Tesla's website says the 6-feet-8-inch board should fit inside a Model S, Model X and Model 3. The surfboards and feature Tesla logos on both sides. The board is reinforced with carbon fiber while the bottom uses two layers of 4-ounce cloth. The fins are not included.
Although the board went up on Tesla's website over the weekend, it appears to have sold out in less than a day. If you scored one, expect a wait of up to 10 weeks for delivery. If you missed it, keep an eye out on eBay. Just be prepared to pay a hefty markup.
