We just disembarked the Wind Surf yesterday in Saint Maarten after our TA crossing from Lisbon. Having dinner with a few of the officers, we were given a sneak peak (we were asked not to post anything on social media until it was published) of their upgrade plans. We are very pleased with Windstar's commitment to keeping their ships up to date. Like Jazzbeau mentioned about Celebrity, the WS's officers feedback was taken into account with the planning/design process.
We look forward to seeing/experiencing their sailing ships when it's all completed.
Cheers!
