Unlike some folks here, I enjoy these "best boat for..." threads, but we really need a few details about your needs, such as budget, to give you a good answer. How much can you spend? What are your top three priorities for a boat (for example: 1) storage 2) sailing performance 3) inboard motor). From your post, I'm going to assume you're thinking of a solo adventure.
Here's a few to consider if you're want shallow draft to really explore and gunkhole in the Bahamas, until we can narrow it down with a budget:
Gemini m105c - Popular, relatively affordable, simple shallow draft cat
Island Packet 26 - The original IP with a shallow draft has now become somewhat of pocket cruiser bargain
Seaward 26RK - Beachable little cruiser with vertically lifting keel and rudder
And how about this cool cat, the Tiki 30 (Wharram desgin) from Boatsmith
- She looks perfect for an adventurous romp through the Bahamas.
