What's new in WireEngine
Every notable change to WireEngine, written for the people who use it. The newest release is at the top. Version numbers follow semantic versioning, and a "beta" release can still change before it is final.
[0.9.0-beta.0] — 2026-11-04
The first beta. WireEngine designs the DC electrical system of a boat (RVs and vans in preview), checks it against ABYC E-11 as you go, and turns it into a complete document set you can hand to an installer or a surveyor. Every number in it is worked out from your design or cited to a source.
Design
- Start from a blank design, from one of six reference designs (including a 24 V catamaran), or from a plain description of your boat.
- Add batteries, chargers, loads, switches, buses, fuses and wires in any order. Nothing has to be finished before anything else.
- Wire gauges and fuse ratings are worked out from each circuit's current, length and voltage, and worked out again whenever a value changes. A "What changed" list shows what moved and why.
- Every value shows where it came from: a manufacturer's document, a measurement on the boat, an ABYC table, a calculation, or "not confirmed yet". A value worked out from others never ranks higher than its weakest input.
- A fuse the checks propose is marked "recommended, not installed" until you say it is on the boat.
- The design assistant answers questions and proposes changes, but it never sets a safety value such as a wire gauge or a fuse rating.
Checks
- Live checks against ABYC E-11: fuse placement and rating, wire ampacity, voltage drop (3 % for critical circuits, 10 % for the rest), bilge pumps that must bypass the battery switch, a single negative bus, wire colours and more.
- Each issue names the section it comes from and says whether it is a "shall" or a "should".
- A check that cannot run yet says so and names what it is waiting for. An unfinished design never reads as clean.
Documents
- The wiring schedule, the wiring diagrams (a sheet set with an index, legends and conductor tables), the bill of materials, the commissioning checklist, the handoff brief, the surveyor appendix, the design guide, the settings register, the vessel passport, inventory and spares, and the owner's manual.
- Download everything as one package, print the sheet set to PDF on A3 or Letter, download any sheet as an SVG, or download the set as an editable draw.io file.
- Every document carries its revision, the number of open items, and a line saying it is design help, not an inspection or a certificate.
Aboard
- Measure each run in feet or metres on your phone. The worksheet keeps your place and moves to the next run when you save.
- Inventory with storage areas on a deck plan, suggested spares for the fuses you have installed, maintenance intervals and engine hours, manual search, and a troubleshooting helper that points to your manuals.
Accounts and help
- Accounts with email confirmation, password reset, a download of all your data, and account deletion. Organisations for professionals, with invitations and roles.
- A getting-started list on each project's Overview, a glossary, and help pages on reading your documents, measuring aboard and what WireEngine checks.
- Send feedback from the Help menu, with a screenshot if you want to attach one. This page lists what changes in each release.
Known limits
- RVs and vans are a preview. They are checked against marine rules, and no RV-specific code is checked.
- Prices are not live during the beta.
- WireEngine needs a connection; offline use is not supported yet.
