I think that rolex owns the front of the boat (and marks). US sailing owns the back of the boat the Yacht club owns the middle of the boat The sailor owns the sail.
No sunglass sponsors... Hobie gave a piece... ... Nothing that competes with Gil in the equip and shirt Business....((they give shirts to competitors)
Advertising is controlled by ISAF Regulation 20, the pertinent sections of which are 20.3, 20.4 and 20.7:

20.3 Competitors & Boats 20.3.1 Subject to any other provision of this Code: 20.3.1.1 each individual Competitor may, with the agreement of the Person in Charge, display Advertising on clothing and personal equipment without restriction; 20.3.1.2 Advertising chosen by the Person in Charge may be displayed on hulls, spars and sails without restriction except on the spaces reserved for identification by Appendix G of the Racing Rules and under Regulations 20.5 & 20.9.
20.4 Event Advertising 20.4.1 Subject to Regulations 20.5 and 20.6, the Organizing Authority of an event has the right to make use of the following spaces according to the following terms: 20.4.1.1 Boats (a) the first 20% (or where the Hull Length is less than 8 metres the greater of the first 1.2m or 25%) of the forward part of each side of the hull of each participating boat for Bow Numbers and the Advertising chosen and required to be displayed by the Organizing Authority of that event; and (b) subject to Regulation 20.9.(b).(i), the foremost 20% of the mainsail boom; and (c) if the boat has a backstay a sponsor’s burgee or flag measuring a maximum of 500mm by 750 mm (“Sponsors Flag”) to be attached to the backstay; or any combination thereof and if any such Advertising as specified to be displayed or carried (as appropriate) as above mentioned, it shall be so stated in the notice of race, which may also require that a Sponsors Flag be carried throughout that event, including when a boat is in harbour or ashore.
A Competitor may choose not to display any Advertising which is for alcohol or tobacco, or which he or she genuinely objects to for substantive moral, political or religious reasons.

20.7 Conflicts between Competitor and Event Advertising 20.7.1 The Organizing Authority of an event may not reject or cancel the entry of a boat or exclude a Competitor because that boat’s or Competitor’s Advertising is or may be in conflict with the Advertising or sponsor of that event.
Only when boats are provided does the OA "own the whole boat".
Also - be clear - Hobie Polarized (the sunglass people) contributed $, not Hobie Cat Co. They are two, very different companies that just happen to license the same trademark.
