There’s a few places to moor near the centre of Helsinki and, as you’d expect, a whole load of marinas around town. The one most recommended in Imray’s Baltic Pilot is a posh club where I’ve seen fit to put a red cross opposite. This is right next to noisy docks, completely at the mercy of the heavy chop from the many trip boats which zoom around the bay, expensive and on an offshore island.
Far, far better to keep going round the headland to the friendly, inexpensive HMVK club harbour. Here the rocky pontoons are also subject to a bit of chop, but not nearly as much so. This puts you pretty close to the centre of this interesting capital city, yet in a quiet part of town. It’s a short walk to all the sights and at high season, when all the local boats are off cruising, there should be loads of space. There seem to be only a few foreign cruising boats here. The posher ones mostly seem to choose the dodgy island club, complete with the disturbance from swell etc. The office of HMVK let me get post sent there and held it for me when I cruised off towards Russia for a few days when I had to get a new bit for a mobile phone. Definitely recommended.
