Dinghies with keels

The K1 is a lot narrower and lighter than a Stratos Keel (1.22m/2m and 105kg/290kg) so is going to be a radically different sailing experience. The K2 has an all up sailing weight if 155kg so it is probably half the all up weight of a Stratos Keel, it's also a fair bit narrower at 1.62m. They are much more performance orientated than the SK

Thanks for all the suggestions, guys; they've given me some good pointers to think about. Somebody also suggested a K6 - another for me to investigate.

A long rope and a car helps with a FF.  Alternatively you could buddy up with the other one. Four people should have no problem launching and recovering a FF if the slipway is not stupidly long and steep.  That's what we used to do in Penzance without a winch.  They are lovely boats by the way but way heavier than a K1.

We have at my club: K1, flying 15, tempest, k6 and sailability have a Venture with forward facing seats. The K1 is really a single hander though I know one pair who sail one together. K6 is a bit of a handful due to the huge kite, won't capsize but will broach and we've had a couple of expensive carbon mast breakages. Flying 15 looks like a lovely boat,but the tempest sailers say it's a dog ..I think they mean that it rewards vigorous hiking ( tho the FF owners at my club NEVER hike) Tempest needs a 15stone crew on a trapeze or that will broach merrily. Tempest and FF need s very deep slipway due the fixed keels. I reckon the K1 is a good boat for the single older sailor, maybe the venture for two up cruising.
