Why Quantum Sails?

Mark Mansfield, four-time Olympian, professional sailor/coach and J Boats and Grand Soleil agent for Ireland, outlines why he has decided to link up as an agent for Quantum Sails.

I was recently appointed the Irish agent for J Boats and Grand Soleil Yachts in Ireland so adding a sailmaker agency to my armoury was a natural addition. I looked at various options and in the end, I went with Quantum because:



I am a little biased, in that I chose Quantum sails in three of my four Olympic campaigns, but these were Dacron one-design sails. Quantum has also been one of the major big boat sailmakers for many years.

Their Top range Fusion Technology can be seen in such boats as:

  • Quantum TP 52—Consistently the top Tp 52 in the Ultra competitive TP52 circuit.
  • American Magic—Foiling US Americas Cup Challenger from the New York Yacht Club 
  • Swan 36—Chose Quantum to design the first sails for this new exciting class, as did the Dehler 30 one-design class.

They all use Fusion MR Technology product, which are membrane sails designed and built specifically for a particular boat. This product can be had with, Carbon Strengthening Threads—Fusion 7000 series—generally used at the top racing level and needed for boats over about 33 feet to keep the sails from stretching.

Aramid (Kevlar) Strengthening Threads—Fusion 5000 series—Generally used at a top level for racing and needed for boats between about 28 to 33 feet to keep the sails from Stretching.

We then also have our Tri Radial product, which uses laminated sailcloth with various Strengths (some Carbon, some Aramid, some Polyester), constructed in load-bearing tri-radial designs. These sails are perfect for the club racing level sailor, who wants a quality product, which will last, at a more affordable price level.


I priced sails with other sailmaking brands in the 30 foot, 35 foot and 40-foot range and consistently Quantum came out the most competitive for both their Top range Grand Prix Fusion MR products and also their Step down Club racing sails.

I believe in Ireland Owners are generally unhappy about the high pricing levels for sails, which have seemed to increase right through the recession at a level not seen in any other products.

Clients should remember if they are getting quotes for sails, that the quotes they receive have the same base structural strengthening material (Carbon/Aramid/Polyester) as the other sailmaker. Just because a sail has a fancy badge, has a fancy brand name and is black, that doesn’t mean it is the correct sail for the boat and is strong enough. Often sailmakers, especially if they are in competition with another sailmaker, will quote on a sail that looks fancy, but the internal load-bearing material (maybe Polyester instead of Carbon) is not going to stop stretch and so will have a much shorter competitive life.

This is always important and Yannick Lemonnier has been servicing sails in his Galway Loft for over 10 years. Yannick was the Quantum Sails Agent for a number of years and is now back into the Quantum family. Yannick has a 250 Sq. metre Loft with three Machines, which can repair and recut any size sail. They can also manufacture Covers and other canvas products like Dodgers, Biminis etc.

Yannick will cover the West Of Ireland, I will be covering the South and between us, we will cover the East, Midlands and Northern Ireland. Should a client go with us, he will get significant backup, which will include rig tuning and other go-fast requirements.

Ireland now has another proper option for the purchasing of sails, with the arrival of this World Class Quantum brand to Ireland. Come and ask Yannick or me for a quote. You won't be disappointed.
