Eine Mini Transat mithilfe von Spitzentechnologie für Simon Koster

Simon Koster wird am 1. Oktober zu seiner dritten Mini Transat – La Boulangère aufbrechen. Der 29-jährige Schweizer Segler arbeitet seit zwei Jahren sehr hart auf diese Regatta hin: Anlässlich der Mini Transat 2015 erreichte er mit seinem Boot, welches die Fertigungshallen der Schiffswerft nur gerade einmal drei Monate vor Rennstart verlassen hatte, den siebten Schlussrang. Simon tritt heuer mit gleichen Prototypen an, seiner Eight Cube SUI 888, welche ein radikales Design und einen runden Plattbug aufweist. Das in der Auflage 2015 als gewagt und experimentell geltende Boot, ein Einrümpfer von 6,5m Länge, wurde in den vergangenen Monaten modifiziert, um eine höhere Polyvalenz zu schaffen. „Das Boot hatte am Wind sowie bei Schwachwinden Schwächen“, vertraut uns Simon an, welcher mit der Schiffswerft Mer Forte von Michel Desjoyeaux zusammenarbeitet. „Es wurde in den verschiedensten Bereichen modifiziert um die Schwachpunkte zu verbessern, Einstellungen zu verfeinern und das Boot robuster zu machen. So wurden die bisherigen Foils durch Schwerter ersetzt, das Gewicht verringert und das Boot vereinfacht.“

« Prepare for the perfect day ! »

Twenty days alone in the middle of the ocean: this is what Simon will live this autumn. An extraordinary technical, but also psychological and mental endeavour!

Preparing the boat and the technical aspects of the race is one part. Preparing the man is the other one. For this crucial aspect, Simon has been working with ONEDAY coaching for the past three years. His coach, Thomas Theurillat, tells us how they prepared for the Mini Transat.

« When we started our collaboration, I spent 24 hours with him while he was building his boat; I wanted to see how he behaves when he’s tired. The challenge in this regatta is not only about sailing, it’s also about self management. The difference won’t be made only by sailing, but by the sailor who is the best at self management ! It’s not a marathon, it’s an ultra-marathon.

Safe and sound in La Rochelle

10 days to go before the start of the Mini Transat – La Boulangère ! Simon Koster and his Eightcube safely arrived in La Rochelle last weekend, and joined the others Mini 6.50 in the Bassin des Chalutiers.

Simon has an intensive schedule until the start, on Sunday October 1 : safety breaking, stickers on the boat and the sails, last technical tuning, and of course some rest to get ready for the short nights on the boat !

On Sunday 24 of September, he will sail the official prologue alongside the 80 other Minis. We remind you to follow his Facebook page, where we update daily news and pictures, as well as the official Mini Transat Facebook Page with many news and pictures from La Rochelle.

A High Tech Mini Transat for Simon Koster

Mini Transat – Iles de Guadeloupe 2015

[German and French version below]

Simon Koster will take the start of the Mini Transat – La Boulangère on 1 October 2017, his third participation. The 29 year old Swiss sailor has worked relentlessly for two years: in 2015, he came seventh of the Mini Transat, despite his boat only being completed three months prior to the start of the race. He is back with the same scow bow prototype, SUI 888. A daring and experimental choice in 2015, the 6.50m boat has undergone further developments to increase its versatility. “It was weaker upwind and in light weather”, explains Simon, who has worked with Michel Desjoyeaux’s shipyard, Mer Forte. “Changes have been made to increase performance, perfect the design and improve preparation. The foils have been replaced by daggerboards, and the boat has been lightened and simplified.”

888 not on the Start line of the Mini en Mai

After the last race the Pornichet Select where I had a lot of trouble on the last upwind part of the race with boatspeed and height, I found my answer during a righting moment test we did the following week. The test included pulling the boat on it’s side to be able to mesure the load pulling upwards on the mast top when the boat layed flat at 90 degrees to be able to optimise our keelangle and keelwheight. With the boat on ti’s side i could see that the cover over the keelshaft was riped open and hanging loose on one side. This cover has no structural function it is only there to cover up the rectangular part of the keelshaft when the keel is extended and canted.

I am not to sure if I am happy that i found the reason why I wasn’t fast at the end of the pornichet select or if I should be annoyed by the broken piece. It confirms for me that if I can get the last flaws out of the system the boat can play in the top end of the fleet.


The Problem is that the carbon keelshaft has some flex that puts a lot of pressure on the cover and it fails over time. We fight with that problem since the launch of the boat, we tested 3 different solutions already: stiff carbon, fibreglass, soft epoxy… Now we need to find a solution which solves the problem once and for all.

Because this takes time I decided not to take part in the Mini en Mai, I regret not doing this race but it is important to solve that issue now to be confident on the Minitransat.
