Yosemite
Picked up an almost brand new 2010 Prius (only 6000 miles on the odometer) at Hertz today, and headed east towards Yosemite National Park.
421.3 miles at an average speed of 45 mph and consumption of 49.8 mpg.
That's 678 km and 4.72 l/100 km in metric.

San Francisco Coit Tower
Yesterday was rainy, and the forecast for tomorrow is wet too, so when the sun came out today we saw it as an opportunity to go see the Coit Tower.
Steel Fin Moulds
Jari machined these steel fin moulds for the PIKANTO over the weekend. The fin will be moulded with a clear glecoat, one 200g carbon layer as a surface layer, and one 250g/m2 UHM UD carbon layer. We are going to use either cnc-machined balsa cores, or a 2-component epoxy foam core. The bulb attaches with an M3 threaded rod which will be moulded into the lower end of the fin. At the boat end we'll insert a metal piece with M4 threads so the fin can be attached to the boat with an M4 hex screw.
San Francisco

Tifosi Three
The third production PIKANTO hull is red.
Elastosil M4503 Bumper
Elastosil M4503 is a condensation-curing soft white silicone I am now using for the PIKANTO bow bumpers. The RTV-615 I used earlier was an addition-curing silicone and cured in 60 minutes at +100C. This one will not cure faster at an elevated temperature. The datasheet suggests 24 h at room temperature, but I found 48 h was needed.
