Grega,
I think that boat is a Sea Spray. It originally had a trampoline and did not have a dolphin striker. So unless you are putting a larger mast and sail area on it than came with the boat originally, you would not need to add a dolphin striker.

It appears that someone probably put that wooden platform on it when they added that outboard bracket and turned it into a motorboat.

There are some pictures of the Sea Spray at http://www.thebeachcats.com/modules...mp;file=index&include=view_album.php

Where do you sail? There are still quite a few Sea Sprays in the northwestern United States and Canada.

Of course, I could be wrong, and maybe it is not a Sea Spray at all, but it sure looks like one.
