Manta 19 - Longest Journey of a Manta 19?

Mekicevica's 2014 Sailing Adventure

From Zeeland to the Waddenzee and back. This tiny boat was my home for four weeks, and for some of the time also of my First-Mate. During this period we covered over 360 miles, sailed delightful waters, and visited wonderful places.
Could this have been the longest journey ever on a Manta 19?
