Yes, that's really needed. Sometimes, it's like impossible to get the boats from police spawn because boats are delicate and police/security blows them in just seconds. It will not be over powered or unfair in any way if we add one or two boats near the shore.
Moreover, in intention of getting a boat from police spawn, cops vs terror happens in rush and it usually results in spawnkilling which makes it even more unfair rather than adding boats near the shore is(who thinks it).
