A Sanger v215 should be able to support a Switchblade without much problems. We have not installed one on that particular boat, but I am familiar with Sanger boats and their hull design is strong enough to support one, no question. As long as it will fit below the swim deck and there aren't any problems with misc things such as exhaust placement or tim tab setups it should fit. If you have a Hydraulic trim tab it will probably have to be removed to install a Switchblade. One thing I do have to advise is that adding a Switchblade to your boat will void any remaining hull warranties - typically not a major concern, but something you should be aware of.
We have installed and worked on more Switchblades than anyone in the industry except for Switchblade themselves. Any of my guys here would be happy to help you with any questions you have. A Switchblade can be a phenominal investment for wakeboarding and surfing depending on your needs and what your goals are.
Good luck and keep shredding!
