    14' Stunt S9 Foiling Cat

    Martin: yep. About 300 posts ago the A cat crowd couldn't believe we were sailing the S9 without foot straps. The videos show they are not needed.

    14' Stunt S9 Foiling Cat

    Everyone: sorry for all drivel on here, but we were pretty pumped. Will take awhile to process everything. Our group included a Psychiatrist from Minnesota, a businessman from Austria, a software guru from Argentina, a Mechanical Engineer from Italy, an enthusiastic and helpful 8-year-old boy, and a wordy old retired fart from Texas. The exchange of ideas on land was great (really good bars and restaurants down there), but to actually transfer to other boats out on the water was the highlight of the trip. Sailing another boat for five minutes gets you an education that you just can't get through words. We need to do more events like this - collaborative, not competitive.

    Martin, I am just fishing for general comments. In your video montage you showed the world how we swapped boats without a chase boat and you documented three completely different approaches to achieve wand-based foil control. Fun to see the interaction of a Dad with his happy son. It's very interesting to read the formal papers on foiling and to share opinions and experiences in fora like this, but videos like yours pretty much show that all three approaches work. Pretty sure other methods are workable, too. Parallels to aviation's early days come to mind. Breakage: no major breakages occurred - not more than one hour of sailing was lost due to breakage - we lost much more time to the tropical storm and the lightning. Cobblestones: yes! that's the feeling. The Whisper had none of that - quiet and smooth. I never foiled the UFO enough get that effect. The S9 can be damped by slacking the bungee providing downforce to the wands (cleat in the middle of the tramp). That may affect ride height. Easy to document by video - need wind, though. Cobblestone effect to me just means that you are going fast - nothing else. Don't see how it can have any other benefit. Perhaps someone can educate me. Interesting to note that there are no foot straps on the S9 or the Whisper.

    Remember the discussions about wand placement? These clips were filmed on flat water, and it might be different in chop or swell, but do you see any differences here? FYI: "foil base" on the S9 is about 54 inches. Whisper appears to be about double that. Difference shows up in helm sensitivity and ride quality. Your thoughts? https://youtu.be/48W8y8sfWXo

    I hope to get more time on the Whisper in the coming months - just a beautifully engineered boat. Mast and main looked huge. Thank you for sharing Martin!

    4:1 ! I could barely move it at 6:1.

    A few more notes: the S9 with Code Zero can develop severe lee helm - you must sheet in the main to get it back to neutral or slight weather helm. In this case you are sheeting in to balance the helm, not to trim the main. I rake the rudders back slightly to compensate, but if you then sail in higher winds, no code zero, without moving the rudders back, you get too much weather helm. Martin, we were sailing with the rudders in "code zero position" and with the resultant weather helm. Two turns on the adjuster - on the water - would have fixed that. I don't what I was thinking when I said "just sheet in". That was a bad answer. Sorry about that.

    It was just too much for me to pull it in quickly - I should have let Alec handle the main (as Martin suggested).

    14' Stunt S9 Foiling Cat

    As Martin said, with me and Martin driving, the S9 in those conditions was a markedly faster boat. I have no idea why. The videos will show that the Whisper tends to drag the sailors butts in the water. On the UFO the solution is to sheet in quickly and let the sail pull you up. I suspect the Whisper will respond similarly, but that huge mainsail only had a 6:1(?) mainsheet and I was far too wimpy to sheet it in fast enough. End result is you have to really honk on it, but it does eventually right itself and foil nicely, but you lose a lot of time getting your butt out of the water. The S9 is not a good light air boat. That's why the jib and code zero were added. The Whisper may have an edge in light air. The S9 requires a lot of foot work fore/aft and a lot of coordinated tiller work to keep things level. Can't do that while sitting on the hull. My summary below, not quite the same as Martin's (but that's why we have both chocolate and vanilla): The Whisper is a highly-refined high power machine that takes more skill and strength to sail quickly than the S9. Perhaps the fittings and such are lightened to the point that failures occur - but isn't that what you expect on something like this? The S9 target sailor is the more mainstream club-type sailor. Ex Hobie-catters, old people, those who rather just fly around the bay than race Alan Ashby. Accordingly, the S9 has proven to be quite durable if you keep it away from F-18s and power boats. The penalty is a few extra pounds (~190 pounds with jib and code zero). A good tradeoff to gain durability I think. Anyway, going to work on more videos - next one will show my fastest and Martin's fastest.

    Please read this before you watch the video; This is boat abuse: max recommended is about 210 pounds. We are sailing at about 335 pounds body weight, plus wet gear. Crew is Alec Bollorino, moved here from Italy, Civil Engineer building big things in Miami. I am half deaf and I don't speak Italian, so you might pick up a few miscommunications in the video. Alec is trying to sell his rotomolded Hobie so he can buy an S9. If you watch the speeds, you'll see that Alec achieved a higher speed than I did. S9 is NOT set up for people sitting on the hull and foiling. You simply cannot shift your weight quickly enough to keep the boat level. Please don't try this at home! https://youtu.be/2zwSAkdFl5Q

    S9 and Whisper had a Chamber of Commerce day on the bay yesterday. Martin sailed the S9, I got to sail the Whisper, Alec crewed on both. I wouldn't recommend this, but the S9 foiled with two aboard: 185 and 155 pounds. My best on the S9 was 24 mph, Martin, first time on the S9, clocked 23 mph. I did get the Whisper to foil with Alec as crew. Whisper does not react the same way as the S9 (I've yet to sail two foilers that react similarly). S9 seems perky and lively, Whisper feels like a much larger boat. Video in the works, stay tuned.

    It looks like the S9 in Miami is available to view, sail, or buy. Please PM me for more info.

    sail(plane): I didn't get to sail the Whisper yet, but for me the S9 on foils is more stable and easier to sail than the UFO, but the UFO is easier to set up, and you don't need experience with a trapeze. Personal preference between these two boats: if you have dinghy experience you will likely prefer the UFO. The Whisper is a very light boat with a tall rig - really need to be on your toes in gusty conditions. Hard for me to say more without sailing it. We did get to sail the Whisper and S9 together on the bay yesterday, but the Whisper sailors were still training, not pushing it.

    Yesterday started with spectacular lightning and heavy drizzle. A little after noon the sun and the wind arrived. The Whisper, UFO, Weta, and S9 went out for several runs. The sandy beach on the narrow lagoon at Miami Rowing Club is a sweet setup for Martin and the other sailors. Martin and son Alessandro trained a lot on the UFO. Nick, Martin, and Peter tag-teamed the Whisper while I sailed the S9. (Nick flew in from Austria, Peter from Minnesota.) Martin arranged for me and my wife to rent a cottage from his sailing buddy Javier. Javier's cottage was a great place to stay in Miami, highly recommended. Javier sailed with his daughter on a bright yellow Weta. The S9 did not need the Code Zero yesterday. Nice steady wind out on the bay, moderate waves. Nuclear, unstable gusts in the lagoon made for a real joyride through the moored boats and the jet skis. The S9 handled the conditions with its usual pep and stability - it was a real joy to sail in those conditions. Best foiling conditions I've seen in many months. Boat could go from 5 knots to 20 in about three seconds - thrilling! The S9 never capsized or broke anything, but the knots on my home-built soft shackles don't seem to hold very well. Bill and Eric Roberts dropped by to chat and take pictures. They had good questions - stimulating conversation - thank you Bill and Eric! (Bill and Eric are probably still laughing at my aborted launch off the beach yesterday: I put down the rudders okay, but an unattended line jammed the steering. The S9 just continued its turn into I hit the beach. Rudders weren't cinched down yet, so no harm done. Just a dumbass at the helm. Eric helped me turn around and get started again - thank you Eric.) The group ended the day at a nearby Mediterranean/Chinese/Mexican restaurant. We chatted and munched on a sidewalk table until sleep took over. Woke this morning to find us under Tropical Storm Gordon - don't think we'll get to sail today. Martin should have comment and video on the Whisper thread.

    Sailed Friday in the bay. Mats of Sargassum weed made extended foiling difficult. The S9 rudders would cavitate spectacularly when they grabbed a load of weed. Very pleased with the code zero - makes a huge difference downwind. (Furling requires a tight mainsheet.) Martin's son (8) sailed with me on the S9. Getting under the high bridge out to the bay was an adventure: current was faster than boat speed. Took two tries. This never happens at the lake . The Whisper found a sand bar. Weta went out with us, didn't mind the weed as much as the foilers. New maneuver: when weed loads up, stay on the wire, head up, sail backward a bit to clear weed, then bear off and off you go. Looks odd, but it works. Sailed yesterday in the upper bay - good wind. Alec (from Miami) sailed the S9, several of us sailed the UFO. Best sail I've had on the UFO. Martin hosted a nice bbq at his condo for all the sailors - great fun. Thank you Martin!

    First Miami group sail today for the UFO, S9, and Whisper. The older young man in the picture (Martin's son) ran the Code zero, the main sheet, and steered a bit on the S9. For some reason, he crashed and fell asleep at dinner. Martin, thank you for arranging this! Great fun!

    vaplaya: I think the precision socket is the key - when mated without the screw, the parts still don't separate easily. The long screw keeps the assembly rigid. There is a worm-gear mechanism at the top that allows gross aoa adjustment for entire board/foil. We usually set this at max lift unless it is blowing like stink or if it is displacement conditions. Your weight shift fore and aft significantly alters aoa: most sailors weigh more than the boat. The flap at the back of the foil is wand activated. All in all, the system works very well - predictable handling, stable. This is a little boat - less than 14 feet. Certainly not the fastest foiler, but perhaps the easiest to foil.
