Hi Bob,
I have used a fin for so long now I can’t remember how they run without, but I can add one later if necessary, I see lot of people on this forum run finless and they seem to make it work. The anticipation to get this board in the water is building.

The glassing is finished, now the most difficult decision to make what colour and pattern? I am not certain about fitting fins yet. It has lost the organic look of pectoral fins and is more aircraft looking

Hi Bob ,Brett I don’t want to sound egotistical going on about how fast my board s are, but it seems quantifying incremental changes in surf craft is very difficult. In cars, boats and planes you can read a spec sheet and by glancing at the HP and weight you can tell how fast it will be. Surf craft ...

Hi Bob
Thanks a bit mind numbing , some very interesting points, I like the trace device , but its all average speeds and not actual board surface speed,

Hi Brett, I need information on surfboard performance telemetry, what is out there, I think I need a speed o meter or something to measure surface speed, there must be a small speed sensor out there. GPS is too average, like if you go forward 2ft but drop 6ft GPS can’t pick that up. You talked about...

A poor image of intended water flow.

Here it is 3/4 finished,SR-72C with Hydro Gravity Drive .I think it will run very interesting lines on a wave face, it has got a bit heavy 4.5KG,but it is bullet prof
for running over slow moving water hazards like SUPs,and longboards.

Thanks i got

Hi Bob,
Not sure were to find your pm.?In fact i dont know what a pm is

Hi Brett, It is very interesting all the different ideas out there,it can be difficult to be certain all this complexity is improving riding a wave,we all have differnt goals on a wave.My improvement goals is to be the board that rides the longest on any wave on any day.Like on a close out day i wan...

Hi Foil afflicted ,
Getting close to glassing,this is when i embellish the finial shape ,a lot of standing around with hand on chine with a 1000 yard stare, it can take days.

Hi Brett,
I am no sure what CMS is ,but it is all hand layup on XPS with brushes and rollers,mostly 6 oz cloth .I like useing ridges and concave sections to strengthen , the tip half of the foil will have a laminar- flow section blending to the flat center

Final foil position.

Hi Brett,
The torsion box has been glue in,and i am close to the finel cut on the board. this board will be very thin with hard rails,i am trying to keep the foil as light as posible ,with foam box beams ,its a new method to me!! but thats how we grow.

Hi brett, This looks like you should cut the side fins off and screw a foil onto that v rail, that to me is the correct gape between board and foil.To lessen inertia coupling, it looks like something was screwed onto that rail ?.That to me looks like a very interesting project.It looks like a foil a...

Hi Brett,
I have started the SR-72 project.Here are some pics,this part takes the longest agonizing over were to place the foil,and angel of incidenc.my other boards have about 3deg positive angle,i think this will have 0.What angle do you use

Hi Brett,I thought we were not on the same page with this foil thing for a time,but now realize both the foil types you are talking about are on my boards but packaged diferantly ,i have the wing foil under the front to back foil witch is the tail rail.The wing foil is the pitch pivot,but plaining o...

GOPR1318.JPG GOPR1319.JPG Hi Bret,Here are my hand trimmed T foils,i used to run on my boat, a sail boat is a great way to play with foils .Keeping hand trimmed is a big problem,becous of raped speed change,i found it hard to make a neutral running foil,i started to play with water level trimmed fo...
