Angelo Lavranos designed the L26 in 1978, which went on to become the leading competitive keelboat class in South Africa. Below is Angelos own account of how it came about, so Ill leave that to him. Angelo was a South African (as far as I know - he certainly lived here for many years), before moving on to New Zealand where he now lives. L26s were all built in SA, originally by PSI Yachts in Durban, later by Ton Cup as well. Maybe others too. Despite its age now (30 years) - the "Ls" as they have become known are suprisingly fast - even beating some of our larger racers across the line on occasion! They are particularly fast upwind if they have enough crew and benefit from the relatively high crew-weight/displacement ratio, sitting out on the wide beam. They have a high form stability factor, being beamy and light, but generally low-tech boats, keeping costs down. Despite this, Ls manage very well in heavy weather. Mostly, they have no reefing points in the main - at least in the racing suite! They remain a well managed class, and the class choice for the Lipton Cup. They are now relatively affordable and have made performance sailing accessible to many of the youth and development programmes in SA. Lavranos also desgned many other successful boats (too many to mention!) - see his website at www.lavranosyachtdesign.co.nz

Notes on the L26 by Angelo Lavranos
5th May, 2007

Back in 1978 I was asked by David Cox to design what became the L26. Dave was one of Durban’s most prominent and influential “movers & shakers” in yachting. He later also initiated and masterminded the L34 Class also. Dave felt that “one Design” was the way to go, and that a large body of yachtsmen were fed up with “chequebook“ yachting and rapid obsolescence endemic with the IOR rule of that time. That sounds a familiar complaint even now. How right they were ! Dave and John Gordon Thompson formed L Boats as the licensee. The first boat afloat “Electron” (small but very very fast!) owned by Johnny went afloat in April 1980. Actually No 001 was for John Sully (a very prominent Transvaal Yachtsman) who was the first “real” buyer. Within 12 months there were 12 afloat, all from PSI Yachts in Durban, and 32 on order. By 1981 Ton Cup Yachts in Cape Town were also licensed to build. By April ’82, 60 were built with another 10 on order. Dave wrote an excellent set of Class Rules right at the outset, and marketed the boat very effectively and relentlessly. Ultimately (within very few years) 84 were built.
When the L26 was conceived the Lipton Cup was “dormant” since the demise of the 30 sqm class. In 1982 it was revived using IOR Quarter Ton Cup Class boats. Within a couple of years that too fizzled. The L26 was chosen only in 1984, when the class was already established and very well distributed amongst all the clubs round the country. Because of this the Lipton Cup was an instant success in the L26 and the event in turn helped maintain interest in the L26.
The design brief given to me was the key to the success of the boat.
1.Simplicity. This essential element of this is the runnerless, swept single spreader rig, robust enough for long life, handling mistakes etc. The IOR rigs of the time used runners, were delicate and obligingly fell down if misused. This was No-No number 1.
2.Rugged, designed to last, no breakages. At Dave’s insistence we stuck to a solid glass structure which is heavier than a sandwich. Dave was worried about ongoing supply of core material as well as the increased cost, consumer resitance etc. By the time the L34 came along he relented on this but in 1978 he probably made the right decision.
3.The boat should be able to handle SA coastal conditions (something most One Designs and sportboats of similar length, especially the lighter more recent ones are less able to do). Because of the L26’s waterplane characteristics and topside configuration she is able to take a person ahead of the mast while doing spinnaker gybes etc in strong winds without broaching or nosediving. The boat handles sweetly through the whole windrange, both upwind and down. When overpressed the helm just gets a little soggy, making her one of the more forgiving and docile boats to sail.
4.She had to be fast and fun to sail. In 2007 she might not bring the same excitement to Adrenalin junkies, but across the board for young and old she strikes a good balance.
5.Moderate cost, a “no frills boat”.
6.Tight Class rules.
7.Capable of “overnight” coastal races and weekending
She fulfilled the brief OK. Many have done coastal passages, and even the Da Gama race from Durban to East London (and back) several times. In the terminal “horror” Da Gama race of ’84 Dick Haliberton in Element was OK but Cape of Good Hope the Navy entry did a 360 roll, and somebody opened the hatch in the process. They flooded and got rescued. Notably Steve Meek even sailed one from Cape Town to East London, doing a 194 mile day in the process.
I designed some “spin off” boats for Dave Cox after the L26’s stopped. We did one with the L26 hull and a cruising deck (more headroom, volume), a shallower keel, cantilever mast called the C26. With the economic recession only two were built. After that another 2 or 3 were built with conventional stayed rig and called the S26. Also the original C-Flex plug with a wood deck using the L26 design (sail no 000) called Origin also did a lot of racing (outside the L26 class.)
The sailors and people involved in the L26 have been a vertiable “whose who” of top Yachties, ALL the sailmakers (most notably Rick Nankin in partnership with Chris King), and a lot of very successful people in other spheres. Lex Raas, who built all the Cape boats is now CEO of Moorings worldwide. His partner in Ton Cup was none other than John Robertson. His (late) partner Jerry Caine built a lot of the Durban boats after Basil Cook at PSI Yachts.
