I haven't seen much of a shift in CA. Like any sport that explodes in popularity, there is going to be a healthy decline. I was at a break a few weeks ago. A guy that resembled Bob Miller was out on the original Laird SUP with his dog. It was like he was on a conveyer belt paddling to the outside peak, then riding the wave all of the way in, never he nor his dog dropping in the drink once. It was like he was in the carpool lane in terms of right of way in the crowded line up. The SUP scene that I have seen first hand seems more popular in SoCal than NorCal. The beaches got hammered in SoCal this winter, messing up some of the beach breaks, but SUPs still work. Foiling is fun, there is a reason why people are addicted to it. But it all comes down to what equipment works best for your local break. Me personally, SUP has taken a bit of a dip, due to an uptick in my prone surfing. I tend to gravitate to the best equipment based on the current conditions, which could be SUP, prone, or kite. Don't worry about what what other people are riding, ride the equipment that feels good to you. Stoked on your El Savador trip. Welcome back.

I agree with B-walnut, should be a nice next step progression board. A guild factor of 1.5 is a really fun size in my experience. A guild factor of 1.3 is a nice factor to end on. Advanced surfers typically fall in the 1.3 - 1.8 range. https://www.blueplanetsurf.com/blogs/news/sup-board-volume-recommendation-chart/9'6" ist still a good length that maintains glide. Having an inch narrower will have less drag, so help maintain glide. I think you will enjoy this board when the conditions are clean.

Interesting. I am curious if cleaning will have any affect on performance. My work had a traditional panel array cleaned, after a decade of use. and saw no change in performance. They did see a big improvment in performance during the summer compared to winter months. I monitored the logs over a decade and saw no drop off in performance over respective months.

Thanks Robert, The Jimmy Lewis chat was awesome. Love your signed World Wide shirt, wear it with pride. I have the Rush Randle air chair aluminum hydrofoil which I use for kitesurfing, he welded a mini tuttle top to fit onto his board. Thst seaplane V in the front of jimmy's board wth hard rails looks sick.

I'd listen to your gut with regards to the 8'8" versus 8'5". That planshape is good if you want narrow and less rail length. I believe the reason the 8'2" Quatro was so unstable is because of the pulled in nose, making the board feel 6" shorter than a choptop style board so like a 7'8". But the Speeed is not a quad? What about the 9' x 28" Kalama? Or you may want to check out the quad L41 S5. https://www.l41surfcraft.com/models-sup"Ridden narrower than your normal board with little effect on overall stability. The parallel rail outline makes this one paddle and catch waves like it's a much longer board. Single concave entry and through the middle transitions into a channel bottom to make this model loose and fast with control!" I am similar weight, this is my race to the bottom board at 7'6" x 28.5" 110L. It is stable for it's width, but I am still getting comfortable with it in our usual choppy conditions. I really like the grip of the channels. I reckon ~8'6" would be comfortable.

Some great pop up videos in this thread. I came across this one where he talks about staggering the hands, to get the shoulders and hips turning earlier. https://youtu.be/7qFScB4LzUc

The build of a wing is similar to a kite. Snowkiting has been going on for decades and I have never heard of icing causing problems with kites. If you are concerned with the coating of the wing, I have used the product Aerospace 303. It is a uv protectant that makes the kite/wing look brand new. Think of it like armor all. In fact I prefer it over armor all for my car. Perhaps contact BigWinds to get there input.

Lindsay Lord studied aspect ratio in planing hulls: https://etchellsfleet27.com/wp-content/uploads/2019/08/Naval-Architecture-of-Planing-Hulls.pdLindsay Lord found that aspect ratios(W/L) 0.35-0.45 to be most efficient for holding weight. Your E3 4'8" x 26" had a W/L of 0.465, above that range was was your least favorite. The E3 5'10" x 29" had a W/L of 0.4149 and was not to shabby. The E3 5'3" x 22" had a W/L of 0.35 and was quick to take off The 8' x 30" montser had a W/L of 0.31 and was very easy to get on foil. The Sunova Carver 5'10" x 20" had a W/L of 0.29 #untested The Barracuda 8' x 21" had a W/L of 0.22 and was easiest board I've ever had to get on foil The Custom 6'3" x 20" had a W/L of 0.27 and was extremely fast off the water. With hydrofoils, things are different as you are not concernced about holding weight, you just need to build enough speed in order for the lifting force of the foil to take off. Dave Kalama discovered that speed is your friend for early takeoff. I would think there are other things to consider. Were you using the same foil when comparing all of the boards? Was the mast position tuned for each board? Were the bottom shapes off all of the boards the same? I would think that bottom shapes would be a big influence on ease of popping up. And was the same tail used for all the testing (same foil profile, size, same shim angle)? Same energy in the water? (different days, different energy) I'm am not sure about your equation. You are focusing on Guild factor. Guild factor could have an influence, but I would think you would have to be at the extremes to feel much of a difference, G/F < 0.8 or > 2. Rather than Guild factor, I would be interested to hear the relation of surface area (or projected area) of a foil to a riders weight. A smaller lighter rider can get by with a smaller faster foil. Where a heavier rider will need a larger foil, but have to deal with the increased drag. Lindsay Lord also noticed that the optimal angle the board makes in the water changes with respect to aspect ratio. Boards with aspect ratio .2 had a planing angle of 0.75 deg aspect ratio .3 had a planing angle of 2 deg aspect ratio .4 had a planing angle of 3 deg aspect ratio of .5 had a planing angle of 3.75 deg aspect ratio of 0.6 had a planing angle of 4.25 deg I would think that as the optimal planing angle changes, the aspect ratio of the foil can become important, where you would want to dial in the optimal aspect ratio (lift/drag) and area of the foil with the speeds in question. And as some foils have different cadence for optimal efficiency, I wonder if having a board with an aspect ratio that is in the range of the optimal planing angle would make popping up easier. No doubt a complicated recipe to get it all right. My hat is off to all of the early adopters paving the way. I use foils for kiting. My first foil was a 5'6" x 16" 2002 Rush Randle W/L 0.29. Second board was a liquid force 4'2" x 19.5" W/L 0.39 (with 2017 Cloud IX foil). Different foils for each board. Boards have completely different bottom contours. Volume unimportant. The W/L 0.39 has a lower takoff speed, but the foil section is thicker and probably larger area too.

I agree with Badger regarding surface prep. I put them on a board to make a tail handle. The board was painted so I sanded it down to the carbon layer. I used 5 min epoxy resin, and put excess so it formed a pool to cover the borders of the EZ-plug. Never had a problem with mine using the Beasho elastic tail handle design. https://www.standupzone.com/forum/index.php/topic,25430.165.html

Tis the season, my buddy just buckled his NSP Cocoflax. 3 layers of 6 oz sounds good to me. If you feel like it needs more, I would reinforce the rails. Was there any evidence of compression on the top deck due to standing? It is my understanding that with repairing buckles or snaps, you want to get close to the original glass schedule. If you go under, it will be a weak point. If you go over, then it will be a stiff point, causing stress on either side of the joint. "with long, staggered overlaps of the reinforcements, in order to create as smooth a transition as possible from the original lamination to the new" Snap repair here: https://boardlady.com/snap.htm"with an extra two layers of 4oz cloth on the rails." Buckle repair here: https://boardlady.com/seatrendnose.htmLamination strength explained: Are you going to be able to match that yellow paint. I had a yellow board that I tried to match paint. At first I went a shade lighter, which made it looked bleached (I felt it looked ugly). Then I went a shade darker, which made it looked dirty, which I liked the looks of better.

Need to do a video building the whole board. I think there are a few people that would enjoy it and want to take a crack at building something that keep thinking about but is not being produced.
That would be legendary. I watched the entirety of "How to Build a Hydrofoil: Overview, Planning and Design (Video 1/15)" from start to finish: https://youtu.be/af-iiFLuzis?si=QDDcmLQW2jRxKfUK

For 2024, PSH has a new line of Rippers designed by Terry Chung: 7'7" 28" 4.25'' 97 liters 8'1" 29.5"4.25'' 117 liters 8'7" 30" 4.25'' 127 liters 9'1" 30" 4.25'' 133 liters 9'7" 31" 4.5'' 147 liters They come in two different kinds of construction. PX1 is composite Paulownia. https://www.paddlesurfhawaii.com/products/2024-ripper-px1The other type of construction is PCX which is composite Paulownia and Carbon Fiber. https://www.paddlesurfhawaii.com/products/2024-ripper-pcxFor those not familiar with Terry Chung, he is a legendary waterman who previously designed boards for Laird Hamilton. I for one am a big fan of the original PSH designs by Blane Chambers, especially the builds prior to Boardworks construction and before the fragile Bamboo construction.

I hope you wear a leash & pfd, and bring lots of water. I visited SD beaches this summer and the water at Coronado Dog Beach was by far the coldest. There is some deep water out there. I would listen to your gut and try to minimize your risk. If it was me, I would have your friends trip be the goal to work up to. But I would break it down into smaller trips first. 1) If you are unsure about ocean paddling, I would launch from Dog beach and paddle to Zuniga jetty to check it out. That side of the island is the Navy beach so that entire section is a black hole, no exit. 2) If the Zuniga jetty looks doable, then how about launching from Dog Beach and looping the Navy base end exiting around the other size 1st / D Ave. 3) Then I would launch from 1st st / D ave and exit at Glorietta Bay. Gauge how you feel from each and decide if you have what it takes to make the entire journey in one shot.
