Thanks stringy! I didn't want to just blurt it out so I'm glad you asked!
For the race, I taped over the centerboard well (big improvement) and streamlined the 4 seat scuppers. We found the boat seems to run best with the heavier person forward. Even clearing seaweed occasionally, we averaged about 5.7 MPH over the (shortened) 4.4 mile course with dual Turbofins. My daughter did most of the leg work while I handled the more skilled steering. er, I mean navigational duties from the front while providing valuable ballast.
Pedalers ruled the day -- there were 4 categories where pedaling kayaks entered and they won them all. Three were Hobies -- an Adventure won the men's over 15' SOT (most paddlers have abandoned the category this year as hopeless), a Revo won the men's under 15' SOT, and the 4th was a custom built 17' Seda Swift prop rig that won the men's SIK division. Perhaps they should put the pedalers in a different division next year to give the paddlers a chance to compete on a more equitable basis.
I would post pictures (including our photo finish with a 6 person outrigger canoe (OC-6) which made the TA look tiny, but alas, I'm out of town and have no access to my pic file presently.
With hull streamlining, the TA has a lot of speed potential -- is definitely the fastest boat in the Hobie fleet now. It's the first tandem to run quietly and smoothly. Of course it bounces around more than the Adventure in chop and responds more to wind, but compared with the Oasis it's in a different league. Practicing for the race, I gained a lot of respect for its pedaling prowess. Overall a formidable pedaler!!
