Bob,
If it is of any help, we have got a 5000 US$ Taipan 4.9/F16 on offer here in Florida.
It has got a new F16 jib and mainsail, so it doesn't have the jib blocks on the trampoline anymore giving this boat ample tramp space.
It comes with spare sails, I believe, as in the older Taipan 4.9 suit of sails. This boat was raced to a win by Michael Coffman in the round the Island race some 3 years ago, so it is a good boat.
This may just be the boat for these youngster as it doesn't involve a too high investment moneywise; while still giving them a pretty decent racing boat.
This boat has a add in the catsailor webpage classifieds.
