i need to find some good spots to launch on the east coast too but having a rib on a trailer makes it more awkward.
Whitby has the nicest slipway, wide, good gradient and accessible for 90% of tidal flow. good parking too. furthest from me to drive too.
Scarborough is ok but the slip is right there for the grockles to gawp as you tallywhacker it up.

. shite parking too.
Northbay, Scarborough is mainly a jet ski thing and very exposed to waves.
Bridlington, nowt in the harbour so you need to do a beach launch further down which depending on the size of boat is most certainly a tractor job.

plus can get rough in the surf over the shingle beach.
South landing, Flamborough is a life boat slip so you need permission from the rnli station plus its onto sand strewn with rocks. ok for kayaks and small sibs but owt on a trailer is a reet twat! plus its one hell of a walk back up the hill to the car park at the end of the day.
Filey is direct on to sand so a good tow vehicle is a must plus it being quite a flat beach means a long way out to get depth under the hull to float off the trailer and drop the engine.
all of the above want mucho mulah to launch and park too!! robbing bastards!!
the east coast is moderately poo for launch sites.
with a smaller SIB (2.6-3.2m) ur ok as you can just wheel it about on transom wheels so can technically drop in anywhere but summat wi more beef and, well, it kinda sucks!!
