These are the last two TBG3s. The one on the left is for a 300lb rider, while the one on the right is for a 170lb rider. The biggest difference in these last two G3s is the switch from a well-defined tail concave to a blended double concave tail with slight V. While I prefer quad fins, both customers chose the twin fin set-up.
I start work on the new TBG4 next week. This board will be 3″ longer (at 48″), than my old TB3. The extra length will necessitate changes in the outline, the foil and fin position.
