Maybe it was cruisersforum.com that did it. Maybe it was the s/v Delos videos. Or Keep Turning Left. Or too much time spent walking around in local marinas. But, in any event, I bought a sailboat. It's an older 25' cruiser. Came with a trailer, and the whole affair will go down the road just barely within the size limits that keep it from requiring a special permit.
I didn't get it specifically for diving but I imagine I'll do some diving from it. One of my first to-dos is to add a ladder, since it only came with a portable one. Home port will be on Lake Pepin (best understood as a wide spot on the Mississippi downstream of St. Paul), at least at first.
At some point, I'm hoping to make some journeys to Lake of the Woods, Lake Superior, Minnetonka, Vermilion, and other area lakes. I've heard that Dryberry Lake in Ontario has fantastic diving, but it is extremely remote with multiple logistics and regulatory challenges, but I may try to get there.
