A custom cover is a great investment to prolong the beauty and life of your boat some people consider boat covers an accessory. nothing can be further than the truth.. Shoretex custom boat covers feature a draw rope sewn within the cover’s hem for cinching the cover tight against the boat. loops are also sewn every few feet throughout the hem to provide tie down locations which allow the cover to be anchored in place.. When ordering a boat cover, you will need to decide whether you want a "fitted cover" or just a rectangular cover that you can tie over your boat (like the one shown above). in order for us to make a fitted cover you will need to provide very detailed drawings to ensure that it is sized correctly..
