J/27

The J/27 is a keelboat built by J/Boats. It is both a weekend cruiser and a One-Design racing class with strict class rules. Designed with a low & heavy keel with a generous sail area, the boat gives good handling in both light and strong winds, though struggles in moderate winds.[1][2]

The J/27 is a Fractional rigged sloop designed by Rod Johnstone and built by Tillotson Pearson, Inc. between 1983 and 1992. 211 boats were built in total before being replaced by the J/80.

A large cockpit and open decks allows crew to move around easily and the Fractional rig means that sail costs are kept down.

The boat comes with a galley with a standard water capacity of 5 gallons and 4 bunks. Below decks headroom is 4.5 feet (1.4 m). The boat has an outboard engine placed on the transom (port side).

gollark: Rust can bind to C perfectly well, it's done a lot.
gollark: Well, then you can have a script interface the build systems together.
gollark: You can actually create, manage and build Rust projects with simple tooling which works easily and without horrible issues, and (almost?) every library uses the same stuff so you can interoperate trivially.
gollark: While strictly speaking you can use Rust and even `rustc` without `cargo`, having it as a first-class thing is EXTREMELY NICE.
