It's... graceless. Martin has to try hopping twice before he gets enough of himself onto the raft to grab for the mast and use that to wriggle up. It also causes the raft to rock more than he wants, but he's hopeful the others will be able to stay on. When he's finally up, he's panting soft, kneeling on his hands and knees.

"O-okay. Okay, I think I can... paddle." Just hand him an oar and point him in the right direction! He grimaces slightly, looking over at the others. "Sorry. That wasn't quite as easy as I thought it was going to be." But it's over, they're on, and they have a destination. Onward!
