You need a spaceship that takes less than 14 years, so 15-3-3-1-1-1 is not fast enough (15.7yrs). Do one Hab Module, one LS Module and one SP Module, then add 4 of each Component (propulsion and fuel), then add Structurals over 15 till the "*" disappears next to the listing. If that is not fast enough, go to 5 of each Component, then add more Structurals. I don't have a list of configs for each of these, but I do remember the "fastest" ship: 33 Structural, 8x2 Components (propulsion plus fuel), and one of each Module gets you there in less than 6 years, but only 100 points for the ship (one Hab Module). A 39-8-8-4-4-4 gets you there in less than 7 years, with 400 points, at the cost of 15 more spaceship parts. Have you got a large empire?
