We own a Standfast Loper, and I can tell you that it handles great. It can take a lot of wind before you have to reduce sails.
We have just started a new website on standfast lopers, the site is still under construction but already contains some info (much more will follow soon). You can find it at
If you buy the Standfast Loper, then please send us a piture of it and the serial number and the marina where it's located and we will put it up on the website.
Hope this helps you
