槳的尺寸、形狀以及角度
The blade is the part of the paddle that you dip into the water when you’re taking a stroke. The size, shape and offset of the blade all affect how the paddle performs.
槳面是你在划行時放入水面的部分，所以形狀以及角度會影響你划行的形式。
Blade Size
There’s no hard and fast rule for determining exactly what size paddle blade you need. Over time, you’ll probably develop a preference for a certain size blade based on the type of paddling you do and other factors, like your body type.
選擇槳的方式沒有最佳途徑，你必須經過多次的使用經驗、個人習慣甚至是你的身型來決定最適合你的槳。
But, if you’re brand new to SUP, use this guideline: The larger you are, the larger your blade can be. This is because bigger paddlers typically have the strength to pull a larger blade through the water. An easy way to compare blade sizes is to use the blade surface area measurement (given in square inches) that is provided on REI product pages.
但如果你是SUP新手，以下有幾點建議：身型越大的玩家通常力量也比較大，可以使用較大的槳。
Here are some approximate surface area recommendations based on body weight:
以下是體重以及槳面對照圖：
Small/medium body types (less than 150 lbs.): 80–90 sq. in.
小型/中型體型（低於68公斤）：516–580 平方公分
Medium/large body types (150–200 lbs.): 90–100 sq. in.
中型/大型體型（介於69–90公斤）：580–645平方公分
Large/X large body type (200+ lbs.): 100–120 sq. in.
大型體型：（90公斤以上）：645–774平方公分
With these recommendations in mind, here are some additional things to think about:
有了以上的體重對照，還有以下幾點建議：
• Large blades are more powerful: A large blade moves a lot of water, which allows you take powerful strokes to get your board up to speed quickly. If you’re a SUP surfer, for example, you might like a larger blade (100–120 sq. in.) that will allow you to take a few powerful strokes in order to quickly position your board to catch a wave.
大型的槳划行相對更有力量：槳面的大小會影響划行的力量，也可以划行的更快速，如果你使用立槳衝浪，大面積的槳面也可以讓你快速的調整位置追浪。
• Small blades are more efficient: A small blade moves less water with each stroke, but it’s easier to pull the blade through the water than a larger blade, which means you use less effort with each stroke. A blade in the 80–90 sq. in. range might be an advantage if you’re a SUP racer or long-distance tourer and you want to preserve energy for the long haul. A small blade is also a better choice if you like to paddle with a high cadence or if you need to be more gentle on your joints and muscles.
小型的槳更有效率：單次划行的能量低於大型的槳面，但是也較容易將槳抽離水面再進行划行，划行可以減少力量的消耗。介於516–580 平方公分槳面的槳適合衝浪、競速以及中長時間的玩家，也易於節省體力。小型的槳也適合快節奏的划行，對於關節肌肉負擔較小。
