Now is she asking for Luke's character because he's got reach or~....

She's asking because Luke's character can literally stretch himself enough to grab onto the roof of a building from ground level, while everyone else is a standard human for all reaching purposes (don't ask about strength). So if any of the other characters on the Going Merry tried to catch her, she would either have to be within a few feet of making it onto the ship on her own or both of them would end up in the ocean (since the human catcher would have to reach out beyond the point of balance or jump away from the ship to catch her), while if Luke tried to do it, his rubber form would let him catch her mid-air and reel her onto the ship without harm.

Pretty sure Luke's reach score is "yes"

I want to aplaud that comment.

Important to have a back up idea.
