Introduction – Specs and About The Laser Dinghy
The Laser was designed by Bruce Kirby and unveiled to the public at the 1971 New York Boat Show. Since then 200,000+ Lasers have been built to date and are sailed across 140+ countries, with its popularity being primarily due to its simplicity and performance.
Racing is very competitive due to the one-design restrictions, which means sailors are truly able to test their ability, rather than rely on differences in hull shape, sails, and other gear to gain an advantage.
Rigging is easy using a sleeved sail over a mast with no stays, and can be launched and sailed single-handedly with ease. Minimal parts mean minimal breakages and maintenance.
The Laser Dinghy – 3 Sailboats In 1
The 3 rigs – 4.7 / ILCA 4, Radial / ILCA 6, and Full/Standard / ILCA 7 Rigs – mean that sailors of just about any ability or age can enter the sport, and advance with minimal cost.
The Laser 4.7 / ILCA 4…
utilizes a smaller sail than the Standard rig (4.7m2 / 50.6 ft2 which is 33% smaller) and a shorter pre-bent lower mast section. It is ideal for lighter sailors (up to 121lb / 55kg) and beginners.
The Laser Radial / ILCA 6…
uses a smaller sail than the Standard rig (5.76m2 / 62 ft2 which is 18% smaller) and a shorter more flexible lower mast section. It is suitable for sailors between about 121lb – 154lb / 55kg – 70kg. The Radial is the most popular class of Laser, as it is suitable for the largest amount of people, including youth, women, and masters. The radial sail can easily be identified by the sail cut in a radial pattern emanating out from the clew.
The Laser Standard / ILCA 7…
has a 7.06m2 / 76 ft2 sail, and is more suitable for sailors above about 143lb / 65kg. This rig is suited to the heavier sailors in windy conditions where weight, strength, and fitness are critical.

Hi,
I am switching my boat from sailing 470 to sailing a laser now. I intend to sail laser primarily to qualify for the Olympics.
My question is if my height is good enough to sail laser standard. My height is 167 cm (5 ft, 6 inches) and weight is 68kgs.
Thanks,
Vincent
Hi Vincent. Thanks for your question.
I would say that at 167 cm and 68kgs, you would be at the lighter/shorter end of the scale for sailing a full rig laser. You may be able to put on some bulk before the next Olympics to handle it a bit easier.
I think everyone has different opinions on what is the ideal weight for a laser. A lot depends on the conditions and your skill.
Have a look at Australia’s gold medalist at the 2012 London Olympics Tom Slingsby’s vital stats here. He was 83kg & 186cm at the time.
Good luck with it, and all the best.
Brendan
My Grand daughter would like to switch froom sail Terra to Laser. What is the minimum height for the class
Hi Norman
Thanks for your question.
I’m not sure that there is a minimum height. It’s more about the weight. For a Laser 4.7, the ideal weight is around 110-130 lbs (50-58 kg). Any lighter and she may have trouble keeping it flat in a breeze.
cheers
Brendan
Hi,
I am looking to buy a laser and am 5ft 10 (178cm) and around 68kg, I sail in a harbour so short chop is the worst condition, do you think I’m big enough for a standard?
Hi Giles
I don’t think it’s as much about the height as it is the weight. At 68kg, you might be a little on the light side for a full rig. But it depends on how windy it tends to get also. If it’s generally pretty windy, you might struggle, but if it’s often fairly light, you may be ok.
This thread has a good discussion on the ideal weight for laser standard sailor.
Hope that helps.

Hi
My sea scout troop has taken possession of a Laser 2. It lacks a suit of sails and a rudder. talking to others, no one is sure if the rudders are identical to Laser 1’s. Can you advise?
Hi Pete
Thanks for your question.
I am not very familiar with the Laser 2, so did some research. However, it was very hard to come up with information on the Laser 2 specs.
From what I could tell, the rudders are different between the Laser & Laser 2, however, I was not able to find the actual specs on the Laser 2 rudder.
For a measurement diagram for the Laser rudder, click here (click on the “Mast Top Section, Boom and Foils” tab).
For an image of the Laser II rudder, check this out.
As you can see, it looks slightly different to that of the standard Laser rudder.
Sorry I can’t be of more help than that. Maybe some other readers can provide some more info.
cheers
Brendan
Hello,
I am 6 feet tall and weigh 53 pounds, what laser whould be good for me?
Hi Alessandro
Thanks for your question. I hope you mean 153lb, and not 53lb!!
Opinions vary, and it depends on your fitness and ability. If you are just starting out, you may be best suited to a Radial Laser, but you are in the overlap zone between the Radial and Full rigs. So it depends a lot on your experience and fitness.
It can also depend on where you live. If it tends to be quite windy on a regular basis, then you may opt for a smaller rig. Conversely, if it’s often quieter on the water, then a bigger rig may help.
I’m a few lb/kg heavier than you, and I have a full-size / standard Laser rig. I find it’s great for the lighter days, but can be a bit overpowered on the heavier days. I don’t mind though, as it just makes it more exciting when you go around the top mark.
cheers
Brendan
Hi I’ve just brought a laser with a radial sail but a Standard mast. I was gonna make a Radial mast out of the right alloy tube but I need the measurements. Would anyone know what is The length of a radial mast?
Thanks
Kaleb
Hi Kaleb
Here are the measurements for the different Laser masts for each of the top and bottom sections.
cheers
