Your trailer sounds like it will work just fine based on the dimensions and weight you gave. I simply recommend putting the bunks up as high as possible for your initial loading onto the trailer because the underside of your boat from my research has a deep groove on each side where those bunks sit. Make sure the bunks are in the depth of the groove and the outside bottom of the groove is either over the fender or inside it. If you need taller supports you can adjust the height. We have the CE Smith Double U-Bolt Bolster and Swivel Bracket Assemblies - Galvanized - 16-1/4" - Qty 4 # CE10196G-4 which are the tallest we carry. I've linked a page to all your options. You may want to consider using a keel roller like CE Smith Deep V Keel Roller Assembly for Boat Trailers - Galvanized Steel/Black Rubber - 5" # CE10401G to help center your boat. Many will also choose to use CE Smith Post-Style Guide-Ons for Boat Trailers - 40" Tall - White - 1 Pair # CE27620.
The width of your boat can be wider than the trailer as long as the weight is supported. It is not uncommon for the boat width to be wider than the trailer frame.
