The arc changes headroom, shoulder room, bench placement, heater mounting zones, end-wall details, ventilation openings and exterior water paths.<\/p>\n<p>Curved geometry can reduce unused upper-corner volume compared with some rectangular cabins, but shape alone does not prove faster heat-up or lower energy use. Actual heating behavior depends on internal volume, shell and end-wall assemblies, glazing, leakage, ventilation, climate, door use and the selected heater\/control system.<\/p>\n<ul>\n<li>Check the internal section, not just the exterior diameter.<\/li>\n<li>Confirm bench length, bench depth, heater guard zone and door swing on a drawing.<\/li>\n<li>Review where rain, snow melt and splash water leave the shell and reach the base.<\/li>\n<li>Do not infer timber species, stave thickness, joint detail or fastener grade from photos.<\/li>\n<\/ul>\n<\/section>\n\n<section class=\"hc-section\" id=\"usable-capacity\">\n<h2>Usable capacity vs marketed capacity<\/h2>\n<p>HACHILL publicly names BS13 as a 6-8 person route, BS14 as a 4 person route and BS15 as a 3-4 person route.
