About the harbour
Automatically summarised text: Automatically summarisedvia web search · 28 September 2026Flottviks Båthamn is run by Märsta Båtklubb and lies at the innermost point of Flottviken by Sigtunafjärden in the northern part of Lake Mälaren, in Sigtuna municipality. The facility is a sheltered club harbour with berths for nearly 200 boats spread across five piers, and a breakwater extends almost a hundred metres out from shore.
A slipway of concrete and timber at Flottvik allows larger boats to be launched, but the slipway lies behind a gate on the club's grounds, so you need to contact Märsta Båtklubb for access. Parking is available outside the gate. A speed limit of 3 knots applies throughout the harbour area.
The piers are equipped with electricity and water, and the water from the taps is fresh water from the club's own well. For launching and hauling out, the club mainly uses a Sublift 12T travel lift, while smaller boats are lifted using a tractor.
The harbour is close to fishing on the fjords and to city life in Sigtuna harbour, which is within short distance.
