Burt Lake Speed Test
Posted: Wed Oct 14, 2015 7:34 pm
This is an informal performance report of a short duration speed test conducted recently in Burt Lake.
We were boating in a small fleet of Boston Whaler boats (and one Pursuit), heading upstream in the Indian River (northern Michigan), on the last weekend of September. It was a beautiful fall day, very warm, very sunny, and light winds. As the fleet was exiting the mouth of the Indian River channel at the southern end of Burt Lake, I proposed via VHF Marine Band radio that we have a bit of speed competition.
I informed the fleet that I would be getting on plane at full speed, heading across the lake to the Crooked River channel mouth, and invited all participants to see if they could catch me. I figured this would prompt a good boat race.
I took off in CONTINUOUSWAVE, my Boston Whaler REVENGE 22 Walk-Through Whaler Drive with a 225-HP E-TEC turning a MIRAGEplus 17-pitch propeller, but actually I did not go to full throttle. We loafed along at about 30-MPH, watching the rest of the fleet getting going in pursuit. In short order the LUCKY TWO, a monster Whaler 25 Walkaround with twin 250-HP E-TEC engines was closing fast, along with the Pursuit 235 Offshore OUTLIER with a 250-HP Yamaha. I pushed my throttle ahead, and my boat responded by getting up to a very respectible 44.5-MPH (all speeds are in statute miles per hour as we are not on the high seas but on an arm of the Great Lakes, where the official speeds are in statute miles per hour). The E-TEC was hitting about 5,750-RPM and we were really flying along. By now the three boats were maintaining a fairly constant pace, with no one really pulling ahead.
Astern we still had a DON's DAUNTLESS, a 17 with a 115-HP Evinrude Ficht RAM Injection, a big Boston Whaler 345 CONQUEST with triple VERADO 350-HP engines, DRIFTWOOD, and PAU HANNA, an OUTRAGE V-20 with a 115-HP Suzuki. DON's DAUNTLESS and PAU HANNA were not catching up, but the big CONQUEST, who had gone wide to Starboard, was coming up fast. DRIFTWOOD must have had more speed available, but she just kept pace with the leaders, running about 45-MPH, and I bet no where near full-throttle speed.
I throttled back to a more comfortable cruise, as I don't really like to keep the throttle at wide-open for very long. A few minutes at over 5,700-RPM is enough for me, although I suspect the E-TEC wouldn't mind more time there. The three leaders went ahead, and I fell back with the back of the packers.
Based on my observations, I'd say the race would have been a very close match between CONTINUOUSWAVE, LUCKY TWO, and OUTLIER, all able to make 44-MPH or possibly a bit more. DON'S DAUNTLESS, with guest pilot John Raby at the helm, seemed to have run out of throttle at 35-MPH. PAU HANNA was also limited, possibly by her composite propeller. DRIFTWOOD seemed to be running at 45-MPH with ease, and I suspect there was more speed available, if needed.
It was a short duration, very informal speed test, but I was pleased with the boat speed we got from CONTINUOUSWAVE. Hitting 44.5-MPH was just about an all-time high speed for her. I think it was a combination of colder water, dry air, and a lighter-than-normal load of gear on the boat.
I invite the other participants to give their view of the race.
