Monday July 6

Let the debates start about which side of the lake to sail from.

Re: Monday July 6

Or, which lake? Gilmer currently showing SE 4. McCullom E 10, G16. Good

Re: Monday July 6

The lake choice is unfortunately too easy. It seems all the beaches (e.g. Galts) on Toona are closed and launching from the boat ramp is not that easy getting out or back in.

The models I've looked at don't seem to have a substantial preference for either side, esp. the exalted Euro model on Windy.com. TBH - none of the models I've seen make tomorrow look very promising. Also, there is greater likelihood of rain and t-storms as the day goes on. In a case like this I think it always makes sense to go to place closest to where you live. If the winds sucks you didn't waste as much time driving to find out. If the wind is good, you have more time for windsport. If you oversleep you probably have to go to the closest place anyway. Also it gives you more time to cuss at your gear when rigging takes too long.

I’m waiting to see wind in the trees. Van is still loaded from trip to coast. Hope to rinse off the sand & salt with fresh lake water.

Re: Monday July 6

It was breezy up there this morning before the wind came in but I had to duck down to ATL for some stuff. Looks dead down here and wet. Hope things improve.

Re: Monday July 6

Radar loop clearly shows the center of the low just south of Macon, moving NE. Bad set-up for wind.
Rain bands make it look tropical. Humidity makes it feel tropical. Good

Re: Monday July 6

If anyone is wonder what you missed this morning - for me with my kit maxed out (Tidwell, 7.0 Flyer loose outhaul, big wing, long mast, boom as high I could stand): pumping opportunities, some which resulted in short flights, others that only resulted in shortness of breath. Anyway I learned something useful - my mast base has been at or near all the way back since I started foiling. Today, it slid all the way forward because I apparently hadn't tightened it enough. I found it didn't change things much. The last flight (with it) might have been the best. Now, I know can use my two bolt instead of single bolt mast base, which should make mounting the sail a lot easier. Oh, and after a half hour of that educational experience, it rained and the wind dropped off. At about 1:20 you can see the mast base has moved. By the end, it is all the way forward.

Re: Monday July 6

Randy, fwiw, I seem to be pretty sensitive to the mast base position. I get all finicky moving it up or back a couple of cm. I'd still encourage you to keep it back to encourage early flight -especially if you are weighting the harness. It may be that you are light enough that it still won't change much (and I'm wrong). YMMV

Glad you had some flight time this morning. It may not be much but I've been out of commission for almost two weeks and I think I've forgotten how to do anything. At least the water will be warm for my reintroduction.

Rain just moved through here again. Kind of disappointing but at least it's not 100 degrees like it has been in Siberia. https://weather.com/news/climate/news/2020-06-21-siberia-russia-100-degrees-heat-record-arctic

Re: Monday July 6

The "early flight" didn't seem to suffer, though with a limited sample and it was impossible to tell which run had the most wind. I thought the last one was pretty light. I was surprised how little wind I was taking off in today, with "moderate" pumping. One problem I've had with the big wing and Flyer combo is that I'd often take off then quickly just stall, or breach, so I think some forward movement may have been helpful anyway. I'm just curious where other people have their mast base. Full forward is 145, all the way back is <130 on my board. I'll probably start next time with the 2 bolt most of the way back. I could probably even adjust it on the water. I do recall a few videos saying 140+ was the magic number, while (I think it was) Balz had his much farther back. It really did seem necessary to have it all the way back on my F136 though.

Re: Monday July 6

Measure from the front tuttle screw - that way can compare directly without trying to figure out if your box is back or forwards in the board. I'm running around 108-110, iirc. Balz runs less than 90. Slingshot recommends 109-112 (43-44").

The take off, stall is just like flying the real thing. If you get too high too quickly, you've run out of energy. As you come off the water don't be adverse to putting it right back down for a second to continue accelerating. You can bounce/skip a few times without much drag penalty. Also, keep pumping once up until you've accelerated a bit (again, like your flying days). Sounds like you're definitely discovering the magic of pumping. None of us wants to do it until we realize how much more quickly we can get off the water. And then we turn into ...

Re: Monday July 6

Yeah the numbers on my board appear to be from the tail end. Measured from the front tuttle bolt the range is about 105 to 120.

On my JP 135 running the Horue foil my mast foot had to be set as far back as possible but the Moses seems to balance best with my mast foot a inch or so back from full forward.
Weirdly though sail size/mast position doesn’t seem to make much difference like in windsurfing. My 7.5, 6.0 and 5.5 seem to all balance okay in the same forward position. Results my vary when I get more experience though.

My 2 cents.

Re: Monday July 6

Is the Moses wing bigger than the Horue? The wing I used today is about 1800 cm^2. I was thinking a bigger wing may not mind having more downward pressure on the front of the board because it can lift more.

I'd tend to agree although a bunch of other stuff comes in like stab angle, etc. (His Moses are from 50 to 100% bigger.) The Horue is further back than my Tillo. When I first sailed the Tillo, I thought I was being launched - literally. I called Alex up and asked for a smaller wing. It took a while to adjust but glad I did. The Horue generally is intended for smaller boards and sails.

As to sail size, paradoxically, a lot of people run their big sails further back. The weight of the rig of a bigger sail needs to be back so it won't push down too much on the nose. The few times I used the MS 9.0, it felt like it was going to sink the nose.

I thought the Horue Xlw was the same area as the Moses 790 but researching showed the Horue XL wing surface area was only 971cm. The Moses 790 is 1550 cm. Makes sense now.

Re: Monday July 6

BTW - one other thing I did this year was to change the stab angle to max lift (before it was max speed) so that may change the dynamics too. I did notice take offs were quicker this season. Interesting about the difference between wing sizes, and mast position.

Re: Monday July 6

Range on my Exocet mast track is ~100-125. Mid-point is generally right but 3-5 cm adjustments make a big difference with F4 foil. Stab angle on it is 3º.
Really curious how my newly acquired Starboard GT-R will do. It came with the 1.5º shim in place but, assembled with that shim in place, the stab measures 4º relative to the front wing. Scratch one-s head

I took a half degree off my Tillo (other direction). Take offs barely slower but it rips... Experimenting with stab angle helps once you have the basics down. It'll be interesting to see what CV ends up with given the various shims he can play with. More angle is also more stable funny enough - it requires you to move the CoG forward and the more forward it is, the more stable.

Re: Monday July 6

The Manta setup allows for fixing the stab anywhere between two positions (most lift/stability, or most speed). I'm not caring as much about speed as early take off. Stability is an added benefit.
