The Linda Mae is not wheelchair accessible. However, I'm sure the crew would be glad to help. The problem is that the benches may be too close to the railing to accommodate a wheelchair. That being said, I'd call them and see if there is anything they could do.

If you don't have a boat and don't want to spend $400+ on a private charter, the Linda Mae is a great alternative. And Roger's (one of the first mates) running commentary is priceless. Good luck.
