The Dim Wastes
- Main hull 130ft x 25ft (widest beam)
- Outriggers 85ft x 10ft
- Footprint 140ft x 80ft
- 2 mounted silk sails, rigged as jib and spanker
- Main mast and forward stays deploy up to two of three kite sails up to 100ft overhead
- Each hull carries 1 forward-mounted gas generation engine, alchemically fueled.
- Each gas generator sprays hot gas out from the nose rib of the hull and back along both sides, disturbing nearby sand and creating a low density area of sand around the hull as the ship moves forward.
- Gas generators are turned on and off from either piloting helm. (control valves at both helms must be off for generators to shut off)
- Each engine can operate for several hours continuously after being loaded. Each full load of an engine is 3 fuel cells (9 cells total for all 3). Empty canisters are retained to be recharged later.
- The minimum performance of each engine is 4 hours per charge. The maximum performance of each engine is 12 hours per charge.
- Engine performance is determined by the worst of two checks – Craft:Alchemy to create the cells and Knowledge:Engineering to change the cells.
- There are a total of 90 fuel cell canisters on board. Whether full or discharged, these are stored in a specially armored locker near the stern of the ship. It can be accessed from ground level for speed in refueling, but the hatch is dogged shut by levers that must be disengaged from inside the hull.
- Fuel storage locker (detailed above): no extra space, filled with clip racks for fuel canisters.
- Forward stores: wide area of the interior hull that holds dry stores in netted bays along the bulkheads. A narrow passage through here leads to the bunk area below decks. Roughly 5 cu yds of storage space, or 900 lbs. This space is designed to be food and consumables storage for the crew.
- Outrigger stores (x2): narrow storage bin running the length of the interior portion of each outrigger. Each space is about 7cu yds of room, and can hold about 1100 lbs of supplies. These spaces are designed to be cargo storage.
- Fresh water tanks: each outrigger contains a single 100 gallon fresh water tank.
- Stripped carrying capacity (assumes no stored water, no crew or passengers, full fuel cell compliment): 8000 lbs
- Mission ready carrying capacity (assumes two people and belongings, food for them for 14 days, water tanks full, fuel cells full, no other cargo or passengers): 5800 lbs
- There is ample room on deck to tie down other gear or cargo. Total weight vs the power of the fuel cells to displace sand is almost always the limiting factor for this design.
- Keep in mind the above weights do not include additional people and gear. Calculations assume 275 lbs per person with all their belongings for a long journey.
- SeaChild requires two crew on watch, on deck whenever it is underway.
- One acts as pilot, steering the ship and controlling the tenser line of the kite sails from one of two pilot helms. Each outrigger has one piloting helm at its stern. Controls are mechanically linked for both (turning the tilling wheel at one will turn the tilling wheel at the other).
- One acts as rigger, tending to lines on deck and changing sail profiles as needed for the current wind conditions. The rigger must be free to move about the deck, but can take detailed direction from the pilot (i.e. only the pilot needs ranks in Profession:Sailor).
- Speed: 3-15 kts, 8 kts average
- Range: dependent on crew efficiency (320-1800 miles on all cells)
