Measure the full vessel envelope, including beam, height, trailer or cradle, and any mast or fittings that remain in place. Then add working room for technicians, access platforms, removable parts and tools. A narrow aisle may be sufficient for storage but can become a bottleneck when several people need access to different sides of a boat or a major component must be removed.
Door placement should follow the route used to bring boats in and out. Think through approach direction, turning room, external staging and where a vessel waits while the repair bay is occupied. If the yard uses hoists, lifts or cranes, confirm clearances and equipment loads with the equipment provider and the building engineer. A building should not be presumed to support suspended loads simply because the interior is open.
