Simple | Minimal

Superior Handling


The JS designs: JS-4300, JS-4600, JS-4700, JS-4800 and JS-4900 represent a body of work (design, evaluation and engineering) that has been carried out over the past 5 years. All designs contain the same “core values” of the famous Laser – “minimalism and simple”.

The JS Yachts range is designed in that every boat can be tailored to an individual skill level by way of sail plan selection. Laser replica sail and spar configuration are interchangeable with JS Yachts design proprietary set up.

Sailor's Comments

They’re great boats, they are very easy. You don’t have to be an incredible sailor to put them together and to get out there and go. And, if you are a high-performing sailor, the boats can also perform to that standard. They’re versatile and they cater for a wide range which is really good, and they’re definitely fun boats to sail.

They’re great boats for development and progression – that is an adult, or whoever, could progress right up to high level racing with these boats by just changing the sails. They are really inexpensive to be able to progress with because you just need to buy other (bigger) sails and not another boat.
They’re a great progressive boat. They’re a stable boat, great for learning in. They are so well set-up they take care of themselves, nice and steady. They’re quick to put together which is really great.
I think the JS 4.3 is a very attractive boat. It is comfortable as well as maneoueverable. I love how fast it is and how much fun!
