Sirens are like the VW van of microcruisers. Not quite as well equipped as a VW Westfalia camper, but able to do the job with some creative packing and packaging. The Siren is pump-out sanitation capable, has an optional boom tent, and IMO has protected more greenhorn sailors sailing at 11/10ths of their abilities than any other 17' boat.
They are good value. $1500 will buy a usable boat on a trailer. $3500 will buy you an exceptional boat on a trailer. You can usually sell your Siren for 100% of the purchase price 2-3 years later- try that with any other cruiser.
I guess I will keep an eye out. Thanks for the info.
