Earthrace Back Under Way After Repairs
San Diego, USA -April 9, 2007--Earthrace has now left San Diego and
is continuing on her round-the-world speed record attempt. The
unique wavepiercing vessel was involved in a collision off the coast
of Guatemala with an unlit fishing skiff, resulting in considerable
damage that has been mostly repaired in San Diego. She is now 800
nautical miles off the coast of California en-route to Hawaii, the
next refueling stop on her global circumnavigation.
According to Earthrace Captain Pete Bethune, the repairs were much
more extensive than initially anticipated. The gearbox and engine
mounts were replaced first, however there remained a series of
vibrations from various sources. The engine was realigned, the
propeller shaft straightened, and the Hytorq propeller rebalanced.
Bethune says "the hardest part was getting the driveshaft in and out
of Earthrace while she remained in the water. It was an extremely
challenging exercise that thankfully went well". The 3-inch diameter
shaft is 15ft long and weighs close to 400 pounds, so handling it
requires a team of people.
Earthrace Engineer Scott Fratcher says, "there is now a single
vibration left that we believe to be the Propflex coupling, which
joins the gearbox to the propeller shaft". This was found to be
off-centre by 10/1000 of an inch. The plan is to swap this for a new
coupling as soon as Earthrace reaches Maalaia, in Hawaii.
Meanwhile Earthrace continues her voyage across the Pacific with the
vibration ever present, but the crew believes it will be fine at
least until Hawaii. Earthrace is expected to reach Maalaia late on
Thursday night this week, local time.
