Crossed the North Atlantic from Ireland to St Pierre and Miquelon on Insignia June 2017. At least 17-20 foot seas for 5 days! I will not tell you it was comfortable however with waves hitting the 10th floor windows Insignia did just fine. Captain slowed the ship to a slightly lower speed for passenger comfort and we missed our covered St Pierre port which was very unfortunate but...I love this ship. We will spend 77 days crossing the Pacific next year in sister Regatta.
