Some pro fishing kayaks come with pre-installed tracks and/or heavy-duty tracks, such as NG10, NG10 MKII, TRITON, KRONOS, NG11, PK12, PK14. For standard kayaks, tracks and heavy-duty tracks are not pre-installed, but there are designated locations and flat surfaces on the kayaks that allow for the installation of tracks and/or heavy-duty tracks. Examples of kayaks without pre-installed tracks include NG09, NG1+1, NG07, Osprey, Eagle 12, Eagle 12 Pro, Puffin, and Puffin Pro.
