Clam - Linnhe Marine is one of the friendliest "marina's" on the west coast... I use the term marina very loosely, so long as you are not looking for luxury showers or fancy bars then you should have a great time.
Yeah the 'Marina' part made me chuckle, but since we're just looking for somewhere to launch and maybe flush thetrailer/engine down I'm not that bothered about airs and graces.
Going to be a busy old time: Anglesey at Easter and then up to Appin via the Clyde two week's later. Hope the old girl's up to it!
