Elcano MaritimeCchallenge by south pass

[gilflo]

Hello guys

Here is my Elcano challenge via ocean and south land pass on a big Catamaran. There is no ISRU, the catamaran will be refill by air, by means of my Supertanker landing at waypoint 4 for refueling.

Here is the map with the waypoints, the goal being to achieve the tour as fast as possible. I should 2 refueling, no more.....

The catamaran is powered by 2 Turbo jet engines KE-90 "Dudley" from Mark IV system. It gives a 0.49 TWR and around 126000DV. Design with MK2 tank ahead of the engines gives a better top speed on water than cylinder tanks...don't know why.

Also the 6 wheels gears, despite bouncing on ground on launching, gives 20m/s more on maxi water speed than the 4 wheels gears....Another mystery, all gears being up inside the hull when navigating..!!!

Launch

Entering water

Turning to Waypoint W1. We are going west to keep day as long as possible. The catamaran is perfectly balanced on pitch axis and can support 4 time warp a full speed

Leaving cost at maxi speed around 110m/s or 220kts

Waypoint 1 reached at 195 kms

Waypoint 2

Waypoint 3: 1333km in 2H45

After more than 3H we see a small island on the left side

view from cockpit

Reaching Waypoint 4: 1991 kms in 4H4mns

We are going to look for the shore. Still 30mn fuel

Here is the coastline

Landing out of water

Mission aborted, the tanker is not operational....bad screens to see the travel time....

starting again soon, via East during night to cross the land passage a day rise, before a refueling in the south sea, the goal being to be as fast as possible for the circumnavigation
