this may seem weird but we just bought a used helson 22 from the ORIGINAL maker of the sea pearls--Marine Concepts. Jim it the owner/operator and he just got into brokerage boats so i bet anything he would take your venture in on a trade for a sea pearl. here is the info--
243 Anclote Road
Tarpon Springs, Fl
800-881-1525 or local 727-937-0166
they have several sea pearls for sale. GOOD LUCK AND THEY ARE GREAT GUYS TO DEAL WITH!!!
LET US KNOW HOW IT GOES!
