As for a rope choice, Nylon is the clear favorite due to the fact it is elastic and relatively strong,. Along with the rope, you should also have a smaller amount of chain between the rope and the anchor. This chain will keep your rope from rubbing against the seabed and also creates the optimal angle between your rode and the seabed. The general rule of thumb is that you want approximately 1' of chain for every 1' of boat.
So a 30' boat would want 30' of chain. However, often certain constraints such as weight and locker room will not allow this ideal chain amount so in these situations you should have at least ' of anchor chain for the reasons mentioned above. The reason for the different requirements is that, in theory, by having 1 foot of chain for every 6 feet of rope, an optimal angle between the rode and the seabed will be achieved.

For a bigger boat in bigger winds and with big waves, you should use more. If you plan of leaving the boat unattended for any amount of time ensure there is plenty of anchor rode let out.
