The longer the boat the less it will sink into the water when not on plane, but the longer the boat the more drag created when on plane for top speed. Tunnels usually work better the longer they are but never had experience with one with that low of HP. I have had them with 25hp and I now have a southfork with a 40. My old tunnel was a 14 foot and it drafted a lot more water than my 16 I have now. But it was also a heavy made boat.
