Applications of Marine Plywood

When selecting marine plywood, one must consider the application⁶ to ensure the plywood chosen will meet the specific performance requirements of the project. Here's how each type of plywood suits different applications:

Type of Plywood	Primary Applications	Advantages
Hoop Pine AA	Boat construction, high-performance boats, luxury yachts	Lightweight, durable, excellent moisture resistance
Gaboon	Boat interiors, furniture, cabinetry	Cost-effective, easy to process, aesthetically appealing
Pacific Maple	Boat hulls, outdoor decking, luxury furniture	High strength, resistance to impact, aesthetically versatile
Eucalyptus	Outdoor decking, marine-grade flooring, furniture	High weather resistance, rot and insect resistance

• Hoop Pine AA: Ideal for high-performance boats, including luxury yachts and performance racing boats, where strength, durability, and lightweight properties are crucial.

• Gaboon: Typically used for cost-effective boat interiors, cabinet making, and furniture production. It is also suitable for lightweight boat hulls.

• Pacific Maple: Often used in high-end boats where both strength and aesthetic appeal are needed. It is also popular for deck surfaces where impact resistance is key.

• Eucalyptus: Perfect for outdoor decks, boardwalks, and marine-grade flooring. It can withstand exposure to both sun and moisture, making it great for outdoor furniture and flooring.
