You're looking at the photos of the first set of riblets, made from thin ABS sheet. These soon failed, due to UV attack, and in any case the edges...
The answer is very, very simple! I shall use a chinese sheet! And it will be as effective as I choose it to be! To learn more, buy a copy of...
groper, What am I trying to achieve? You’re kind of right with both your 1) and your 2) - I worked as a designer, and I can’t stop designing and...
Well, for the over 80,000 miles sailed thus far. CE marked in Category A, ocean. You'd have to join the JRA at www.junkrigassociation.org, only £7...
Merci beaucoup pour l'opportunité de le voir! Les similarités sont expliqué! Some things I noticed: 1. Conventional slab reefing, with 5 reefs....
Principally - it doesn't employ chinese sheeting, which looks after the reefing as well as the sheeting angle. It has a rotating mast, and with...
You're having some interesting ideas, Will. You may not be aware of the work of a fellow JRA member, Paul McKay (pic attached). Please go on with...
I came across Matin Bleu in Polynesia in 2007, and had a look at the rig. It was quite similar to the one that Beneteau's designers are working...
Also, in the Hauraki Gulf, there's Cool Change, a larger cat with a similar biplane rig. That's probably as far as you need to go with a large...
Only off-topic insofar as hard wings are mentioned, but everything else might apply to soft wings for cruising, so: There are now several...
I think you're missing the point, Fred. I just read Casino Royale (1953) again. Bond is driving a 4 1/2 litre Bentley (25 HP is quoted, but surely...
Have a look at : http://www.yacht.de/service/heft_info/innovativ-der-fluegel-fuer-alle/a86617.html It appears that Group Beneteau is about to...
" ... but the performance is better than a pure junk rig. ... I'd rather like to go back to this rig, as it was actually even easier to handle...
A sail on an unstayed mast can be sheeted out past abeam, yes, but then the steering gets very peculiar, with unexpected lee helm at times, and a...
There's plenty of evidence, both theory and practical, that a low quadrilateral sail (square sail, lug sail, gaff sail, junk sail) is both more...
Maybe you're thinking of the UK 6ft 10in wide (!) narrowboat, where you have to go well above 40ft to get enough accommodation. A barge is wider,...
George, I'm living (6 years half time, 7 years full time) on a cruising sail boat 35ft x 11ft, and have all the room I need for one, and enough...
Well, yes, for a race boat it's of prime importance. That's why we see deck-sweeping genoas. But for a cruiser, 360 visibility and ease of...
This is in fact what I am doing. My previous wing sail ketch rig had too much area in the mizzen, and the helm was badly balanced. The first reefs...
There have been a number of rigs built with symmetrical wings, either soft or hard, over the years. I can think of some of my early attempts,...
