Keeping your boat cover securely attached to your trailer for storage or transport can be achieved in several different ways:
Bungee cords/shock cords, sometimes spelled (bungie cords), are favored by many boaters for their ease of use. The biggest complaint you'll hear is that they don't hold up in the sun. As they degrade, they weaken and stretch. My concern is a safety issue that not everyone considers: If the cord slips out of your hand when you have it stretched tight, it can pop you in the eye so be very careful!
Your average shock cord is usually a nylon-covered synthetic elastic core. Since nylon just doesn’t hold up well in the sun, it makes sense to have an adjustable hook end and one where the bungee can be easily replaced.
A better choice is the polyester-covered bungee since polyester holds up better in the sun. Solcor® is a favorite of ours, but is difficult to get in the US. It has a solid rubber core and a UV-treated polyester cover. The hook ends can be adjusted and used again on future replacement cords.
We spotted this lifetime warranty bungee that we like and believe it will serve you well!
Rope tie downs are frequently used by boaters, especially when the boat is being towed, so it makes sense to buy rope that is going to hold up year after year. Polyester is the longest lasting, toughest rope. It will outlast nylon and polypropylene. Our favorite is Neobraid. This braid will take years of sun and abuse without giving up. It will not kink, twist, or fray, and it also resists mold, oil, and stains. For your average boat application, use either a #6 = 3/16” or a #8 = 1/4”.
Boat Straps made with 1” webbing coupled with quick release buckles are easy to use and are a personal favorite. We always supply this type of tie down when we make custom covers. They are even better if they are completely removable from the boat cover. It makes life so much easier when they don't catch on the boat while handling your cover.
So what type of webbing should it be?
Here is a list of webbing materials commonly used for boat tie downs beginning with the longest-lasting. It is exceptionally hard, if not impossible, to find the polyester straps online. If you want them, you would need to order them from us or another custom shop.
Keep an eye on your straps as they age and replace them when they begin to show wear.

Boat covers have to be cinched in some fashion to the boat itself. There are multiple ways to do this. One is to have rope sewn into the hem of the cover and tie it to itself. If you have a rope-style cinch system on your boat cover, use the same type of knot pictured above for cinching the cover to the boat.
For an even more secure cinch, a second option is to try a rope lock tie down such as the Carolina Rope Ratchet®. When you pull this rope lock tight it won't slip, so you can continue to tighten it and then press a button to release it. We like these because they make life easier and can be pulled super-tight.
A third way to cinch your cover to the boat is with webbing in the hem along with the use of a webbing ratchet such as this Pro-Grip® ratchet. If you use webbing and a ratchet to secure your boat cover, it should have it's own little storage boot or another creative way to protect the paint on your boat from the metal ratchet. They are clunky and can damage your boat without protection.
On boats that need additional tie downs while in the water, I've seen boaters attach 2 liter soda bottles filled with sand or water to the webbing tie down straps which adds weight to the cover. This can be effective, but the appearance is obviously less than elegant.
That's completes our run down of boat cover tie down systems. We hope that with this information, you will now be able to choose the system that's right for you!
We'd like to help you find a solution! You just might be able to help someone else trying to solve the same problem. Please include your email address, I may choose to contact you directly with an answer.

I have a cover that uses straps with buckles would like to replace them with bungees but can’t find anything to leave on the trailer to hook to! Any ideas? Thanks
The plastic buckets break and don’t last and take forever to put on
How can I tie down a boat cover by attaching it to the boat when it is on a boat lift? Can't attach the cover to the lift. I can't run the cover straps under the boat..
The boat has to be able to float up off of the lift when the water level rises (dock lines are also attached so it can't float away)
Can we replace boat cover cinch cord with bungee cord?
Is there an easier way to cover the boat at the dock without having to mess with pulling the ropes to tighten?
