Role: Flight Controller

Rasmus’ passion for sailing ignited at an early age, where his family introduced him to the sport. Since then, he has experienced an illustrious career spanning some of the biggest events in sailing – and now adds SailGP to his impressive resume.

Buoyed by several national championship wins as a youngster, Rasmus climbed the rankings of the World Match Racing Championships – before earning his place on the World Match Racing Tour and RC44 circuits.

With valuable match racing experience under his belt, Køstner joined the Italian challenger, Team Mascalzone Latino Capitalia, for the 32nd America’s Cup in 2007 – and Ericsson Racing Team as an In-Port Race tactician in the 2008-09 edition of The Ocean Race.

Køstner then switched focus to high-performance multihull sailing, where he founded the SAP Extreme Sailing Team that finished second in the 2015 Extreme Sailing Series, before taking the title in 2017. He brings an abundance of valuable experience to the Danish campaign in 2020.

Rasmus is water repellent

The athletes on Team ROCKWOOL Racing tried to figure out which team member fits each of the seven strengths of stone the best. Rasmus was nominated as 'water repellence' by Nicolai!


Rasmus is extremely driven and focused which is a great characteristic for any top-class team. As the Flight Controller on board, he spends a lot of time looking down at the numbers – and he has nerves of steel and lets the pressure just wash over him.”

How does ROCKWOOL harness this strength?

Stone wool can be designed to repel water and not absorb it. This protects buildings from rain and moisture, keeping homes comfortable and healthy.
