RS200

There is a decent fleet of tasar and 200s at HISC, but not much crossover, whereas quite a few of the tasar sailor are or were recently in merlins. So the weight difference between the two is significant enough for the average sailor at club level and enough difference for the two to cohabit the same club happily. 

Generally my point is, if you're 115-135 kilo, then a 200 is probably as fast as you will go whilst staying competitive) without sticking a trapeze on. 

I do sympathize with the evaluation of the 200 not really hitting it's PY inland, and it's actually still quite difficult in most places unless you have broad reaches. The spinnaker makes for interesting racing, but if you judge it by laps times only then it's a very questionable addition. At the endeavour Stu Bithell did away with it and straight lined the shore doing quite nicely, the laser boys gained a few boat doing the same. 

However, I am not sure the tasar is an obvious solution to the 200s deficiencies. It really sticks below 7 knots and a 200 will beat it on most points of sail except dead downwind. The 200 kite can be frustrating in fluky light conditions and constricted waters, the the Tasars tacking mast and sliding shrouds, plus the mainsheet / traveller set up can make the repetitive tacks and gybes quite the task. 

The Ent really is a great boat in that regard, simple and effective. However, the class really seems to have dropped away (except in looe!). The 12 is also great, but has an ideal weight below that of the 200. 

All in all the 200 is fairly quick, certainly in terms of average speed if not time around a course! It's quite robust and not as heavy as similar more 'training' orientated configurations. There are a few niggles to watch out for which I went through in my first reply.
