Most sailors switch to engine at sailing speeds below 6 knots especially when on passage. One side Distance 30 miles. I originally thought it was plugs when I changed them it would run good.
Instead because the water is moving the boat moves from A to C This stretch must be 5 4km 125km since 15 min. If I let it cool off for a few mins it will run well again for a few mins. 25 16 1 9 16.
For it multiply both sides by 2u-6u6. Total time taken 4hr 30 minuts 45 hr 92 hr. In decades past cigarette boats or rum-runners were motorboats designed for fast travel.
3176mph 511 kmh was the fastest boat speed ever recorded. You will get 45u6 45u-6 --- 90u 0 --- 0 --- u-9u4 0 --- The only positive root is u 9.
