Sandown is good for landing as the fish and chip shop is just up the high street from the sea front. Makes an good place to stop whilst decompressing between dives. There is a pier but the nobber that runs it wants a fortune to moor up for a stop and the barnacles aren't going to do your toobs much good. Instead we drop the anchor 30 yards off the beach and drift back on it.
Bembridge isn't very welcoming
and watch the tide if you go in.
Nice beach just round the corner from the Needles or even freshwater bay but only if its flat calm and watch your speed and the rocks. Ventnor has a new little harbour just don't let the smell put you off and the harbour master very friendly.
There is another little harbour/landing stage between Ventnor and St Caths but there are underwater blocks to break the surf just below the surface
so tread carefully.
With 90 hp you are going to need bigger fuel tanks even if you refuel at Yarmouth. Loads of stuff about fuel tanks on here, spend an evening searching.
