We took our daughter into line, but decided it was not possible after watching the boarding process.
She has cerebral palsy, spastic squad/mixed tone. When she gets excited, she has high extension tone, especially in her legs and trunk.
She is about 5 feet tall and about 80 pounds.
This picture is the unload area, which is right down the track from the loading area. The front of the boat is toward the CM in the reed costume. So you transfer in to the left and out to the right.
I was told they do have a transfer board available on request, but did not see it (it might help someone with paraplegia, but we didn't feel it would help our daughter).
To get into the boat, you need to get over the side, then the seat is down about 8 inches from the side. The floor is down about another 8 inches.
The boat is the same boat as the former Maelstrom had. We did put our daughter in that a few times in the past when she was smaller and lighter.
It was not easy - one person got into the boat and stood up to receive her. The outside person handed her over the side of the boat. The hardest part was getting high enough to get over the side.
If she bent more easily, I would have probably supported her on the side in a more 'bent' position to get in.
Getting out was harder - again, one person in and one out - and the harder part was getting over the side.
The side of the boat is not very wide, so not a lot to balance on if you plan to balance on the side and swing legs over.
