder race! I made it from Svendborg to Svendborg after 34 hours, 38 minutes and 17 seconds after sailing a distance of approximately 135 nm. Here is a detailed account how I experienced the race:

Leaving the Svendborg sund just after the start

Due to a very bad weather forecast a week ahead of the start—the first storm of the season had just passed through—I decided to sail Proasis to Svendborg two weeks early. When I arrived, the harbor was almost empty, and I think Proasis may have been the first boat there.

Two weeks later, when I returned, the contrast couldn’t have been greater: the harbor was packed, and Proasis was already attracting attention thanks to her unusual look.

The Thursday before the start passed quickly with last-minute preparations and many enjoyable conversations. The wind was still strong and gusty in the wake of the storm, but it eased slightly overnight, setting the stage for the days ahead.

The next day the race began for me with waiting. With more than 400 participants, the Silverrudder fleet is divided into groups by size and type (monohull or multihull), each starting 30 minutes apart. The smallest keelboats go first, and the largest multihulls start last.

Proasis, competing in the small multihull class, was in the second-to-last group. Watching all my friends head out while the packed harbor slowly emptied felt strange—like the party had already started without me.

The start itself was rather unspectacular. Only 12 boats made up the small multihull class, and I took it easy, assuming they would all be much faster anyway. To my surprise, I soon found myself in a duel with Tim on his Dragonfly 25 and even managed to pass him for a while.

The course east of Fyn, between Langeland, began as a downwind reach. With flat water thanks to the offshore wind, the conditions were practically tailor-made for Proasis. Still, the gusts remained strong, pushing well into the mid-20s. One after another, boats blew out their downwind sails.

At first, I was cautious, holding back in the gusts. But when TRI—one of the large trimarans and eventual overall winner—blasted past me at double my speed under a massive gennaker, I thought: screw it. I hoisted the kite myself.

The effect was immediate: Proasis took off like a rocket, hitting 12–13 knots in the gusts and averaging 9–10 knots. The long reach to the northern cape of the island turned into the fastest stretch I have ever sailed on her.

Passing the large belt bridge, Friday 15:47

After passing under the Great Belt Bridge, I had closed the gap to the extra-large and large keelboats and was ripping through the field like a jet on afterburner. Proasis was in her element, and it felt incredible to carve through the bigger, heavier boats at speed.

By the time I reached the cape, I had already overtaken the first of the small keelboats—despite the fact that they had started two hours earlier. The realization that I was reeling in boats from multiple classes gave me a huge boost of confidence and made the leg even more exhilarating.

By this time the wind had eased considerably, dropping to around 15 knots. From here on it was close-hauled sailing all the way to the Small Belt—and the clock was ticking. The Small Belt is notorious for its strong tidal currents, and the forecast predicted the flow would turn from favorable to unfavorable around 2 a.m. My goal was clear: get there early enough to slip through the narrows and under the infamous bridges before the tide turned.

But the wind kept softening: first to 12 knots, then 10, and eventually just 8. That range is where Proasis struggles most—her sail area is too small and her sail shape less than ideal. One by one, the keelboats I had stormed past earlier began creeping back up, while I could not managed to hold position with the other small multihulls.

Still, the sailing had its own reward. Under a calm, starry sky, the Milky Way arched brilliantly overhead, and I even caught a few shooting stars. Despite the frustration of slowing down, it was one of those rare, beautiful nights at sea that makes the effort worthwhile.

Arriving at the entrance of the small belt around Saturday 2:00 after some long upwind legs.

Unfortunately, time was working against me. By 2 a.m. I was only just approaching the entrance to the Small Belt, and I could already feel the current turning against me as I tacked up the narrow water under the first bridge.

When I reached the old train bridge, the scene ahead looked almost surreal. The water was filled with moving lights—mostly white, occasionally flickering to green or red. As I drew closer, the reason became clear: just below the bridge the wind had died completely, and those half of the fleet that had arrived too late, like me, was stuck in the current, drifting helplessly backwards.

To cut a long story short, we spent the rest of the night drifting. After a few hours, Proasis was pushed onto some piles near the shore. I took the opportunity, tied up to them, and decided to wait out the tide rather than lose more ground. It was a humbling pause in the race, but at least I was holding my position until the current shifted.

Tacking into the small belt and getting stuck there in no wind and opposing current (approx. Saturday 2:30 – 8:00).

Unfortunately, the expected tidal shift never really came. The strong southwesterlies of the previous days had disrupted the pattern, and instead the wind swung further south while dropping to a whisper.

The result was a long, grinding Saturday. All morning and well into the afternoon I was forced to tack endlessly against both the current and the light breeze. Progress was painfully slow, and every gained mile felt hard-earned. It was a test of patience as much as sailing skill and physical endurance.

Clearing Bagö after a horrible upwind beat in light wind and opposing current (8:00-15:30)

After clearing the island of Bågø, the wind finally picked up just enough for me to point directly where I needed to go. For a short while, it felt like the tide had turned in my favor.

But the relief didn’t last. From the west, a dark front of clouds rolled in, bringing first a curtain of pouring rain and then hammering gusts of wind. I can’t say for certain how strong those gusts were, but they were fierce enough to force me to reef down as much as possible just to keep Proasis under control.

The contrast was stark: from creeping along in light airs to suddenly battling through a storm line, the race reminded me once again how quickly the conditions over here can change.

Clearing the south-western cape on route to Svendborg (18:30).

Considering the duration of the race, the numerous shunting maneuvers over the past day, and the lack of sleep, the reefing pushed my exhaustion to the absolute limit. Even worse, just 15 minutes later, the squall was over, and I had to reverse everything…

At least from this point forward, I knew I was on the last 20 nm to the finish line, and this stretch was entirely downwind. Unfortunately, time was ticking again: the Svendborg Sound is known for very strong currents, and just before the finish line there is a bridge with narrow gaps between the pylons. So, just before sunset, I set all the sails I could to somehow make it before the tide turned. Unfortunately, I have no photo, but for a while I was sailing under two gennakers at the same time, rapidly approaching the finish line.

Fortunately, I got lucky and passed the bridge just at the moment when the current shifted, making it over the finish line without any issues after 34 hours, 38 minutes, and 17 seconds.

Just arrived in Svendborg.

My only goal was to make it around, so mission accomplished. If I had been a bit luckier with the timing in the Small Belt, my time could have easily been 6–8 hours faster. But well, that’s part of the game.

Would I do it again? Maybe. It really comes down to the weather and whether it makes the race fun or not. I think we got pretty lucky this year.

The past, the present and the future

Throughout June we had the great pleasure to host Alson Kelen, director of Waan Aelon in Majel (WAM), in Germany. Thanks to Dorothea and Leonie of the Humboldt Forum in Berlin there was time and funding to explore the traditional Marshallese outrigger canoes that were brought to Germany in colonial times. These vessels are, to our knowledge, the only surviving examples of their kind from this time. There is even a complete sail from woven pandanus leaves, just incredible and definitely one of its kind.

Combining our respective expertise in traditional knowledge, pacific anthropology, conservation and engineering we learned lots of interesting new things from these artifacts. Connecting past to reality we also managed to spent a weekend in Kiel, catching a ride on Proasis as well as Ri Nei Jeim, a 6 m canoe built by Isocker Anwell (WAM) in Den Haag.

Last but not least we also had the chance to look into the future by conducting towing tests with scale models of the old canoes from the museums at the towing test facility of Hochschule Emden-Leer (HEL). The goal is first of all to get a better idea of how the old canoes might have sailed since nobody alive has ever tried. The knowledge (in particular regarding the asymmetric shape and keel outline) will also be applied to future designs in the ongoing collaboration with WAM to build more efficient sailing vessels for emission free lagoon transportation and fishing.

Silverrudder – Challange of the sea 2025

Sorry for the lack of updates in the recent months. Proasis is on the hard for the winter and we have been very busy in Uganda supporting the Musana Ferry Project.

Nevertheless, for 2025 we have a big anouncment: Proasis is registered for the Silverrudder, a single handed race around the island of Fyn. As far as we are aware of the first proa ever!

We are proud to dedicate this race to Waan Aelon in Majel (WAM) and start under the flag of the Republic of the Marshall Islands.

End of sailing season

Unfortunately last Sunday’s sail will be the last one for this year. Winter has been kicking in recently with the first ice and increasingly nasty weather. We got lucky to pick one of the rare sunny days with a good southerly breeze for the 15 nm trip from Kiel to Surendorf. After little over 2 h of beautiful sailing we sat Proasis on the beach and took everything from the boat that we dont want to keep on it for the winter. This is always a good moment to realize how much unnecessary stuff gets piled up over the year!

To move the 700 kg canoe up the beach to its parking spot for the winter (about 200 m) we built a solid slip trolley from steel with six huge balloon tires borrowed from regular dinghy slip trolleys. Using an ancient electric winch with a long cable this is an surprisingly easy job that can be done by three without problems.

Since there is no sailing for the next couple of month there is plenty of time to work on Proasis. We didnt break much over the year and there is no other need for major refits so we can focus on improvements. We have some projects in the pipeline but its still to early to go into details. Just so much, they are all about speed 😉

Proa Meeting 2024

This year we hosted our informal German proa and outrigger canoe meeting at our beach in Surendorf. Like the year before we had five canoes on the water:

On the first day we had a fresh onshore breeze with a little shore-break and choppy conditions. Sailing was a lot of fun. Below you can find a video of Lars and Reto racing around (other canoes parked at the beach to get the hands free for the drone):

First day with fresh breeze and choppy onshore conditions.

By the next day the wind had died completely. at least we managed to get all five canoes on the water at the same time for some fleet sailing (well, more drifting):

Second day, no wind at all

Downwind upgrade

Due to the rather small sail area (just 19 sqm) and the design of the sail (the shape only forms under wind pressure) Proasis has always been a bit slow in light wind from behind. We thought about getting an additional downwind sail for a while an now finally got hands on a good second hand asymmetric spinnacker. Finding one that fits our short mast was not easy but apparently we can conveniently use the sail of a Hobie 15. It’s just 6.5 sqm but gives a notable boost of thrust. It can be hoisted either on the leeward bow if the wind is blowing more from the side or to the windward bow if the wind is dead from the aft.

Downwind mode for wind right from the aft.
Regular mode for apparent wind from 90-170 degrees.

Midsummer sailing

Midsummer is a very special time in the northern hemisphere. It marks the summer solstice where the day becomes the longest day of the year and the night the shortest one. Although Kiel is not located north enough to experience midnight sun, the event is still quite impressive. The sun just dips behind the horizon and is visible as a golden light for the entire time between sunset and sunrise. We thought the best way to experience this magical night would be to sail Proasis through it. The weather was fortunately fair with light wind and a lightly overcast sky, turning this trip into a great adventure!

Spring refit 2024

Better late than never – this years spring refit is almost finished and we hope to relaunch Proasis next week. The intense work of the past couple of month included the regular winter work such as bottom paint and minor general repairs/maintenance as well as three four major upgrade projects:

  • Two new bidirectional centerboards with internal cases in the leeward hull. The boards are set about 80 cm to each side of the middle of the hull. This allows to adjust the balance of the boat by adjusting them. Pulling up the aft one will make the boat turn upwind, pulling up the front one downwind and vice versa. We’ve already tried this on a WAM Proa in the Marshall Islands with great success and adopted it as standard design. For Proasis we expect a better upwind performance as well as an even better balance for singlehanded sailing.
  • A new solar array, wiring and a LiFePo battery. We replaced our old, crappy solar panels with something better and more durable and upgraded from a PWM solar charger to a Victron MPPT. Combined with a 1kWh LiFePo battery we hope to get a more powerful and long-lasting setup.
  • A new slip trolley. Proasis weights about 750kg and we have to move her about 250 m over a soft sand beach twice a year. Without any access for power vehicles thats quite a challenge. For this year have designed a trolley from galvanized steel with six huge balloon tires on ball bearings. Lets see how good that works.
  • Replacement of the beam lashings. Proasis is kept together by rope lashing around the beams and the hulls. Since we launched her for the first time we have never replaced or adjusted them so it was about time. We used the opportunity to carefully measure and realign the hulls and replace the old shock absorbers from rubber.
