LAGOON SEVENTY 8 WEBINAR WALKTHROUGH
In May TMG The Multihull Group hosted a walkthrough webinar of the Lagoon SEVENTY 8. The tour was advertised to the world with many virtually coming aboard and asking multiple questions.
We recorded the entire webinar and cut it down slightly for your viewing pleasure. We realise this is EXTREMELY long, however we wanted to make sure we covered EVERYTHING. With such a massive boat with so many options and extras we hope this video answers most of your questions.
