I just finished building a Wherry Tandem earlier in the week and took it out for its first row yesterday. Here it is on the floating dock at Pier 40, at the end of W. Houston St. in New York City. The big block building is the Holland Tunnel ventilation tower, Jersey City is across the Hudson River in the background.
I'm rowing it as a single for now, or as a trainer with a cox/coach as a passenger.
I spent about 150 hours building it, spread over the past five weeks.
The wherry is a delight to row. Very stable, but it has a nice run. It tracks well, but steers easily too. You can see that the water was calm and flat yesterday, but there are always ferry boat wakes in the harbor and it handled them just fine.
