Chesapeake Bay Magazine's and Boating's John Page Williams put the 29z through its paces on the Bay. People continue to be amazed how much performance we're getting and how quiet the boat is with the Volvo D4 260 HP Duoprop sterndrive. 80 decibels at 23 knots and 33 knot top speed. As for fuel economy, the 29z burns 8 gph at 25 knots vs. the 34z's 11-12 gph. At 30 knots, the 29z burns the same 11 gph that the 34z burns at 24-25 knots. At 5.8 knots, the range is nearly 1100 miles.
