Another damaged fiberglass hull rescued. every thing else made by me. At 3/4"=1' a very big model. Completed 2012 but only sailed twice, a very good sailor just needs a big lake. The mast lifts & folds forward after removing the hatch. The top mast lowered, the bowsprit retracted and the sails raped around the shrouds, held in place with masking tape. ( this stops the lines from tangling.) Takes about 5 minutes to reassemble.
This model was scratch built from US Coast Guard plans. The boat is constructed of balsa wood and the hull coated with fiberglass resin. All the deck gear is scratchbuilt from brass, the propellers, led's and figures are the only commercial parts. Scaled at 3/4=1 foot the model measures 42 inches in length.
It's powered by a Pittman 12 volt motor and controlled by a 4 channel radio. Working features are running and spot light, siren with flashing blue light, sweeping radar antenna and deck lights. Built in 1985 the model the lifeboat is accurate in appearence for that time period.(The prototype has been modified since).
The actual lifeboat is attached the the Coast Guard's Motor Lifeboat School at Cape Disappointment and is one of four boats of this class.
This is a 40" long model of a gas powered Berkley Company kit of a US Air Force crash boat from 1955. The plank on frame kit was in production for about 10 years and was meant to be powered by a model airplane gas motor with a single shaft. it depicts an experimental 50 knot rescue boat (painted in a peace time color scheme) during service with the USAF. if successfull it would have been put into production designed to be a replacement rescue craft for all Air Force 65' crash boats. Unfortunately for the crash boat program the Air Force lost interest as helicopters were become a reliable way of rescueing downed pilots along the coast. The prototype and a sister boat were scrapped, as was the entire program.
The model was given to me to be restored(top picture) for the son of a retired USAF veteran that was a crash boat crewman. The model was built in 1957 and had been run a few times on a tether line, R/C was pretty expensive back in the day. I stripped the hull, filled in all the cracks and rebuilt the mast. I added a small boat, davit, liferaft, coxswain station, spray shield and deck hardware among other things. Actually all the owner wanted was a paint job, he was very happy with it's new appearencep! Although I fiberglassed the wooden hull and made it watertight, the owner doesn't plan to run it, just a memorial to his dad's service. I really enjoyed working on this "rare bird".
Based on the US Coast Guard 36' motor lifeboat, the Canadian Coast Guard operated a number of these boats modified for cold weather operation. The model is a fiberglass hull, the reat is scratchbuilt using baltic birch wood, brass, and plastic. The model measures 28" based on the scale 3/4 inch equals a foot. it's powered by a 6 volt Dumas motor and operated with a 2 channel radio. A fun build!
I've just been given this fiberglass hull and am wondering if anybody can recognise what it might be please .
It's 71cm overall with a beam of 23cm.
Any information appreciated

Not your typical submarine but certainly an unusual semI submersible. Scratch built by fellow club member Brian Clewes this is a most striking looking vessel. Fiberglass hull and moulded perspex window. Home built waterjet uses a large 900 (I think) brushed motor, water cooled speed controller and 14.4v LiPo. Looks really spectacular on the water and Brian is working on the ballast to enable the model to remain just submerged. Video to follow in due course.
this hydroplane had to have major work done to strengthen both sponsons internaly as well as filling with expanding foam,this stops it from sinking in the event of a flip over and to put a little weight in the front to help keep the nose down.
fitted a tuned wrap to center pipe,water pump and also added extra fiberglass on the bottom because this was so thin it was flexing at speed and was hitting the bottom of the engine!!!!!. re-painted it too and put my own choice of graphics on.
I fitted the pulse water pump because I wouldn't be running flat out all the time and needed to cool the engine at lower rpm's,and the pulse water pump would do just that with twin inlets and outlets to keep the exhaust and engine head cool.
hI alan,
a pulse pump works off the pressure of the downward stroke of the piston, as the piston moves down pressure builds up in the crankcase bottom and with a small tygon fuel line fitted to the insulator block that the carb sits on you can tap into the 'pulse' of pressure that's created and its this that works a diaphragm inside the pump, it pumps water when your boat is not traveling fast enough to cool itself through the water intakes.
at the start of my interest in boats I thought of fire boats, RNLI type of sailing but the detial on some of the tugs are amazing!! giving it some thought at the moment what to get into 😎
This model was built from scratch except for the fiberglass hull, using styrene. The drives are Graupner VSD's and the 10 fire monitors are powered by BMW windshield washer pumps. The radio is a Spektrum DH 6 with a twin stick modification and fitted with a switch 8 to individually operate the monitors.
BRAVO ZULU! Again, very nice. The multifunction of your boat is great and lends alot of ideas. I'm definitely gonna look into the Windy City fireboat.
I once saw her up close when on vacation in Chicago in 97.
