Maiden Voyage of the BRAtt
Early on the morning of October 28th, the BRAtt departed Point Roberts, Washington State bound for Seattle. Captain Ron Burchett and his able crew Alan Burchett and Ben Flodquist started out in 12 to 15 knot easterly winds and a two foot chop. With Boundary Bay abeam, the winds increased to NE 20 – 25, with four foot seas on the forward quarter. The ride was lively for this 28-ft tug, but with the heavy ballasted skeg the motions were very good with just moderate spray and no green water on deck.
Not Dead in the Water
While Z-Drive can still be considered a "revolutionary" design trait of today's tugboats, engineers aren't resting on their laurels. New technical standards being introduced are testimony to designers' creativity and imagination; and the functionality is improved, as well. The use of tugs with either Z-drive or VSP propulsion have led to much faster, safer and more efficient ship-assist operations, without fail, says Robert Allan, of the marine engineering firm, Robert Allan Ltd. In fact, he adds, some tug companies with Z-drive tugs have had insurance premiums lowered because of the reduced risk of them damaging an attended ship with better tugs. But in no way have tugs evolved to their highest achievable level. The birth of such innovative designs was not unexpected, says Allan.
