Acrylic and polycarbonate are the two main materials used for boat windows and each one has strengths and limitations. The right choice depends on your vessel, conditions and budget. This guide explains the differences so you can choose the material that suits your setup.

Both materials perform well when installed correctly but choosing the right one also depends on how the boat is used. Acrylic suits most recreational vessels because it provides good clarity and holds its shape in sunlight. Polycarbonate is better for boats that face impact or heavy movement since it absorbs shock without cracking. Knowing the conditions the vessel faces helps select the material that offers the best balance of strength and clarity.

Acrylic

Acrylic holds its clarity for many years and resists UV well. It is ideal for windows where appearance matters. It can scratch more easily but can also be polished.

Polycarbonate

Polycarbonate is very strong and handles impact well. It is the better choice for high stress areas or larger panels. It may show wear earlier in harsh sun.
