WIND

• DIFFICULTIES

• 2-3 of our radiationcovers have been destroyed by hard storms this winter.

• Still no TurboWin on our ships …

CHALLENGES• To find out a new smaller radiationcover,

which manage to take hard winds but also the shipvibrations better.

We think we just have find one …

• To implement TurboWin. We are waiting for the ships to get Internet which will happened this or next year.

• To recruite 2 more wessels.
