OMB Approval No. 1024-0018 NPS Form 1 10-900-a 8-86) United States Department of the Interior National Park Service National Register of Historic Places Continuation Sheet Coast Guard Motor Lifeboat CG 36500 Orleans (Barnstable), MA Section number_] Page1 Section 7 Description The motor lifeboat CG 36500 was built in 1946 at the Curtis Bay Maryland Coast Guard Yard, the production facility for all 36-foot TRS model boats. The TRS model 36-footer was the standard-issue lifesaving boat for most US Coast Guard Life Boat stations for many years.
The CG 36500 was stationed at the Chatham, Massachusetts, Coast Guard Life Boat station in 1946 where it remained in service until 1968. Most 36-foot TRS model boats have been destroyed. Some 36-foot boats have been restored for museum exhibits; however, few have been restored to their original seaworthy condition as designed and constructed. Now more than 50 years old, the CG 36500 is a floating museum capable of the original rescue function for which it was designed. The CG 36500 is a heavily built double-ended, self-righting and self-bailing motor lifeboat designed to withstand the most severe sea conditions that its crew could tolerate. This particular boat has proven to meet her design criteria.
It is designed to roll over and recover upright by means of features including a ballast keel and skeg made from solid bronze weighing 2,000 pounds, watertight compartments, and scuppers above the splash rail to drain water. The overall length of the boat is 36' 8" with a 10'2 3¾'" bean and 3' 5" draft. The boat weighs 19,600 pounds. The CG 36500 is currently capable of a speed of 8 kts. and a cruising range of 200 miles. (photo # 5) Detailed Vessel Description and Construction Materials The boat's keel is fastened with silicon bronze bolts measuring 8" x ½" diameter. The hull is enclosed with 1/16" Monel ice sheathing fastened with 1" #12 Monel wood screws. The stem and sternpost guards are made of cast bronze. The quarter guards are 1" solid half-oval bronze over seven quarter 4" × 24' white oak, fastened with 3/" silicon bronze carriage bolts.
The rub rails are two laminated layers of six quarter white oak trimmed out to measure 3" x 6" x 39'. They are fastened to the hull with 3/8" silicon bronze carriage bolts and #14 3" silicon bronze wood screws. (photo #8) The boat's backbone, deadwood and steam-bent frames are made from white oak. The planking is 1 1/8" cypress above and below the waterline. The sheer strake is 1 3/8" white oak. Planks are fastened with #12 and #14 x 2 ½" silicon bronze wood screws.

The covering boards are four quarter x 6" x 38' white oak, fastened to the deck frames with #14 x 2" silicon bronze wood screws. The toe rails are ten quarter x 4" x 18' white oak. The hand rails are five quarter x 2 ¼" x 6' white oak fastened on 10" centers with silicon bronze lag screws. (photo # 1) The forward cabin is made of two layers of ½" pine or cedar laid over 1½" square steam-bent white oak frames. The main deck forward is 5/8" white oak laid over ¾" marine plywood. The deck is bolted to the fir framing below. The stepped-down margins include five quarter white oak leading to the scuppers. A bronze circular access hatch is located aft of center allowing access to the amidships bilge pump. The bilge pump float switch is mounted fore and aft to the oak keelson. The existing fuel tank is manufactured from fiberglass, secured with fabricated bronze tank straps.
The original fuel tank was made from galvanized steel. The diesel fuel tank has a 1 ½" bronze fuel fill with an appropriate pipe cap. The exact fuel storage capacity is not known, but it is in excess of 220 gallons. (Underway, the GM 4-71 diesel engine consumes about five gallons/hour at 1,700 rpm.) The fuel line leads to a Racor filter mounted on the port side of the engine room bulkhead. The wheel deck, or coxswains flat, is built from fir planks with margins of five quarter white oak. There is circular bronze access hatch on the starboard side allowing access to the compartment under the wheel deck. This can be flooded with seawater for use in the winter as a slush free cooling reservoir. Two gate valves are mounted on the aft engine room bulkhead that are not connected to any cooling water hoses, but could be employed if needed.
There is a very useful grating made from teak that elevates the coxswains' feet above sea water sloshing back and forth between the scuppers. The steering wheel is not original, but an exact replica made using USCG drawings. The engine throttle are gear are regulated with a Morse control allowing one hand speed and (continued) PS Form 1 10-900-2 United States Department of the Interior National Park Service National Register of Historic Places Continuation Sheet OMB Approval No. 1024-0018 Coast Guard Motor Lifeboat CG 36500 Orleans (Barnstable), MA Section number 7 Page3 direction control. Navigation aids were traditionally limited to a compass mounted to the bridge deck where a Ritchie compass is now located. Additional navaids now consist of a Garmin 176c GPS unit that replaced an earlier Loran and an Uniden MC 795 VHF radio with extension speaker to meet current safety standards.
(photo # 7) The aft watertight compartment is covered with two layers of ½" pine or cedar, attached to 1 ¾" square steam-bent frames, gown white oak knees, and white oak blocking. There are two removable wooden gratings above the steering gear located below. The emergency steering arm is stored in this compartment. A bilge pump is not located in this area since water cannot collect here due to the rise in the keelson at this point. The engine room compartment, located amidships, is covered with two layers of 1½ oz. mat with polyester resin applied over cedar or pine laminated covering. The structure is supported by 1 ¾" square steam-bent white oak frames. A copper cowling is attached to the aft part of the compartment above the bridge deck that attaches to a mahogany and glass windshield. The windshield and compartment provide some protection to the helmsman and crew.
A canvas dodger attaches with snaps to the perimeter of the area. The collapsible dodger has not been employed on the boat, since it restricts vision and is not needed in the summer. The engine is supported by engine beds of 3 ¼"x 6 ¾" white oak resting on 2 ¼"x 6 3/4" fire engine stringers, fastened with 3/8" silicon bronze carriage bolts and notched- over floor timbers. The port and starboard battery and equipment shelves are 3%" plywood with white oak fiddles. The shaft log is 5" x 6" white oak with a 2 ¼" ID lead pipe insert. A 90-horsepower Sterling Petrel 6-cylinder gasoline engine originally powered the CG 36500. That engine was replaced with a General Motors 4-71 diesel, model 471RA48A, serial number 4A-1420 developed by Detroit Diesel in the 1950s. It is believed that the new 4-cylinder engine was installed at Woods Hole, MA in 1956. The 4-71 was removed and overhauled in 1998.
A new/rebuilt starter was installed in September of 2003. An Allison transmission containing a forward and reverse gear is shifted by means of a (continued) NPS Form 1 10-900-2 (8-86) United States Department of the Interior National Park Service OMB Approval No. 1024-0018 National Register of Historic Places Continuation Sheet Coast Guard Motor Lifeboat CG 36500 Orleans (Barnstable), MA Section number 7 Page_ 4 Morse control on the bridge. Two heavy-duty batteries are located port and starboard in the engine compartment, encased in vented battery boxes. A float-activated bilge pump is located under the engine on the starboard side. Two opening ports forward and a solar-powered vent fan in the overhead ventilates the engine compartment. (photos #2,6) Beneath the waterline, cast-bronze rudder halves direct the boat's steering.
Propulsion is transferred through a 1 ½" monel standard morse tape shaft supported by a cast bronze stern bearing. The shaft exits the hull through a rubber-sleeved cutlass bearing, then attaches to a 3-blade 26 x 21 R/H bronze propeller. The cutlass bearing was replaced and a reconditioned prop was installed during the 2003 haul out. It is estimated that 80-90% of the boat's original fabric survives intact. This survival rate exceeds most wooden hull vessels listed in the National Register, which range from 5-95% of the vessels' original fabric. (photo # 3) The Coast Guard Motor Life Boat CG 36500 retired from active service at Station Chatham in 1968. At that time the Coast Guard transferred the boat to the National Park Service at the Cape Cod National Seashore to be displayed in a maritime museum that was the be developed by the Park Service.
In 1981, after not having been maintained for 13 years,the boat was transferred to the Orleans Historical Society, which currently owns and maintains it as a floating museum dedicated to the Lifesavers of Cape Cod. Extensive restoration was undertaken in 1981 with private funds. A survey conducted in November and December of 1997 at the Pease Boat Works in Chatham revealed the need for additional overhaul of the hull and engine. That work was completed through a combination of private donations and a 1999 National Heritage Maritime Grant (#25-97-MH-07012). All restoration work was done in accordance with the Secretary of the Interior's Standards for the Rehabilitation of Historic Vessels. The CG 36500 meets or exceeds the standards it possessed when it was in active service. The boat is currently displayed by the Orleans Historical Society, Inc.
and a volunteer crew in the winter at Rock Harbor in Orleans from May until October. The boat winters (continued) Coast Guard Motor Lifeboat CG 36500 Name of Property 8. Statement of Significance
