Let’s Talk About Raymarine ST300, Thru-hull Shorty
The Raymarine ST300, Thru-hull Shorty is a compact speed sensor designed for boats where space is at a premium. This sensor, manufactured by Raymarine, offers a cost-effective solution for measuring a boat’s speed through the water. Its short thru-hull design makes it ideal for vessels with limited headroom, ensuring accurate readings without compromising on space.
I needed a reliable speed sensor for my sailboat, but the shallow draft and limited space near the keel made installing a standard thru-hull sensor impossible. The Raymarine ST300, Thru-hull Shorty seemed like the perfect answer. Its compact design promised to fit without requiring major modifications to the hull.
Upon unboxing, the ST300 immediately impressed me with its solid build quality. The plastic housing felt robust and durable, capable of withstanding the harsh marine environment. The compact size was also a huge relief, confirming that it would indeed fit in the tight space I had available.
Compared to other thru-hull sensors I’ve used, like the Airmar ST800, the Raymarine ST300, Thru-hull Shorty trades some advanced features for a significantly smaller footprint and lower price point. While the Airmar offers more sophisticated data and is a great product, the ST300 prioritizes simplicity and ease of installation, which was exactly what I needed. I chose the ST300 primarily because of its compact size and reputation for reliability in basic speed sensing.
My first impression was one of cautious optimism. The build quality seemed good, and the size was perfect, but I was eager to see how it would perform once installed and in the water. I was excited to finally have a working speed sensor on my boat, a feature I had been missing for far too long.
Real-World Testing: Putting Raymarine ST300, Thru-hull Shorty to the Test
First Use Experience
I installed the Raymarine ST300, Thru-hull Shorty on my 27-foot sailboat in a local marina. The installation process was straightforward, requiring only basic tools and some marine sealant. Once launched, I took the boat out for a test run in calm bay waters.
The ST300 performed admirably even in choppy conditions. The speed readings were consistent and seemed accurate when compared to GPS data. The sensor responded quickly to changes in speed, providing real-time feedback.
The ST300 was remarkably easy to use, requiring no complicated setup or calibration. It integrated seamlessly with my existing Raymarine instruments. There were no initial issues or surprises, which was a pleasant change from some of my previous marine electronics installations.
Extended Use & Reliability
After several months of regular use, the Raymarine ST300, Thru-hull Shorty has proven to be a reliable and valuable addition to my boat. It has held up well to the rigors of saltwater sailing. There are no signs of wear or corrosion.
The plastic housing still looks as good as new. Maintenance has been minimal, requiring only occasional cleaning to remove any marine growth. The smooth, low-profile design helps minimize fouling.
Compared to previous speed sensors I’ve used, the ST300 stands out for its simplicity and dependability. It consistently provides accurate speed readings, making it easier to navigate and optimize sailing performance. The unit’s ruggedness and ease of maintenance have far exceeded my expectations.
