Q: Where can your yachts safely travel? Are they designed to handle big seas? What should I be aware of in comparing these boats to other power catamarans or mono-hulls. A: Anywhere! These boats are true Expedition style passage makers and are capable of open ocean transits. Unlike many power catamarans that may really be most suitable for day and coast wise use, the Pacific Expedition Yachts are designed and built for the yacht owner who has some serious use and adventure in mind.
