What our clients say
Recently we had the pleasure of undertaking the challenge to completely refurbish a Formula 233. To say everyone was more than pleased with the outcome is an understatement. When only the best will do, get the Dream Team from Cosine Marine! We just completed a full rebuild/refurbishment of our beloved Formula 233 with the talented shipwrights from Cosine Marine.
Thanks for fitting me in with such short notice. It was a job well done and the result is far better than how it looked before.
Carl and the team from Cosine were great to deal with.
