Absolutely fantastic AEC1 course with Hannah and Derek at Seagrass Marine! From start to finish, the training was engaging, professional, and incredibly well delivered. Hannah and Derek are both extremely knowledgeable and experienced, but what really stood out was their ability to make the course enjoyable and easy to follow. They created a friendly and supportive atmosphere where everyone felt comfortable asking questions and getting involved. The practical elements were excellent and really helped build confidence, with plenty of opportunities to apply what we'd learned in realistic scenarios. Their passion for what they do was clear throughout the course with Derek taking care to ensure we all understood everything and this made the learning experience genuinely enjoyable. I also enjoyed the bottomless tub of chocolate biscuits. Thank you both for a brilliant few days of training.
