Some suggestions:
"She's big, she's heavy, but you'll love her",
"She gets hot and then she moves slow and gentle",
"Get her moving and she'll get on top (of the waves)...
"The closer you get, the better she looks..."
"First you get on, then there is that "smell", its great!"
"Who knows what propells her, but she won't be held back!"
"The love comes in waves and sometimes you're overwhelmed by them".
"Don't fall on her, you could get hurt!"...ain't that the truth!!
etc., etc. LOL...
