A drying spell wasn't a bad idea, and J did know a few handy ones that they typically used on damp sails before folding them up and storing them away, so that they wouldn't collect mildew and mold before they were needed again. That said, he hadn't ever used one of those spells on anything with skin, and he wasn't exactly keen on trying out new magic in this situation. He hadn't been the best student at charms, and there wasn't anyone nearby to help the two of them if something went awry.

"Not one that I'd want to use on a person," he admitted, helping her off of his lap and onto one of the bench seats built in to the side of the sailboat. It was a shame that none of her clothes looked to be easily removed (and that doing so would probably leave her significantly underdressed), because surely drying out at least one article of clothing would at least help.

"Oh, wait," he said as an idea struck him. He shrugged his coat off of his shoulders and held it in one hand, fishing his wand out with the other. A quick spell saw it thoroughly dry, and he moved to drape it over her shoulders. "This should help, a bit."
