New Hull Mould for 2018
At Mackay Boats we are always looking for ways to improve the performance of the 470.
Over the past couple of years sailors have been telling us that they want a boat that is easy to sail now that they are using so much energy body pumping.
We got Nathan Wilmot and Jo Aleh to sit down with our Naval Architect to review how 470 sailing had changed over recent years and how we could make a better boat for Enoshima 2020.
The new mould is closer to our very sucessful 2000's design that won so many regattas during that period.
To do this we added a little bouyancy in the back of the boat which will make it easier to steer in waves and easier to catch small waves downwind. There is also a little bouyancy added in the front to balance the changes in the stern.
The changes are hard to see, but we know how 470 sailors are able to feel the smallest of changes and turn them into winning results.
The first boats from the new mould will be sailing Auckland in November 2017 and competing in Miami 2018.
The obvious advantages are that the boat will hold high rig tension and not flex in the bow and mid sections. A significant underlying advantage is that the tune of the boat will not change through a season of racing. It will not go soft (as some boats do) and therefore the rig tensions and mast bends will not alter as the season progresses. The construction techniques we use give greater longevity and therefore eliminate the need to replace the boat every year or two. A good crew can develop the tune of the boat and know that they can keep it for several seasons.
We believe that our construction techniques are as advanced as allowed by the rules. The building process also involves a considerable amount of custom workmanship. All of the ribs on our boats are vacuum clamped foam with chopped mat and uni-directional rovings on top. We obtain extra strength from the rigidity of the foam itself. It is important to realise that we do not "mass produce" the Mackay 470. We concentrate on building fewer boats but of a very high quality. We have placed the greatest importance on workmanship, with care and attention to detail.
International 470 Class History
In 1963, French architect Andre Cornu designed the two-handed centerboard boat as a modern high performance fiberglass planing dinghy which could be sailed by anyone. And the craft so influenced European sailing that the 470 is directly credited with drawing new sailors to the sport during the 1960s and '70s.
An Olympic class boat since 1976, 470s are sailed today for both family recreation and superior competition by more than 30,000 sailors in 42 countries worldwide. The 470 is so popular that its annual World Cup event is considered one of sailing's major international regattas attended by sailors and spectators from around the world.
A light and narrow boat (length 4.7m and beam 1.7m with a weight of 120kg), the 470 responds easily and immediately to body movement. Thus, the sailors' teamwork and tactics complement one another. The skipper is smaller and lighter (1.65m to 1.8m and 55kg to 65kg), and the crew is tall and light (1.75m to 1.85m yet only 65kg -75kg). The crew's build lets him or her hang far out on the trapeze to keep the boat level in all conditions.
In 1988, women officially entered Olympic sailing competition with the first-ever 470 Women's event. This boat is especially well-suited to women's competition because of its light weight, maneuverability and light crew weight requirement.
