Laser Dinghy Background
The Laser Dinghy, a one-design racing sailboat, 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 their popularity being primarily due to their simplicity and performance.
The original concept for the Laser centered on creating a boat that was easy to build, sail, and purchase, thereby making it accessible to a broad range of sailors. The Laser quickly gained popularity and became the boat of choice for many sailing schools and clubs worldwide. It also rapidly gained recognition as a racing boat and debuted as the single-handed open-class dinghy in the 1996 Olympic Games.
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.
Besides being used for competition, the Laser is a popular choice for recreational sailing. You can spot these dinghies on lakes, rivers, and oceans worldwide. With its one-design nature, ease of use, and practicality, the Laser Dinghy is set to remain a popular sailboat for many years to come.
The Laser Dinghy – 3 Sailboats In 1
The laser dinghy comes in 3 rig sizes:
- 4.7 / ILCA 4
- Radial / ILCA 6, and
- Full/Standard / ILCA 7 rig
This means that sailors of just about any ability or age can enter the sport and advance with minimal cost.
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 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 number 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 heavier sailors in windy conditions where weight, strength, and fitness are critical.
The International Laser Class Association
The International Laser Class Association (ILCA), a global organization with regional sites, governs the Laser class of sailboats. The organization is responsible for developing and enforcing the class rules, which ensure that all Laser boats are built to the same specifications and are eligible to compete in official Laser regattas. The Laser Class Association also organizes and oversees major regattas and championships, including the Laser World Championships and the Laser Masters World Championships.
Membership in the Laser Class Association is open to anyone who owns or sails a Laser boat. Members have access to a wide range of benefits, including access to official class materials and publications, as well as opportunities to compete in official Laser events. The Laser Class Association also offers support and guidance for sailors who are interested in organizing their own Laser regattas.
The Laser Class Association plays a vital role in promoting and supporting the Laser class of sailboats and is a great resource for anyone who is interested in Laser sailing.

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.
Just for your info, I did some research on stats for Australia’s gold medalist at the 2012 London Olympics Tom Slingsby. He was reported to be 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.
Brendan
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.
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

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
How tall is the mast on the “std” Laser? I had one once and it was fun getting it into the hole on the hull!
Cliff
Hi Cliff
Yes, it can take a bit of getting used to, when putting the mast into the mast step.
Looking at this site, the total laser mast length should be approx.:
– top section (including top plug) = 3600 – 305 = 3295mm
– bottom section (including base plug) = 2865mm
Overall laser standard mast length = 6160mm / 20.2 ft (approx.)
Hope that helps!
Hi,
I am 155 cm tall and weigh 49 kg. Am I suitable for sailing a laser 4.7 or should I sail a 420?
Hi D
I’m not an expert with the 420. For a laser 4.7, I think you would be a bit on the light side, but it also depends on how fit, strong, and experienced in sailing you are. It may also depend, to some extent, on where you live (some places are windier than others)… if you have a strong sea breeze every afternoon, then this may be too much.
Hi,
I’m a fairly experienced optimist sailor and I need to change my class due to my age. I am 157 cm tall and I weigh 46 kg. Would I be able sail a laser 4.7? The place I live can get very windy at times.
Thank you
Hi Defne
I think a 4.7 should be ok, but it would depend on your experience and level of fitness. Since you say that you are a fairly experienced optimist sailor, then that will definitely help. You might struggle a bit on the windy days though.
If you can, ask around your local club and try to take a 4.7 out for a spin. Let us know how you go!
All the best.
Hi I sail optimists and are looking into a laser as the next boat. I weigh 122 pounds and was wondering if I should get a radial or a 4.7 rig
Hi Noah
Your situation is similar to the previous comment in June, so not sure if you saw that.
It depends on a few things… including how experienced you are, how fit and strong you are, and what the typical conditions are like where you sail.
At your current weight, you’re probably at the lower end of the ideal weight range for a radial. But if you are young and still growing, you might want to get the radial and grow into it over the next year or so. But you might struggle a bit at 1st on the windy days.
See if you can take one of each out for a spin and give it a test for yourself.
Best of luck with it!
Hello I have a Laser Radial sail with a “33” number above the boat sumber.
the boat number is 177137 so its not an abbreviation of that …
do you know what the 33 means? Thanks!
Hi Russ
I’m not sure what the “33” about the boat number would refer to. Maybe some other readers may be able to help?
Sorry I can’t help more than that. All the best with it.
Hi.
I am currently building an El Toro dinghy. I do not want to have to handle the full 14 foot one-piece mast. I read somewhere that you can retrofit a laser 4.7 mast and sail onto an El Toro hull. A Sabot boom is marginally cheaper than a laser 4.7 one, and I was wondering if a laser 4.7 mainsail would fit a sabot boom.
Thanks!
Hi Alexander
I am not an expert on sabots, but from my research…
The Laser 4.7 sail has a foot of 2.48m / 8.1ft.
The sabot sail has a foot of 7ft and a boom of 7′ 3″.
So the sabot boom looks too short for a Laser 4.7 sail.
Can anyone please tell me in what year Laser #66750 would have been made?
Hello Steve
According to research that I had done previously, it looks like sail number 66750 would have been made in 1979. See this link for more info.

Hi,
I have sailed Sunfish sailboats, and years ago I crewed for a friend on his J24 in PHRF races. I love the idea of excitement when I sail, but I would also like to be able I sail with a passenger. Can a Laser be sailed with a passenger for entertainment? I did not see anything about the maximum capacity of the hull.
Doug
Hello Doug
A Laser sailing dinghy is designed as a single-handed boat, meaning it is typically meant to be sailed by one person. However, it is possible to sail a Laser dinghy with two people, although it may not be the most efficient or optimal way to use the boat.
It is only a small dinghy, so the extra weight will affect the performance. There is not much room in the cockpit for 1 person, so for 2 people, it will be even more cramped.
If you just want to go out and have some fun (and you and your passenger aren’t too big), then you can probably do that. But there are many other dinghies available that are specifically designed for two-person sailing that would be a better option.
Hello,
I am looking for the width of the bottom part of the mast, to design a fitting for a wind indicator. Although I have looked through many sites (including the ones linked in the comments), I can’t find the specific measurements.
James
Hello James
The Laser mast diameter is approx. 2.5″ or 64mm.
I holiday in Finland and have just been given a laser to use but I need a hand trolley to get it over the stones on the shore. When I had a laser before many years ago, I had a light hand trolley made with plastic tubing. Do you or anyone else have a model on how to make one? I have wheels
Hello Brian
I do not have any plans or instructions, but there are a few forums that discuss how to make a homemade dolly. Check out some examples here and here.
Otherwise, there are new dollies for sale. Have a look at this page for more info.

Hello,
I’m from Brazil, and wind conditions here in Florianopolis where I live exceeds 15 knots easily.
I sailed laser for several years, stopped some time ago and want to return. I am currently 59 years old, weigh 183 lb (83 kg) and I am 5’8 (1.74m) tall, being in good physical shape and codition. The question is: which laser rig would be suitable for competing, ILCA 7 or 6?
Thanks!
Hello Estevao
Thanks for your question. Since you have sailed a Laser dinghy before, you know how hard on the body they can be… especially on the thighs, abdominals, arms and back. If you are fit and strong, particularly in those areas, then in my opinion, you may be fine with an ILCA 7. But an ILCA 6 might be more manageable for you.
