简短问答
这类交通工具要看哪些本地机构或走廊规则？
先看本地视角中的型式认定、营运许可与枢纽——不要假定一份全球清单。
Is this a buying guide?
No. Tool-Lifes /vehicles is an educational atlas. It explains history, systems and culture without affiliate rankings.
Are the scores official?
No. The six scores are relative editorial 0–100 marks across the 48 types on this site.
Where do the photos come from?
Lead images resolve from Wikimedia Commons via Wikipedia titles on the English masters, with licences recorded on the credits page.
Why metric units?
Metric is the default. Regional notes (US customary, local brand culture) appear in culture and market chapters.
How is this different from a wiki article?
Each type gets seven fixed-depth chapters, comparable scores and cross-type labs — structured for browsing, not a single freeform page.
安全运行Tugboat需要按相同顺序追踪能量、信息与机械流。
CBTC、ERS等通用缩写保留，并在上下文中解释。
原理
就Tugboat而言，Bollard pull vs HP
就Tugboat而言，Hull form and prop nozzle efficiency convert shaft power into measurable pull.
就Tugboat而言，Indirect escort force
就Tugboat而言，Skeg generates yaw moment on ship without physical contact at speed.
就Tugboat而言，Pivot point geometry
就Tugboat而言，Push point relative to ship's pivot controls turning moment in locks.
就Tugboat而言，Line snap-back
就Tugboat而言，Stored elastic energy in hawsers kills bystanders—exclusion zones are mandatory.
就Tugboat而言，Ventilation loss
就Tugboat而言，Air sucked into props drops thrust just when full power is commanded.

运行步骤
02 就Tugboat而言，Make up tow/push
就Tugboat而言，Approach slow; mate fenders; pass line or establish push contact.
03 就Tugboat而言，Execute move
就Tugboat而言，Short bursts of power; coordinate rudder and tug thrust for lock entry.
04 就Tugboat而言，Hold & check
就Tugboat而言，Maintain tension against wind and current while lines are made fast ashore.
05 就Tugboat而言，Cast off
就Tugboat而言，Release in agreed order; clear prop wash from pilot ladder zones.
06 就Tugboat而言，Stand down
就Tugboat而言，Coil lines, flush 发动机s, log bollard pull tests per class schedule.
硬性极限
就Tugboat而言，Certified bollard pull
就Tugboat而言，Contractual pull trials define usable thrust—not nameplate kW alone.
就Tugboat而言，Snap-back zone
就Tugboat而言，Deck hands must stay out of line snap envelopes during tensioning.
就Tugboat而言，Fi-Fi rating
就Tugboat而言，Fire monitor capacity must match escort contract tier.
