“7”,”851283″,”9″,”Re; Re; Surface piercing hydrofo||851283″,”Jake,

The foiler moths that I have seen don’t have fences fitted and seem to be able to get away without them. In the first instance, in your position, I wouldn’t bother to fit fences and just test the board to see how it goes. After experimenting, if you have the feeling that air is being drawn down on the low pressure face, then you can always retrofit a fence or two later. Any fence will normally add drag, and that is the last thing you need if you are trying to speed sail. “,”2005-06-26″,”Martin Grimm”,”nopswd”,” “,”seaflite@alphalink.com.au”,”0″

“9”,”821336″,”9″,”Re; Re; Surface piercing hydrofo||821336″,”Thanks Tom,
I have just re-read my posting and I have been somewhat confusing. I am not looking at bi-directional foils. I am wishing to build a pair of asymetric windsurfer fins suitable for surface piercing usage, as the fin will be fitted behind or to the side of the board, not sticking out of the bottom of it, and may be canted to provide some lift. As I have fitted the device to a speed board and intend to take it to Weymouth speed week this year, low drag and no ventillation at high speeds are important factors. I have also conceived a system that enables the two separate fins, one port , one starboard profiled to be swapped while sailing. I just need to get the test rig working on one tack so that the optimum fin position, cant, rake, attack angle etc. can be discovered.
Could I just use one of the profiles you recommend for foiler moth lift foils and fit a couple of fences?
Rich Miller, by using a long symetrical root foil with fence, ended up with his asymetric foils submerged all the time, so the demands on his foils were slightly different to mine. “,”2005-04-30″,”Jake Frith”,”nopswd”,” “,”jakefr@southamptonrowing.org”,”0″

“10”,”821326″,”9″,”Re; Re; Surface piercing hydrofoil||821326″,”I don’t think ogival sections are a great idea. The sharp leading edge leads to separation unless the angle of attack is in a narrow range of ideal angles of attack. When separation occurs, you have all the ideal conditions for ventilation. So everything can be fine, and then suddenly change dramatically with just a small difference in loading.

It’s possible to design bi-directional sections that have rounded edges instead of sharp ones. With attached flow at the leading edge, you can maintain a good run of laminar flow, while still controlling the location and extent of the laminar separation bubble. And separation begins at the trailing edge, where it can progress smoothly and predictably as you load the foil.

For an example of such bi-directional sections, see http://www.basiliscus.com/ProaSections/Paper/ProaSections.htm. These are predicted to have comparable performance to conventional NACA sections, but no experimental data are available to confirm this yet.”,”2005-04-30″,”Tom Speer”,”nopswd”,” “,”me@tspeer.com”,”0″

If you are not already reading boatdesign.com, you should try it. There you will find a running dialog about designing hydrofoil sailing moths.

If you design a sailing board that reverses direction, look at the Ogival sections. They are symetrical fore and aft, ie, they have sharp leading edges coming and going. They are a segment of a circle on top with a flat underside.

Hope this helps.

“14”,”819015″,”9″,”Surface piercing hydrofoil||819015″,”I would be enormously grateful for any advice IHS membes can give on the following:
I am nearing completion of a sailboard based test rig which I intend to use to attempt to achieve a semi hydrofoiling single tack sailboard. In short, the system uses a conventional board, truncated aft of the back strap with finbox removed and filled in flat. There is a mechanism that allows the fin to be adjusted in pitch, cant, angle of attack, depth, and -within the constraints of the position of the board and the sailor’s back foot- position. (In other words infinitely adjustable)
I propose to carry out the following test schedule:

1) Fix a conventional symetrical fin centrally as far forward as the back of the board will allow, ie., so it is in the same position as it would have been slid right to the back of the finbox, except it will no longer have the endplate effect of the board. The task here will be just to get the thing sailing. First barage of questions… Will a conventional fin just spin out due to the loss of the endplate effect allowing air to be sucked down? If I wish to fit fences to the fin, how big should they be, should they entirely surround the chord or just be around the leading edge? Should the fences be angled up or down, if so by how much? When I travel at high speed in choppy water on a standard board and the tail of the board frequently leaves the water I don’t immeadiately spin out, so would I even need to modify the fin at all?

Part ii)Fit asymetric foil/s (single tack use obviously) so that the fin will attempt to provide lift, rather than just lateral resistance, and start playing with angles of attack and canting the fin (tip to windward) to provide a more accurate counter to the forces from the sailor’s feet and the mastfoot. I have been looking at the horizontal lift foils that Moths are using, but am not sure if they will work in the context of surface pircing and at the higher speeds. (anything over 50 knots will do:) Once again, will it need fences?
Essentially my problem is that I have spent far too much time actually windsurfing etc. to learn how to design my own bespoke range of foils for this craft. I am capable however of drawing a series of chords from foil coordinates and building a simple foil.
Does anybody have a good idea what foil already designed (and at what scale of chord) might work for these purposes (both the symetrical and asymetrical), and where I might find the coordinates. For ease of fabrication I would like to try a straight untapered foil, perhaps just with a bit of finishing at the business ends that could also be end for ended for the different tacks on the asymetric foil.
Any other comments on whether this has been done before etc. most welcome.
Final inventor’s rant… I believe that the recent regaining of the outright speed sailing record has largely been due to Finian Maynard’s adoption of a single sided rig. After all Yellow Pages’ foils only allowed it to sail on one tack. Why, when water is some 800 times denser than air and fairly primitively rigged ice yachts have bettered 100mph, is the windsurfing world wasting time developing rigs while still sailing on fins that are hugely compromised by having to work on both tacks?
Secondly, Think why a windsurfer has a fin mounted in the middle sticking out of the bottom of the board at the back. I think it might be lazy thinking – the evolution from surfboards which do not have to cater for the same loads, and ease of manufacture. There are two seperate forces delivered by a windsurfer: planing lift of the board and lateral lift of the fin. by sticking the fin out of the board, surely you are introducung all sorts of strange immeasureable vortices at its base. The stuff I am doing at the moment is attempting to divorce as much as possible the two different goals of board and fin. It may of course not work…

Go to www.ebay.com and search for item # 4542861342. The listing expires in five days.

The 61 page soft cover book includes 19 drawings and sketches of various elements of the MONITOR design covering the foils, hull, sail and control arrangements. Also contained in the book are 25 photos of MONITOR and other Baker hydrofoil craft. The back cover features a screen shot from a simulation by Hanno Smits. This book is undoubtedly the most definitive single source of information describing the MONITOR design.

MONITOR Principal Characteristics:

Sail area: 230 square feet
Length of hull: 26 feet
Overall width: 21 feet
Weight 1014 lbs plus operator(s)
Wind velocity required to fly: approx 13 knots
Automatic trim regulation with varying thrust
Steering by rotation of rear foil
Foil incidence angles adjustable in flight
Rolling moment partially compensated by differential adjustment of foil angles

This book will be of interest to designers and engineers who want to know the details of MONITOR’s design and construction. It is also of interest to hydrofoil historians and model makers. People intrigued by David Keiper’s hydrofoil yacht WILLIWAW and hydrofoil sailboat STORMY PETREL may also be interested in this book about an earlier sailing hydrofoil craft.

“19”,”764795″,”9″,”Re: Bruce’s Foil||764795″,”The best information is by Edmond Bruce himself – “Design for Fast Sailing,” The Amateur Yacht Research Society, 1976. I think there’s also some information on Bruce foils in the AYRS book, “Sailing Hydrofoils.”

(Some background: the Bruce foil is like a daggerboard or centerboard placed on an outrigger instead of on the centerline of the boat. The foil is canted to provide a stabilizing vertical force as well as a horizontal force to counter the side force from the rig. This greatly reduces the heeling of the boat, using the hydrodynamic moment from the foil for lateral stability instead of the hydrostatic moments from hull form stability or keel ballast.)

Bruce typically canted the foils at 45 degrees from the vertical (tip inward). The outrigger beams were sized such that the center of laeral resistance of the foils was located the same distance from the centerline as the height of the center of effort of the sail rig. Both low aspect ratio foils and moderate aspect ratio foils were used. His small scale tank tests showed an aspect ratio of 1 gave him the best performance, although he only tested aspect ratios of 3 or less and at low Reynolds numbers. I believe in later publications he used a planform with a circular arc (ogival) leading edge and straight trailing edge.

In his moderate aspect ratio sailing experiments, he mounted the foil on a small outrigger float with a pivot so that it could be raked aft like a centerboard when the foil was to windward. One needs to have the center of lateral resistance aft with the foil to windward and forward with the foil to leeward to get the same directional balance as a centerboard, because the force from the sail is inclined forward.

As for sizing the foil, I’d be inclined to use 40% more area than you’d use for a conventional foil. I’d also go with a high aspect foil rather than the low aspect ratio that proved best in his tow tank tests. Naturally, a symmetrical section is required because the foil has to operate on both tacks.”,”2005-01-15″,”Tom Speer”,”nopswd”,” “,”me@tspeer.com”,”0″

I am French so excuse me if my English is poor.

Congratulations for your kitesurf performance. I am not sure that the solution to go faster is an hydrofoils system.
The limit speed could be caused by the very strong drift force due to the kite.
If you want to experiment hydrofoils, you have to study very seriously these systems ( I think there is not a good “ready to use” system which can be fitted on a kitesurf )

You can use composite material (fibreglass, carbon fibre, epoxies resin) to make hydrofoils (not only metal). You can buy, for example, long sailboard fins (about 50 cm) to begin tests (symmetrical profiles, but it can be used)

Good luck and contact me if you want more information.
