Winter in Lagos
Sarah and I spent the winter of 2006/2007 in the very pleasant port of Lagos, PT berthed in the very hospitable Marina de Lagos.  My experience that winter allows me to recommend this port and marina without reservations for anyone wanting to spend a winter in a mild climate in good company.  The town of Lagos offers a number of very good and affordable restaurants, and active agenda of social and cultural events.  The marina management go out of their way to provide a very accommodating facility and offer monthly activities for berth holders during the nine months of the fall, winter and spring.  These activities included chartering the Boa Esperanca Carvel replica for the berth holders, gifts at a pre-Christmas dinner, a tasting of Portuguese wines, and other activities.  There is also an active cruiser club in the Marina which organizes a VHF net, monthly session on particular aspects of cruising and sailing, and frequent social (Robert Burns night, whiskey tasting, quiz nights, bridge clubs, etc.) and educational (Portuguese language) sessions.  On the other hand if your preference is to become a hermit on your boat for the winter, Lagos is probably not the place for you.

Many of these activities are organized by the Lagos Navigators cruisers club.
The cruiser community in Lagos is very multi-national, but predominantly British.  Most of the pubs and restaurants in the Marina cater to the tastes of the Brits.  Consequently I have become addicted to the Full English Breakfast (the original meaning of the "Full Monty"), however I have managed to avoid becoming a fan of Cricket or European Football (aka soccer).  I did find Rugby watchable.
Ponta de Piedade

Boa Esperança
Click on picture to view at full resolutionThe Boa Esperança is a replica of a Caravel.  The Caravel was developed by the Portuguese initially as a fast and sea worthy fishing vessel, then they became the vessel type chosen for the voyages of discovery. 
Boa Esperança is docked at the Marina de Lagos and is used to take guests on an excursion along the Algarve coast.  At the end of October, 2006 the Marina arranged for berth holders to have such an excursion.

The tiller is the only mechanical advantage used to steer the Boa Esperança.  When going straight it to took a moderate amount of effort to keep the Boa Esperança on course.

Tavira
