CHS charts are generally superior for any marine navigation. whether in a large ship or on a paddleboard, because maps for landlubbers provide neither water depth nor current direction information, not to mention specifics about each aid to navigation, traffic lanes etc.
It can be helpful to have both topo maps and marine charts – complementary information is often useful because marine charts lack land details that are relevant to paddlers.
