Finally got a working model of the HIPE 5' 3" Wind-SURF board.

The NEED: Winging is OK...But I want an Multi Use Board to Windfoil and Wingfoil
The CHALLENGE: How to get the mast track on the deck. I consider a bolt-on tray, but it would be too big and heavy. Straps can't handle the forces. Glue-On was the answer.
The FORCES: I came across this great piece of work by Dietruch Hanke.
docplayer.org/132854945-Windsurfmechanik-grundlagen-zur-berechnung-der-fahrleistungen-dietrich-hanke.html . Great engineering analysis. A 6.5m sail and mast exerts 500N of force (112 lbs.) on the board. Where as, small glue on anchor points for inflatable boats are rated at 50 lbs of force. These anchor points are 17 sq. in. (or 6.47lbs/sq in.) My "mast track anchor point" is 70 sq. in on the deck. So basically this FRANKEN-MOD can handle (70sq. in x 6.47lbs) 453 lbs of force. My biggest foil sail is a 5.5m, so I should be OK
The GLUE: No need to skimp. The best stuff seems to be H-66 Vinyl Cement. Video demo's show the underlining material will fail before the glue joint does. So any failure = sinking HIPE.

Used MEK Cleaner and 3 coats of glue with 3-5 min. drying between coats. Its on tight. Other iSUP vendors have glued on mast bases in the past, so it should work.
The MAST BASE: Basic 10" windsurf unvented mast track. Could of went shorter but wanted the mast base travel to balance the foil.
The MOUNT: 2 Scotty Glue On Mounts.
www.amazon.com/Scotty-341-BK-Glue-Inflatable-Boats/dp/B0793PLQL5. Needed 8- 1.75" Stainless machine screws to secure the track to the Mount. Basically mount it as far forward as possible given the length of the board. With a 10" mast track, the sail is 39" (at midpoint) from the front bolt on the foil mast...same as my Slingshot Wizard 105. Some Dremel work was needed but the mast tray fits snug in the Scotty mounts. FYI, My son and I designed a custom mount in CAD and attempted a 3D Print, but the part was 30hrs print to would be to heavy. 3rd party printer wanted $150 to print it. The Scotty Mounts are cheaper and "glue-able".
The ASSEMBLY: With the mast track is "snug but floating". A 12" ABS 1/8" plastic sheet was cut down as a cap to hold the mast track in place. The sides are ABS plastic as well and glued to the cap with JB Weld and wrapped with FiberTape (basically a carbon fiber duct tape), it really strong.
www.amazon.com/FiberFix-38201-Repair-Wrap-Tape/dp/B00B297WDG. At 175lbs I can stand it on with no flex.
The PLAN: Will leave the mast track tray on the board since it still folds nicely (See below). Waiting for the ICE TO MELT and warmer weather, then take it out and Sail it. Will most likely mount new front foot straps (current straps are too far fwd), and possibly rear straps using glue on anchors.
THX GONG!
