  1. Al

    Great service in the ordering and delivery process. The ladder quality and workmanship looks excellent.

  2. Peter Robertson

    I just want to say how pleased I am with the Mast-S ladder (12.1m). I have already used it twice. Once on my own boat to fit the masthead instruments and also on a friend’s boat. The shorter step height was ideal and the ladder felt very secure. Using a bosun’s chair as back-up, I was able to stand shoulder-height to the masthead with both hands free to work – excellent! Pre-order communication and advice from 4yachts was most helpful. Delivery was very fast indeed. Thanks.

  3. Neil Fuller

    Easy to order and arrived quickly. It seems like a well made product but yet to use in anger. I fitted my own A009 slides which fit my mast. If you are in the UK beware you will get hit with import duties and duty handling fee which was £45 for me on top of the price and had to be paid to Fedex before they would deliver.

  4. Gary

    Excellent product, professionally made. Also purchased the luff slides, products promptly shipped without any problems.

  5. Bjorn

    I got this in in three days from Poland!! Everything was super high quality and works like a charm. I was quoted 480 to have my rigger climb the mast one time. I think I am well ahead of the game with this ladder. I have a safety harness with a shock arrestor as back up to the spinnaker topper, via an ascender. Definitely use a back up harness! But otherwise a safe and easy way to get up there.

  8. Rob Verschoor

    Quick reply on questions by Mail, smooth order proces and quick delivery, The ladder quality looks excellent.

    This must surely be the best thing since sliced bread, and even more so when the fantastic price is taken into consideration! I feel so much safer now climbing the mast, especially when I am being lowered. The (MastS) steps are very well spaced. The sliders also fit perfectly on my boom furling mast track. I placed my order on Friday, and received the item on Monday in Singapore. Magic!

    Absolutely fantastic piece of kit to have on your yacht. Very user friendly.
