There are many options to manage bringing a dinghy along with you on a sailboat. You can tow it, store it on deck, or you can hang it from the stern of the boat on dinghy davits or a stainless steel arch. When we bought Wild Horses, she came without davits or an arch so we chose to tow the dinghy whenever we sailed. Compared with storing the dinghy on deck, this gave us easy access to hop into the dinghy and head to shore for some exploring and walking the dog. This system worked great but it also left the dinghy vulnerable to theft (cut the tow line, get a free dinghy and motor!) and also slowed the boat down.
