The Yakima BowDown Boat Rack is an easy-to-load, padded, and quick-to-install option that works on a variety of cars. However, there have been many user reports of a lack of a secure connection with round bars, with the kayaks slipping during use when driving at high speeds. Unfortunately, the lack of stability make this a questionable choice for carrying kayaks.
The Thule Hull-a-Port Kayak Carrier is a highly-compatible carrier that works with most crossbars, but unfortunately has some reports of the mechanisms failing. Reports of the internal lock failing, the screws loosening, and arms getting loose over time diminish confidence in this product.
The Thule Stacker Kayak Carrier is a high-quality, durable, and versatile option that is best suited to carry two kayaks securely and safely. The possibility to carry no more than two kayaks may deter some groups from purchasing this carrier, but the ability for any Thule rack to attach to one another makes it easy to add another stacker.
