TRANSPORTING YOUR KAYAK
If you get a kayak (or canoe), your first challenge is to drive it home from the store. https://bluecordfishermen.com/getting-started-with-a-kayak/
There are many solutions but they depend on what type of wheels you drive. For those who have a pickup truck, the solutions are easy. For kayaks smaller than 12 feet, just lower the back gate and strap it onto the truck bed. 12 feet or longer craft need a bed extender. Below are several options from sears. More are available but for the money the simple Tee Extender works great for me. Best Christmas gift my wife gave me other than our little girl born on Dec 26th.
I have used this model for over 10 years and it is sturdy, adaptable and have years to go before I need to consider replacing it. Originally, I used it to transport a 14 foot canoe. Now I transport my kayak. One strap to secure the middle and a second one on the extender and I have never had an issue. Its easy to attach (two hefty pins with cotter pins and easier to load the kayak. I keep the extender stored in the back cab of the truck.
For driving in the dark, I duct tape a flash light to the back and tie on a orange flag. I have used my extender to carry my kayak on road trips that lasted over 4 hours and have not had any issues.
To use an extender, your truck needs a tow hitch. The first truck I had, I bought a hitch at U-Haul and installed it myself. The installation lasted over 10 years. My daughter scrapped this truck in 2018 and the hitch remained serviceable up to the end.
Roof Racks
If you do not have a truck, roof racks offer a solution. I have not used these but I did use a roof rack for my canoe. Heavy and awkward craft make getting it loaded on top of a car or mini van can present a challenge. I’ve done this myself, but may require more strength than you have by yourself. Roof racks have improved, but you still need the ability to lift the craft up on top of your vehicle. Notice they can be twice as expensive. A great reference for roof racks is:
My Recommendation is to use a pickup truck with a bed extender. This flexible option is useful for both fishing and carrying lumber and plywood.
