From the author's README on Thunderstore

Bumps up the board and trucks by 12% for those who like bigger boards.

This is just a popsicle, but it is probably a good starting point for anyone who wants to try making bigger shaped boards.

The wheels are repositioned to match the widened trucks.

Installation

Install WideDeck12 from the ReSkate launcher's Thunderstore browser. You can also download the package and use Mods → Install .zip in the launcher.

Enable WideDeck12 in the mod list if it is not enabled automatically.

Requirements

skate.
The normal ReSkate release; no custom build is required.

Install WideDeck12

You need ReSkate and your own copy of skate. on Steam.

Open ReSkateLauncher.exe and go to MODS.
Search for WideDeck12 and click install. The launcher also installs anything it depends on.
Press PLAY. In game, the MODS tab of the ReSkate menu (Insert) turns it on and off.

Or install it by hand: download the .zip and drop it on the launcher window, or unzip it into its own folder in Mods\ beside Skate.exe.

Maps show up in the ReSkate menu's level list. To join a server running a custom map, you need the same map installed. If the game won't load after installing, see known issues.
