This app enables you to design Classic Traveller Book 2 and Book 5 ships. If you register as a user, you will also be able to save those designs and print out pdfs.
There shouldn't be any bugs, but if you find one please report it. It's better to be told twice than not at all.Enjoy!
[COTI moniker: Matt123]
look and feel
The current style is intended to evoke a shipyard with battleship greys and rare use of color. I'm an engineer, not a graphic designer or artist and engineers like greys...
Thanks for the help!BillDowns, COTI
The app is written in Ruby on Rails with the front end in html, scss and jquery. The database is Postgres and the app is hosted on a free Heroku account (free Heroku accounts 'sleep' when not in use, which is why there may be a 20 second delay when you first "wake up" the app).
The browser has been developed on Chrome and tested on Firefox and Internet Explorer. It also seems to work on my partners mobile phone, not great but useable.
Sometimes what I thought were 'obvious' rules have proved not so obvious to others. Let me know if you find instances of this. CT errata endeavours to provide definitive answers. If it is new, Don (CT Errata author) generally prefers to discuss interpretation differences on COTI to get a range of views and then determine a ruling. Don does this as a volunteer in cooperation with Marc Miller. Kudos to both of them.Known interpretations which might be debated on COTI
- per n. Traveller uses per n, as in 1 Engineer per 35 ton of drives, in several ways. To mean per partial n (x/n).round_up and per full n (x/n).round_down, an example of which is 1 hardpoint per 100 ton of hull. See COTI.
- Medical crew. Have interpreted per n as round down.
- Engineers. Have interpreted per n as round up.
- Steward. Have interpreted per n as round up.
- bk5 Command. Have interpreted per n as 1 per 2000 ton, round down.
- bk5 Service. Have interpreted per n as round down.
- Service crew Uses 2 per 1000 ton rather than 3 per 1000 ton if the Ships Troops or Marines carried exceed 1 per 1000 ton. Troops carried as passengers are not considered.
- Gunnery crew The senior gunner for each weapon is assumed to be a Petty Officer. So a single Repulsor bay contributes 2 gunners to the crew count, not 2 gunners plus a Petty Officer.
- Crew USP Have adopted the original HG2 crew USP. After some debate several years ago a crew USP was adopted in CT Errata that is the ships tonnage / 1000 rounded up. This works for adventurer scale ships, but does not scale. For example a 30,000 ton Imperial Light Cruiser has a crew USP of 30 (which does not have a single letter code). Effectively making non-critical crew damage results irrelevant for any capital ships, reducing the effectiveness of spinal mounts.
- bk2 hardpoints and fire control. Have interpreted these per this COTI thread.
- Small Craft hanger cost Book2, covering ships up to 5,000 ton, does not charge for hangers and craft are carried at their own tonnage. HG charges 2000Cr per ton for all carried craft and ships over 1,000 ton must allocate 130% of the crafts tonnage. Have interpreted this as; no charge if the parent ship is 1,000 ton or less; otherwise carried craft occupy 130% of thier mass and cost 2,000Cr per ton.
- Fuel Scoops Fuel scoops are free and provided automatically to ships under 1,000 ton.
- Book 2 (p15) provides Fuel Scoops at no cost for streamlined craft. The Mercenary Cruiser is described in Broadsword (p18) as an unstreamlined craft capable of GG refueling, essentially it is partially streamlined. Consequently it is assumed Fuel Scoops are free for Book 2 craft. Unstreamlined craft obviously cannot use them anyway.
- HG uses Book 2 rules for 'smaller ships'. It is assumed 'smaller' is under 1,000 ton, meaning all craft get free Fuel Scoops if they are under 1,000 ton.
- Mixing Book2 Standard Drives and Book 5 Custom Drives This designer does not allow mixing the two types of drive systems. However recently a search for a canon referance or errata supporting this view has proved elusive, possibly meaning this is a Matt'ism.
