Definition of evergreen :

– a plant having foliage that remains green and functional through more than one growing season

– something that retains its freshness, interest, or popularity

If there is a small yacht that deserves to be called an evergreen the Greenline 40 Hybrid surely qualifies. Twelve years after her launch in 2011 and after more than 100 units delivered this model not only matured but actually

gained on actuality and is attracting more market than ever. This decade also brought much better understanding of actual use and advantages of such a hybrid boat . Udo of Greenline USA is explaining how

the Greenline 40 Hybrid will improve your boating experience and life aboard in this interesting video made in Florida. The video clearly explains how such a small yacht not only makes your boating responsible and sustainable

but  improves your fun and convenience aboard at the same time. J&J Design as the founder of Greenline created the 40 and invites you to watch at the link:
