AS a former dealer and owner of a Precision 15, it in many ways has more room than longer daysailors and is built well. Heeling no more than 12 degrees, you will go fast as there is less wetted surface or friction when sailing flatter vs. heeled way over. Plus you do not want to scare anyone particular the better half. I am not sure if the main is a bolt rope or sail slugs but if bolt rope, convert that over to sail slides. Also add a topping lift which I also used to aid holding the mast up after raising the mast tying it up forward which allowed me then to attach the forestay.
In addition I added at the end of the boom an eyestrap or something which to attach a twist shackle shackled to a small boat double cheek block with a V jam used or seen on small boat boom vang which I threaded in a manner the topping lift thru which then I could lower or raise the boom quickly.
Most mfg. reps I never trusted except for a few. Bart Blei who is the sales manager I found over the years to be very truthful, honest, imformative, helpful and so on with customers as what was reported back to my along with my experience with him too. I very rarely trust reps but he is one that broke the mold. Call him
As for the boat cover, that company does excellent work as I ordered them from them in the past to include my own personal boat. Get a light color as heat builds up underneath in the hot sun. You may want to add vents.
