Our third road trip after Litchfield and Kakadu National Parks was to Northline Speedway to take in the sprint car action on their clay oval. We spent the last few days in Darwin at anchor in Fannie Bay before heading out across the Joseph Bonaparte Gulf to start the 1,000nm run to Dampier where we will exit Australia to cross the Indian Ocean for Rodrigues, Mauritius.

The HVAC drains on Dirona all run into the central gray water tank. Unfortunately some of the hose runs are not ideal, with almost no fall over substantial horizontal distances. Consequently, they plug easily. The worst offender is the salon system, which has two multi-foot sections with no fall at all. We redesigned the host run to minimize the top flat section, to put a slope into the lower section and to use much larger diameter 22mm rigid hose in the lower section that’s less prone to plugging.
Fisherman’s Wharf, where we purchased our diesel, does not have gasoline. We were almost empty from the Kimberley trip, so we dropped one of the portable deck tanks and took it out in our rental car to a filling station. When designing the boat, we were initially planning to have a fixed gasoline storage area built-in along with one for new and waste oil. We’re really glad we couldn’t find a solution to locating those, as having portable containers is much more convenient. Being able to get oil, gasoline and diesel all in the same place has been rare on this trip and we’re often having to transport oil and gas a fair distance from where the boat is moored.
Northline Speedway signs advertising Saturday night racing caught our attention as we returned into Darwin from our two road trips. Here’s the main attraction, 360 Sprintcars, lining up four-wide “World of Outlaws“-style on the clay oval. The speedway put on a great show and we had a super-fun evening there.
We had an excellent five-week stay in Tipperary Waters Marina, but it’s past time that we return to the wilds. Here we are pulling into the lock that maintains the sufficient depth in the marina while the tide swings through its 25.6 ft (7.8m) range.
After pumping out the gray water tank at anchor, we found a wet carpet at the foot of the master stateroom stairs and discovered that the gray water had mostly pumped into the bilge rather than overboard. The through-hull outlet had plugged and the pump built up so much head pressure that it actually sprayed water out of the emergency hand pump that’s in series with it. This unfortunately sprayed gray water throughout the area under the stairs where both pumps are mounted. The area was packed with spares, but fortunately none suffered any water damage as they were all in plastic boxes. Getting everything out and drying the area was a bit of a chore though.
The plugged gray water through-hull is well below the water line, so we couldn’t remove the hose to clear it. And we couldn’t dive the boat to due to the crocodile risk. James came up with a solution of closing the through-hull, removing the hose, and installing a temporary hose that extends above the waterline. He then opened the through-hull and used a vacuum in pressure mode to force the obstruction (probably marine growth) out of the through-hull entrance. This successfully cleared the obstruction.
