Hey guys, I know this is decades late but the font is called Bauer.

Thanks for chipping in Joe. The Wellcraft Scarab logo is inspired by Bauer font, but not all letters are Bauer. It's a brand custom logo. Another curiosity is that Larry Smith's Team Scarab boat logo was inspired by and paid homage to his late friend Lance Reventlow's Grand Prix race cars and was totally different than Wellcraft's Scarab logo. For best help to keep one's Scarab boat brand logos correct, contact Team Archer, Costa Mesa, CA for professional services.
