Re: Monolith 2001: XLPE
This is a CAD figure for the 48” Channel-Tail model. Channel size is the same in the 42” model ridden in the video previously linked and the photo above — board planshape is similar. The bottom surface inside the tail channel provides indirect rocker. The tail channel functions as a low-drag, finles...

Re: Lindsay Lord Hybrid
Sorry for the late reply. You two our obviously are a ot more scientific than myself. So as a rule of thumb you tend to stick around this AR. I don't want to digress away from the topic but what is Greenoughs AR? As a retired scientist, my perspective is influenced by science. While I was building ...

Re: Lindsay Lord Hybrid
matt23, I have not been ignoring you. Just finished a marathon write-up (Fri-Tues) of a non-surf design I had to submit by Tues. afternoon. I encourage you to read Lord's Chapter 2 about Aspect Ratio (pp. 11-19). When a watercraft is planing, only the bottom surface is in contact with the water (Fig...

Re: Lindsay Lord Hybrid
For those not familiar with Lindsay Lord, he was a professor of Naval Architecture prior to WWI. He did his graduate studies at MIT. He held a supervisory role with the US Navy. He researched planing hulls. Lord’s information about planing hull Aspect Ratios is found on pages 11-19. https://etchells...

Re: Lindsay Lord Hybrid
The chamfered hull is simple to make. Start with a rectangular blank with the desired dimensions. Shape the long edges on the bottom of the rectangular blank first to create the angled chamfers. Flip the chamfered side down and draw the desired planshape outline on the top (deck) side. Cut the plans...

My most recent builds/experiments create a rectangular planing surface for the bottom (parallel edges). Bottom chamfers allow me to use traditional curved rail outline templates.
The rectangular shape uses an Aspect Ratio in the Lindsay Lord 0.4 range.
I call them Lindsay Lord Hybrids.

Re: new pad?
I think the hydro turf you are talking about is super thin? The Hydro Turf brushed/flat EVA surf mat sheet is between 3/16” to 1/4” thick. Decided to try it to add some traction as well as cushioning — it looked more comfortable than their textured surfaces (diamond, etc). For a future build, I pla...

Re: new pad?
Thanks. This answer I gave to a question on the new Sways might be useful here: I used the HydroTurf “flat (brushed)” surf sheet that comes with self-adhesive backing (link below). https://hydroturf.com/products/sup-surf-traction-mat-sheet The self-adhesive is/was for fiberglass surfaces.

Re: Monolith 2001: XLPE
Important tip for XLPE boards. Don't lean them up against something in direct sun. The side that heats up warps toward the cool/shaded side. Found that if I leaned the opposite (cooler/shaded) side out in the sun for 20-30 min in the same sun heat, it warped back. Then I placed the board on a cool f...

Re: new pad?
Two weeks ago, I added this blue, brushed/flat HydroTurf EVA deck pad to one of my first foam and glass channel-bottom BB prototypes. Far from perfect, but fairly decent for a first-time deck pad application. Should do the job. Will see how well it holds up. I smoothed the deck-pad edges with a micr...

Re: new pad?
I'm reshaping an old board and I'm gonna need a new pad. Does anybody have a recommendation? I'd like a piece about 24"x36" and I'd contact glue it. I can locate some but it's got that raised diamond pattern and I think it's more for standups- not bellies. Where are you located? Hydro tur...

Re: Strip plank build
In the skateboard world they use a 2-pc press for bgreen’s suggested method. With high enough density XPS, you can use 2 halves of foam with shaped desired rocker and place the glued up (title-bond III) ply into a vac-bag between the foam press pieces. On the silverfishlongboarding skate build forum...

Re: Monolith 2001: XLPE
Thanks Bill. It only needs to last a few days. I wasn't thinking of sandwich as all this needs to fit into a suitcase. Where do you buy your XLPE? My searches seem to only identify cable suppliers. I get my XLPE in the US from the Foam Factory in Macomb, Michigan. For short-term, XPS housing insula...

Re: Monolith 2001: XLPE
do you know if you could ride a board of Divinycell and wood, without fibreglassing it? Divinycell is closed-cell and is reported to be water resistant. Couldn’t find % water absorption data on a quick search. Looks to come in 4-5 pcf densities with decent compressive strength. Would you sandwich t...

Re: Monolith 2001: XLPE
I may have found an event where I can test my boards in consistent wave conditions -- Waco, TX; 10/3-10/4, 2022.
(Need to quickly build a channel-bottom TR-42 and a NACA-rail, wing-tail 47.5" to bring along also.)
