Customer Reviews

Gave me the confidence I needed.

Joni Gibbons

I would highly recommend Sail Squad. Really professional and friendly, extremely knowledgeable.  We’ve had two great weekend courses where we’ve learned loads.

John Turner

I’ve done a few training courses with different companies, and this has honestly been the best one yet. Patient instruction and high standards of boat and abilities.

Seb

This is a class act! The quality & breadth of info, combined with so much practical tuition, means attendees leave with a really solid grounding and confidence to handle boats in many conditions. Excellent – and so much fun!

Paul Lockett

This course should be mandatory for all new day skippers! It has cemented knowledge and highlighted gaps in my ability. The instructor was fantastic. The boat was excellent. I will be back.

Ian Roberts

This course should be taken by all new day skippers. Excellent experience and a great instructor.

Sarah Roberts

Lucy was very good at putting everyone at ease with the boat. Very clear instructions and reasoning behind the theory, and lots of practice in all aspects of boat handling. Felt completely safe in her hands. Thank you for a lovely week.

Nicola Neil

I found Lucy to be a competent and experienced instructor who gave us 100% throughout the five days. A really enjoyable course, and I will certainly recommend Sail Squad and Lucy to friends and anyone else wishing to start the sailing/training journey.
