The Express 27 is an ultralight displacement recreational keelboat, built predominantly of vacuum bag moulding vinylester, S-glass, E-glass, Klegecell foam and a balsa core, with wood trim. It has a fractional sloop or optional masthead sloop rig, a raked stem , a reverse transom , an internally mounted spade-type rudder controlled by a tiller ...
In terms of model railway operation, gauge 3 is the largest (standard gauge) scenic railway modelling scale, using a scale of 13.5 mm to the foot. The Gauge '3' Society represents this aspect of 2 + 1 ⁄ 2-inch gauge railway modelling with both electric and live steam operation. Gauge '3' corresponds to NEM II scale, also known as "Spur II" in ...

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, but struggles in moderate winds.
Thus the scale and approximate prototype gauge are represented, with the model gauge used (9 mm for H0e gauge; 6.5 mm for H0f gauge) being implied. [2] The scales used include the general European modelling range of Z, N, TT, H0, 0 and also the large model engineering gauges of I to X, including 3 + 1 ⁄ 2, 5, 7 + 1 ⁄ 4 and 10 + 1 ⁄ 4-inch ...
EM gauge was an earlier attempt in the 1950s to improve the inaccuracies of OO gauge, with wider, more accurate track at 18 mm (0.709 in) between the rails, but still narrower than the correct gauge. The gauge was later widened to 18.2 mm (0.717 in). The UK-based EM Gauge Society exists to supports modellers of these standards. P4: 1:76.2: 18.83 mm
In addition to the descriptive steel grade naming system indicated above, within EN 10027-2 is defined a system for creating unique steel grade numbers. While less descriptive and intuitive than the grand names they are easier to tabulate and use in data processing applications.
