1837 A light-boat has been built and stationed off Upper Cedar point, in the Potomac, according to the decision of the Navy Board in reference to the appropriation for a light-boat or light-house in the Potomac river, between Matthias point, in Virginia, and Maryland point, in the State of Maryland.
1838 Upper-Cedar-point light-boat.Captain and crew absent. At half past eight P. M., the mate called on board the cutter, from whom I obtained the following information: The boat requires calking, painting, and some other slight repairs; the lantern is hidden by the head of the slides; it cannot be seen three hundred yards when the boat is head on.
1845 Upper Cedar Point (light-vessl), off said Point, below the Narrows, and about 44 miles below Mount Vernon. One lamp with 6 cylindrical wicks, 34 feet elevation from deck. Built (first) in 1821. New vessel built in 1839, tonnage 72.
1855 Upper Cedar Point, Potomac river.This light-vessel was thoroughly repaired last spring, and was fitted with a new illuminating apparatus, consisting of a lantern containing 16 panes of large sized plate-glass, and a new Costan lamp, in place of the old style lantern of 48 panes of small sized common glass and the old style common bowl-lamp. The Costan lamp was first exhibited on the 17th May, 1855.
1859 The light-vessel removed from the Ocracoke inlet, in North Carolina, under the operation of the 3d section of the act of Congress approved March 3, 1859, is being repaired and refitted for use as a relief vessel for the waters of Pamlico sound, and the vessel removed from the Nine-feet shoal, in the same waters, under the operation of the same act, has been transferred to the Potomac river to take the place of the Upper Cedar Point light-vessel nearly worn out.
1860 - Ninefoot shoal light-vessel has been fitted out, and sent to occupy the station of the Upper Cedar Point light-vessel, on the Potomac river, this latter vessel having been found to require extensive repairs.
1861 Between the 19th and 24th April, 1861, the two light-vessels in the Potomac were wantonly burned, and four in the Chesapeake between the mouth of the Potomac and Hampton Roads were removed and their apparatus carried off or destroyed. Two of these light-vessels were subsequently recaptured, but they had been stripped of everything that could be removed.
1864 Two of the light-vessels which were mentioned in the last annual report as being detained in New Bedford, under the lien law of the State, for debts due by the contractor, have been placed upon the stations on Upper and Lower Cedar Points in the Potomac river, for which they were originally designed. A competent guard for their protection has been detailed from the army.
1867 Before the war, the aids to navigation in this district included a great number of light-vessels, many of which were in waters not subject to heavy seas, and but rarely to ice of such mass and strength as to make it dangerous to permanent structures. The rebellion had swept away all the light-vessels in the sounds of North Carolina, and some of those in the lower Chesapeake. In reestablishing these stations the opportunity was presented to carry into effect an object long had in view by the Board, viz., to replace the light-vessels, wherever practicable, by permanent structures, because of their greater economy, both in construction and maintenance. Generally the stations occupied by light-vessels are of such a character that the screw-pile light-house is the most eligible form of construction for any permanent substitute. This is particularly the case in the district in question, owing to the slight elevation of the adjacent shores and their swampy formation, the shallow water and the nature of the bottom. Since the last annual report screw-pile light-houses have been erected upon the eight following stations, formerly occupied by light-vessels, viz: Roanoke river, Harbor island, Southwest Point Royal shoal and Long shoal, in North Carolina, Upper Cedar Point, Hooper's straits, and Janes' island, in Maryland, and Lower Cedar Point, in Virginia, at a total cost of one hundred and twenty-one thousand and one dollars, ($121,001,) which, under the authority of the second section of the act making appropriations for light-houses, light-boats, buoys, &c, and providing for the erection and establishment of the same, and for other purposes, approved March 3d, 1859, has been charged to the appropriation for seamen's wages, repairs, &c, of light-vessels. Thus far, no light-vessel removed or destroyed by the rebels has been replaced by a new one built for the purpose.
1867 Upper Cedar PointUpon the completion of the new screw pile light-house intended as a substitute for this vessel, it was lighted for the first time on the night of July 20, 1867, and the vessel taken to Norfolk, put on the ways, her sheathing thoroughly repaired, and painted red. On the 17th August she was taken in tow by the tender Heliotrope and placed upon the Willoughby Spit station, the iron vessel formerly occupying it being no longer fit for service. The vessel now marking Willoughby Spit is in excellent condition in every particular.
