Introduction

Hello,I'm Doug and I just discovered this forum and its wealth of info. I've been active in the EV car world for 4 years now, and have continually watched the marine industry make its inroads with electric propulsion over the past several years. I think I'm ready to make the commitment to electric for my Nonsuch 30 "Such is Life"  currently moored in Anacortes, Wa... but soon to relocate in Everett Wa.Having her closer to home will allow this type of major retrofit to happen.
