/**
 * Travels from Lumbridge to Catherby by boat. Intended for use by low level accounts.
 * Death is possible.
 * <p>
 * Requirements:
 * Start script logged-in at Lumbridge (or anywhere along the route).
 * <p>
 * Inventory (Optional):
 * 60 gold coins
 * <p>
 * Parameters (Optional, space delimited):
 * "thieve" - Enables thieving Men for coins.
 * "banana" - Enables picking Bananas for food.
 * "ardougne" - Enables stopping at Ardougne instead of Catherby.
 * <p>
 * Notes:
 * e.g. "banana thieve ardougne" will thieve for coins, pick 10 bananas, and stop script at Ardougne.
 * Any extra coins (< 10gp) and/or bananas will be dropped upon arrival at destination to clean-up inventory.
 * <p>
