I did this last Summer from Stapleford. On leaving shoreham I told them my plans and they asked me to report at Selsey Bill, they then passed me on to Solent who after squawk was indented allowed me through no problem . I did climb to about 3500 feet if I recall on crossing the water to reach Newport to give max opportunities over the water . Came back after needles to Sandown then routed Goodwood. Lovely trip .Enjoy .
