TYEE is a great coastal cruising vessel that the current owners have cared for and updated since taking delivery in 2004. It is unique with having the flybridge on top of the pilothouse, which not only gives the helmsperson better visibility from the helm, but also creates a spacious aft bridge deck. This is a yacht worth your time to tour.  

Items that will need some attention:

  • The foredeck non-skid needs to be painted. 
  • All of the varnish was refinished in 2023 with the exception of the foredeck cap rail. It is in good condition but did not receive a fresh coat of varnish.  
  • The flybridge helm does not have a helm cover. It should have a helm console cover.
