Hi Phil,
Based on the members here (I've been managing the site (and approving every member) for 13 years) there are certainly pockets of Aquasports - Florida (for sure - both coasts), the Delmarva (Delaware, Maryland, Virginia) and the Northeast - the biggest concentration is all the way up the east coast.
We have a few members in the west (maybe 50) in Cally and north to Oregon - their boats are chosen for the deep water of the Pacific, usually a more robust Family Fisherman and Express Fisherman line due to the high gunwales and big dance floors in the aft. They are great contributors on how they customize and rebuild their boats to accomplish the needs of the Pacific.
We have a sporadic membership around lake areas like the Great lakes, Nevada and other areas. We have a lot of members from the deep south along the Gulf of Mexico (Texas to FL) too.
The big surprise is that we have a ton of international members - maybe 100 - ranging from Australia, New Zealand, Guam, Singapore, Spain, Italy (we have a lot of members from there), we have several members from Greece, Crete. We also have members from the "north", Canada, Sweden, Finland, Down south we have members from the Caribbean - Cuba, Puerto Rico, Aruba, Curacoa - I'm sure I'm missing a lot - its amazing where these these boats are found and how they got there. I just approved a new member from Italy today. We are a HUGE family!!!
We can help you find boats and hopefully our membership can physically look at the boat for you. Life is busy for everyone, so be patient.
