The 420 is one of the best options to learn the ropes about two-person dinghy sailing. Crews learn how to tune a boat, set up control systems, trim sail combinations (jib, main and spinnaker together), work on downwind and upwind techniques, and importantly, learn how to work with another crew.
The Class has attracted many top sailors to it, providing a learning platform that has led them into successful Olympic campaigns and big boat careers.
The 420’s design and class rules gave us the opportunity to build a boat similar to how the Mackay 470 is built in terms of the mould structure and look of the boat.
The Mackay 420 hull shape was developed by naval architect Kevin Trotter. Kevin has designed very fast dinghies here in New Zealand over the years. Using the latest design and analysis software, along with the luxury of time we were able to evaluate the expected performance along with the look of the boat.
Looking at where crews tended to sit in the boat in different conditions affected where we pushed the displacement curve of the boat. Additionally, Kevin's skiff designs gave valuable insight into the way the rocker curve and buttocks lines should run through the middle and aft sections.
The hull is made from a polyester e-glass fibre, using foam core ribs and core mat panels.
The Mackay 420 deck to hull joint system is the same as our 470s, which allows for the same exceptionally strong but light gunwale arrangement. This extends around the bow and across the transom.
We have also borrowed some other features off the 470. As an example, the way the mast partner is fitted to the deck after the boat is built allows the bulkhead in front of the mast to be more vertical and closer to the mast. This is better for rig tension and weight distribution. It also improves the look of the boat giving it a longer foredeck.
The rudder stock is in cast aluminum which provides excellent support. The foils are built in the same way as our 470 foils by resin infusion.
Most importantly the time and energy we put into the rudder and centreboard design along with the finishing of the moulds has resulted in some very special foils.

How to do a gelcoat repair.
Small gel coat repairs are relatively easy to do.
What is Gelcoat made up of?
Gelcoat is a polyester product that is cured by using a catalyst called MEKP. (Methyl Ethyl Ketone Peroxide)
MEKP is a dangerous substance and should be treated as such when using, being very careful not to get any on your skin or in your eyes.
How can I get the catalyst - MERK?
We cannot ship MEKP so you will always need to buy it separately from your local marine store or fibreglass manufacturer.
How much MERK do I need?
The amount of Catalyst varies depending on the conditions you are using it in, but around 2%-3% will always work.
It is best to use a small syringe or dropper to get the required catalyst rate.
If you have mixed 100gm of gelcoat, then you are aiming for 2ml of catalyst.
What are the Gelcoat colours?
Gelcoats colours are not always a 100% perfect match.
Colour will vary depending on the depth of the repair and the batch.
470, 420, 29er & Starling are built from polyester resin.
For Polyester boats
470 White- LS30 White PA 337
470 Grey- Grey RAL 7035
Blue = is supplier by Nuplex who have their own code which is not an international code
Does Mackay Boats supply gelcoat?
We supply a small tin (of each relevant colour) with each new boat.
Order additional gelcoat from our store, although it cannot be shipped by courier.
How do I do gelcoat repairs?
Doing gelcoat repairs is an art that improves with experience.
Making sure the surface is prepared well and keyed up is critical.
Overfill and then sanding back is a slow and time-consuming process.
Be very careful not to scratch the boat around the repair.
You shouldn’t sand the original surface around the repair with any paper coarser than 600grit.
Mask around the repair to protect the boat.
You can initially use a file or 150g to take the high parts off the filling, but don't use the coarse paper for too long or you will end up with scratches in the finished repair.
Once you have it fair with 600g, you can work your way through the sandpaper grades until you finish with 1500grit before cutting and polishing.
We would typically use 600g, then 800g or 1000g, then 1200g, then finally 1500g.
What can be customised?
Deck colour and non-skid on the side-decks. You can find these options if you try the boat configurator on our website.
What colour options do you offer?
White, Light Grey, Light Blue, Light Green, and Cream. On the 420, Grey is the most popular, with Blue and White equal second most popular.
How do you fit a mylar gasket the hull?

Information
Characteristics.
The 420 is the most popular double-dinghy in the world. Designed in 1961, about 60,000 boats have been built in all these years. In Spain, the class is at a great moment. The Cup and Championship of Spain hover around 100 participants each year, there are regattas with lots of participation in all the communities and titles and international recognition is constant.
Lenam Vela Ligera, licensed for manufacture since 1998 has contributed with more than 1300 boats to the 420 class. At Lenam we make a 420 without haste, with passion. The whole process is studied in detail.
The 420 has a strict regulation regarding the materials to be used in its manufacture. Only polyester resin is allowed, while Sandwich-type construction, which is allowed on Optimist, Europa, Snipe…, is forbidden. From these premises, the quality of the raw materials used in the construction of the 420 Lenam is maximum. The NPG isophthalic gelcoat and the isophthalic polyester resin, both with the highest H.D.T (temperature at which the gelcoat and resin can degrade), allow an elongation and elasticity of the laminated materials unequalled, enduring the harshest sailing conditions and suffering less with collisions than other boats.
The glass fibre used is the mat with powder binder, which avoids osmosis problems and offers better chemical resistance properties than other fibres of lower cost.
These materials are much more expensive than other permitted materials, but they ensure an unsurpassed quality of finish and a longer life and competitiveness of the boat over time.
It has already been mentioned mentioned that solutions to give rigidity to the hull or sandwich-type deck with P.V.C. foam are not allowed in 420. What is allowed to give consistency to the hull and deck are omega-type reinforcements to be placed according to the criteria of the shipyard. And it is at this point where the 420 Lenam has an important number of original reinforcements, which perfectly combine its minimum weight and maximum rigidity. In addition, the 420 in general for its special shape with a bulky bow, must take special care to make it light in that area, which Lenam achieves with a particular design of omegas in bow, very light and consistent, which at the same time allow it to provide the hull with a center of gravity more backward than its competitors, a fundamental aspect in short wave conditions or with weighty crews.
Once the hull and deck have been laminated, they remain in the mould for a minimum of one week, in a post-curing process at a constant temperature, in order to achieve the necessary degree of rigidity and curing that will provide the definitive dinghy with a long life at full performance.
And if the materials to be used are very limited, as we have commented in the 420 rules, on the other hand the water lines of the class allow tolerances that give a lot of game. Lenam gives a very versatile response to all wind and wave conditions. The wave conditions can be very different depending on where you are sailing. For instance, the typicall Mediterranean wave, characterized for being short, is different than the waves you can find in the Atlantic. Because of the knowledge provided by sailors and monitors, the water lines of the Lenam give a very easy navigation and maximum speed in these so diverse conditions.
The position and draft of the centreboard and rudder have also been studied to optimise navigation.
The design of the deck, the only one of all the shipyards manufacturing the 420 that is in one piece, contributes to the perfect alignment of the key elements in this section, such as stay chain, bonfire, cockpit, centreboard box and rudder hardware.
The boat is presented with the best hardware and accessories, with the cockpit as “clean” and tidy as possible. Details such as the padded belts with no water absorption, the neoprene anti-slip system for the crew, the spi bags made of water- and sun-repellent fabric… everything to give the sailor the peace of mind of knowing that he is sailing in a boat in which everything is designed to give maximum speed and comfort to the 420!
Elias Aretz, together with Pablo Garcia, runners-up of the world and Spain 2018
“We have been fortunate to be part of the Lenam team in recent years, getting material that has allowed us to fight at the highest level in this class. It’s a boat that adapts very well to all conditions. The quality of the materials used and the personal dedication behind each boat manufactured, is noticeable in the finish and over time. Added to this is the constant research always looking for the most innovative technologies of the moment to continue being one of the most competitive boats on the market”.
Wichy Hernandez, together with Nacho Balaguer, champions of Spain and fourth of the world 2018
“I have had a long ride in the 420 class, about 8 years uninterrupted in active sailing. From 2016 until now I have sailed with Lenam and in the last two years there has been a great evolution to reach the current boat. Manel has managed to make a very competitive boat, you only have to look at the results obtained that endorse it in recent years. Its volume in the bow gives us a boat much more stable than the rest and, in wavy conditions, it gives us a lot of comfort and ease to pass the wave. With low wind conditions it is one of the fastest boats in the market. The new Lenam Race One is harder than its predecessor, the Lenam Gold. The internal construction has been changed and the result is a very fast boat with wind conditions and also it has more durability. Without a doubt, it is the best quality-to-price ratio 420 you can find. We have the best at home!”
New lighter, softer and more aesthetic kicker and main sail cuningham controls.
New control system of the spi sheet with the barber hook to the maximum in front of the chain allowed.
Simple and effective transom window system with “suction” effect.
New padded belts with no water absorption adjustable thanks to the dynema rope
New material in anti-slip neoprene for the crew member. Perfect grip of the foot and soft to the touch that does not tear the water suits.
New transom bead, which provides greater strength and helps to avoid the annoying collisions typical of regatta starts.
Large opening in front of the daggerboard box that helps to drain the water in the direction of the bayler.
Large opening behind the daggerboard box that helps the perfect drainage of the water in the direction of the bayler.
Simple and hidden centreboard lowering system.
Large bags of anti-solar fabric and Teflon finish, water repellent, with diagonal openings that facilitate the lifting and lowering of the spinaker. Transparent window in starboard bag for “instructions”.

420 is a 13 ′ 9 ″ / 4.2 m monohull sailboat designed by Christian Maury and built by Rondar Raceboats, Fountaine Pajot, Snapir Sailing Craft Ltd., MacKay Boats Ltd., Lanaverre, Johnson Boat Works, Far East Boat Co., Whitecap Composites, Xtreme Sailing Products, and Nautivela starting in 1959.
Rig and Sails
Auxilary power, accomodations, calculations.
The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.
Classic hull speed formula:
Hull Speed = 1.34 x √LWL
Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL
Sail Area / Displacement Ratio
A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.
SA/D = SA ÷ (D ÷ 64) 2/3
- SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
- D : Displacement in pounds.
Ballast / Displacement Ratio
A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.
Ballast / Displacement * 100
Displacement / Length Ratio
A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.
D/L = (D ÷ 2240) ÷ (0.01 x LWL)³
- D: Displacement of the boat in pounds.
- LWL: Waterline length in feet
Comfort Ratio
This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.
Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )
- D: Displacement of the boat in pounds
- LOA: Length overall in feet
- Beam: Width of boat at the widest point in feet
Capsize Screening Formula
This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.
CSV = Beam ÷ ³√(D / 64)
One of the most successful sailing dinghies ever. (Only the SUNFISH or LASER can be considered in the same league.) Originally designed and built by Lanaverre of France. (They built 32,000 according to one source.) Licenses were later granted to other builders around the world. In 1996, the International Class agreed to amend the deck layout. 1 Trapeze permitted. Spinnaker: 97 sq.ft. There is a ‘Club’ version of heavier construction and slightly different dimensions.
