Beginner sail boats.
There is a discussion here
http://www.modelboatmayhem.co.uk/forum/index.php?topic=13426.0First thing to consider, what are others sailing at your club? And other clubs in your area.
If you get something the same, or in the same class, you will be able to race with them. You may not consider racing now, but it can be a bit of fun to add to your sailing day. Or for others it can also be competitive.
If you are interested in a particular boat post on here again asking abut the different user/racing groups for particular boats. visiting their websites will tell you what clubs in your area race that boat. For example I know there is an active grpup for MicroMagic and footys.
Next question, how big do you want?
If you want it small enough to fit in the car rigged, then look for boats of about 2ft (600mm) length. These are about 3ft-4ft (900-1200) tall with the keel bulb. They will lie down fully rigged in the footwell of the back of most European (compact) cars.
Boats to considerKyosho Seawind or Kyosho Seadolphin
Thunder Tiger Victoria

http://www.modelboatmayhem.co.uk/forum/index.php?topic=4231.0easy to build, sails straight out of the box and is often upgraded for racing.
I have one and love it, it was my first boat.
Graupner Micro Magic, a RTR model that is seen as a bit pricey, but is becoming very popular across EU and UK.
Graupner Saphir/Venus
Robbe Comtesse. Beautiful model sails well.
Nirvana II, RTR that has some good reports.
Laser - Goes together in seconds, a bit fidly to learn to sail, but then very fast. Easy to transport in thier own bag. Downside is they are not cheap.
If you want something different Look at Victor models
www.victor-models.com . These kits require more building.

Mary J Ward - a fishing schooner (my avatar is a picture of a modified model) build log here
http://www.modelboatmayhem.co.uk/forum/index.php?topic=2716.0Fairly easy to build.
Ruby B - a sailing cutter, looks like it is built on the same hull as the MJW
Consider scratch buildingRG65 - build log
http://www.modelboatmayhem.co.uk/forum/index.php?topic=4027.0 Footy - these boats are only about 1 foot long (300mm) and are a new class. They are a fun boat, but because they are small they tend to bob about on the water. They are very popular.

http://www.modelboatmayhem.co.uk/forum/index.php?topic=6141.0There are also footy pirate boats, brigs, etc.
I would not recommendAny other RTR/ARTR under 2 foot (600mm), the only ones I know are more toy grade than hobby grade.
Seemingly cheap RTR Chinese boats. They come with a radio that may need to be replaced (the heart of any value), and the build quality (especially sails and rigging) means they need a lot of work. This defeats any perceived value and even their readiness for the water.
