I can tell you ,I mixed polyurethane with minwax old english chesnut and was able to exact match the interior finish it looks factory. The face board at my nav desk in picture was made from solid maple and that mixture appliedOur son had the same boat once - it was polyurethane
I refinished the stairway / ladder with Minwax helmsman spray polyurethane.I need to refinish the cockpit table in our Beneteau 473. Is the finish a varnish or lacquer?
Sounds to me like that would be different from the interior wood that most of the replies are about.the cockpit table
