Hi There, i am looking for a new sail for my mach2. I actually have a ka 16.0 and a north H13 i can find some ka 16.3 and 16.5 on the second hand market but i can't recall the differences. Previously there was an article on kasail or mach2 website detailing the sails evolution by model and year, but it was removed. To all the mothies out there, any feedback on difference between ka 16.3 and 16.5 would be really appreciated cheers

Finally real success! I got back out there this week with a fully waterproofed servo, an added lidar sensor and a major code overhaul based on Test Flight 1's test data. Observations were: 1) Pitch control is now much better. While I still think the control loops could be better tuned, I am now getting long runs with very good pitch stability and no more porposing as you get with the wand-based systems. In lighter air, I suspect that the lack of paddle / wand drag will allow me to fly more easily as well. 2) Servo waterproofing worked great. 20 knots of wind and lots of spray

Hi A-Class foilers, I start this thread to have a forum for some basic how-to exchange on foiling A-Class catamarans. I am proud new owner of a DNA F1x catamaran (for single handed sailing) and also sail a Whisper catamaran (works best with crew) for the third season. I am a weekend recreational club-sailor, who loves cool technology and nature at the same time. However, I still have to figure out if and when there is ever enough time to prep and sail the first club regatta. Hence you will find my priorities more on how to mount a gopro, rather then regatta starting-line tactics ;-)

Hi guys, I am new to this forum and new to mothing, so spare me if creating a new thread is not the right way to go about this and also spare me if I am asking stupid questions. Anyway I recently bought an older moth, homebuilt hull from an assassin mold as far is I reckon, different parts mixed together for the rest. All in all its working fine and with some tuning and learning I got it going. I can't however figure out the issues I have with the Rig/Sail/Cams combination. Somehow the cams keep on falling off the mast (during manoeuvres), if the cunno and vang are both not tensioned very

We are lucky enough that we have a small band of Whisper Sailors playing around and posting videos and rigging / tuning notes. - @Flying Tiger Whisper is publishing his videos, including some how to rig it, at https://www.youtube.com/channel/UCipkSggLhwNpIpeSGgIMBDA - @flyinggorilla is publishing... videos at https://www.youtube.com/channel/UCwhb6u4A_Hy-c-eJbMLW7bg amazing docs and anecdotes at https://github.com/flyinggorilla/whisper-foiling-catamaran - My own stuff: videos https://www.youtube.com/cha

I got out Monday for a first flight for my digital flight control system. Overall it was a big success! The one thing I cut corners on to get out there was fully waterproofing the servo. I felt that the likelihood of a turtle capsize was low (my last one was months ago). Of course, what did I do after 90 minutes out there? Turtled the boat and killed the servo--HAHA! But still a great day with lots of learning and successes: 1) Being able to "arm" the system at the press of a button was a major convenience. When the system is "not armed" it is as if the wand is all the way up and

Adjusting Altitude Setpoint and Other Params
DerekF posted a blog entry in Digital Flight Control System for Foiling Dinghies
Hey team, just shot a quick video on my solution to adjusting altitude and some of the other prototype variables. First flight is TODAY!-

Servo Actuating Flap with Torque to Spare!
DerekF posted a blog entry in Digital Flight Control System for Foiling Dinghies
Electronics module and servo now fully mounted on spirit and actuating the flap with torque to spare! First flight in mid June is on track! Last steps are some linkage adjustments and test tank time (in my hot tub)! -
See the linkage working with the servo and altimeter to control the bell cranks and foil flap. First flight should be sometime in June!

Another update from the land of digital flight control systems! Integration I now have all sensors talking to the Grand Central board and the algorithms (PID loop, ultrasonic sensor filter and smoothing, etc.) performing as designed. The wireless remote is also working and allowing the user to adjust PID Parameters, Altitude Setpoint, and Smoothing coefficients. The LCD is putting out status messages and feedback when the user is changing parameters. I am also collecting all the data from accelerometers, gyros, ultrasonic sensor, battery cell voltages, etc. and storing it to an SD ca

Another quick update, A productive weekend ended up with an IMU (BNO055) and a waterproof sonar range sensor (JSN-SR04T) being integrated to my Arduino Mega board. Both are yielding good data and easy to work with. I also am able to write commands successfully to a spare servo I from an RC Tricopter. I am still in the process of selecting the correct servo and identifying the correct attachment point(s) for the servo to flap linkage (please see and comment on servo math below). Additionally, I now have a PID library running giving servo commands based on the measured elevation.

Time for another blog installment of the Digital Flight Control System for my UFO. I have been busy at work on the project and making good progress toward a first flight in early 2020! Also attached is an updated block diagram with details on various subjects below: Data Logging: In my last blog post I mentioned that we needed some sort of data logging to really get into the meat of how well our control and filter algorithms are working. Post processing data after getting off the water will also allow us to see if there is data being generated by sensors that could improve

Ok team, here goes my first blog post. My goal here is to build a Digital Flight Control System (DFCS) for my UFO using a sonar range sensor as opposed to the wand. The design needs to completely mimic the performance of the wand system currently in the boat. The system needs to be fully removable to allow for One Design Racing if desired. A few design guidelines... Improvements to current control system: 1) Sensing wave terrain out ahead of the boat 2) Not engaging the mainfoil flap until the boatspeed hits 7 knots to reduce drag while floating 3) Toggle settings

Sea trials were supposed to take place this past July, no news from the company. Any insight out there?
