The simple answer is that it depends on the whips. Whips don't come in a one size fits all format. If your whips are rated for the weight there is no doubt in my mind your boat will be fine.

I have used whips for years, mainly because it was just to much work to put my entire U shaped dock in, mainly because finding help isn't always easy.

If your whips are two small for the application, you boat will not always be fended away from the dock, and the could potentially snap. I would call someone like Center Harbor dock, that sells whips, to come out and take a look at what you have, and make sure it is adequate.
