Many congrats Graham and Mandy
I bought my 331 in 2018 and am still in love with her.
My advice is to go slowly and enjoy all the beautiful harbours / scenery on the way.
I have only done the passage Dartmouth to Pwllheli – but I did visit every harbour in between!
I have met all the Harbour Masters on the way ( I am doing a charity challenge to meet them)
I would strongly recommend calling in at these harbours which all have good facilities, good shelter and outstanding Harbour Masters:
Newlyn (rather than Penzance)
Bristol – if you have time!
Cardiff – ditto
If you would like any more advice please phone me 07817845775 or firstname.lastname@example.org
