Deck (ship)

The main purpose of the upper or primary deck is structural, and only secondarily to provide weather-tightness and support people and equipment.

The actual floor surface is called the sole; the term 'deck' refers to a structural member tying the ship's frames or ribs together over the keel.

A traditional wood deck would consist of planks laid fore and aft over beams and along carlins, the seams of which are caulked and paid with tar.

The wash or apron boards form the joint between the deck planking and that of the topsides, and are caulked similarly.

The difficulty in metal construction is avoiding distortion of the plate while welding due to the high heat involved in the process.

Teak wood is a popular choice for modern yacht decking due to its natural durability, water resistance, and aesthetic appeal.

Known for its ability to withstand harsh marine environments, teak requires relatively simple maintenance while providing a classic, luxurious look.

Its natural oils make it resistant to rot, pests, and UV damage, and over time, it develops a silver-gray patina.

Alternative yacht deck materials have grown in popularity due to their affordability, lower maintenance, and environmental benefits compared to traditional teak.

Bamboo is durable and environmentally friendly but requires proper treatment to ensure resistance to moisture and rot.

- Eva foam: Common on racing yachts, these materials are practical, lightweight, and easy to implement.
