An aircraft carrier! Thursday 17 August 2006 Telephone : Fax : Enquiry : Sea-Me. we have one on order from yacht-bits who offer a ss bracket to go. Problem is there is zero space at mast head. We are a catamaran with 67\' mast. Would bracket attachment forward of the mast seriously impact performance? ian h How did you hear about Sea-me : I saw the signal from one at sea! Thought it was an aircraft carrier.
