After I start something is seems that I get addicted. Happens all the time, so why am I not surprised that within days of launching my first model boat, I already own another one. I purchased the Miss Madison, for a good price because it was missing a few bits and now am gathering all the necessary parts to get her going. RC Universe Forum is proving to be a great resource for learning.
Life is not to be measured in the number of breaths we take, but in the number of moments we make.

A Full Weekend
Friday: We launched Baby Doll on the Pond at Ratline Shipyards. Official guests included Flight Captain Laurie, Master Shipwright Clive (Ratty) Gilbert, the good Lady Sponsor Eddie, Gaye and me. With the Flight Captains urging I got a bit excited during the first run and flipped the boat. I tried to claim a rogue wave, then wardrobe malfunction but it was plain to all, it was operator error. After the flip, all the Flight Captain and I could do was fall over in the mud laughing. Not so for the Shipwright. Having been intimately involved in the build of Baby Doll, all he could see was 100's of dollars of electronics getting drowned and took off at a sprint across the pond to retrieve the still revving, upside down boat. The flight Captain regained his composure shortly before me and luckily before the Shipwright retrieved the boat and reminded me to de-throttle the engine. It is well I did otherwise we might have had to add lacerations to the injury the Shipwright sustained during his retrieval dash - namely a corked thigh muscle and a pulled Achilles.
After a quick inspection for water damage, we set Baby Doll back on the lake for further sea trials. I must say she looked a beauty and finely balanced when sitting up on her planing surfaces at 10 knots. All went well until she determined to investigate more closely dry land on the other side of the lake and promptly settled there for a little rest. It was obvious that she was not going to find the water again with out assistance, as it was also obvious that a little walk would do the Shipwrights injuries the world of good. So as the assembled guests settled into afternoon tea of fresh baked sticky date scones and tea, the Shipwright made his way around the lake on his injury healing journey to set baby Doll free of her muddy shackles.
The rest of the day was thankfully incident and injury free.
Saturday: The stars, the moon, the sun and the planets, along with the wind and water conditions all aligned for me today and I got three PB's out on the lake windsurfing.
Top Speed 36.5 k; 5 x 10sec Average: 33.5k; Nautical Mile: 27.5l

A couple of days before Red and Jacques also had a great sail at Conawarree Lake scoring a bunch of PB's. Here are their results at GPS Tema Challenge site. http://gpsteamchallenge.com.au/sailor_session/show?date=2010-01-02&team=29
Sunday: Surf in the morning followed up by and abusive conversation with a fellow motorist who had parked her car in the middle of the road to make a phone call to her Mom. It appears momsie was involved in a car accident and needed to urgently talk to her daughter about it. I suggested that the likely cause of the accident was that momsie was likely on the phone at the time. In the afternoon I attempted to do 100klms on the windsurfer but fell way short. Anyway a hearty chuckle at someone elses expense always makes for a good day.
Monday: A promising weather forecast had Red and me up early for the 4 hour drive to Sandy Point for more windsurfing. It was magic sailing, but the wind was too far south for any descent speeds.

Baby Doll Update
Baby Doll has a permanent home. She now resides on the shelf in the lounge room. After delivery from The Builder there remained several small jobs to complete; mainly the set up of the remote control; connect the power source; charge the batteries; and finalise the water cooling; install drive shafe gland seal.
Some guidance from the Flight Captain set me on the right path for safely handling the LiPo battery and channel selection so that the throttle and rudder controls could work. Still dealing with the problem of the propeller running backwards. The instructions say to merely swap any two of the three wires between the motor and the ESP, but I'm not confident in doing this until I can get additional confirmation that this won't short the battery out.

Lithium Polymer batteries require a great deal more care and attention that their older cousins, NiCad and Nickle Metal Hydride. The main concern is to not allow them to discharge any more than 20% of their max charge. To do so will permanently damage the battery. The ESC manages the 'low voltage cutoff threashold' and detects the the battery's voltage at any time and if the voltage is lower than the threashold for 2 seconds, the output power will be reduced by 50%. Recharging before further use is mandatory for continued safe battery operation.

New Owner Takes Delivery of Baby Doll
Last week at Ratline Industries Boat Yard, the new owner took formal delivery of the Italian Speedboat 'Baby Doll'.
Several essential formalities were observed. These included;
An extensive training and familiarisation course conducted by non other than the master shipwright himself, Capt. Ratty Gilbert. The new owner was reported later to say that whilst he had hoped that the famous Capt Ratty would attend the ceremony and festivities, he did not in his wildest dreams think that he would actually meet and shake the hand of the famous and ageless craftsman and founder of the prestigious Ratline Industries.
Once the formal signing of the ships papers were completed, all gathered for the ceremony toasted to the ship and the builder with a sip of the finest Limited Edition Ardbeg Blasda Islay Single Malt Scotch Whiskey.

Baby Doll Takes Shape
After exploring options for running gear for Baby Doll whilst in Sydney, Ratty and I had a coffee meeting to discuss the best way ahead. But first the photos. Ratty brought Baby Doll over for the obligatory construction inspection. She passed with flying colours. Here are the pics...
Just love the detail - right down to hand made steering wheel and the gauges. I forgot to check the speed and RPM. Must do so at next inspection.
The parts decision needs to take into account aesthetics and cost and boils down to two options.
1. Buy a completed off the shelf boat and strip out the parts we need. The benefit here is that all the parts will be matched, like motor, propeller, radio frequencies etc. And I can get a Joysway Red Off-Shore Warrior for $319.95. It has a B2445 (30 AMPS) water cooled motor and ESC. This is cheaper than the combined parts purchased separately. but aesthetically not too good, as all the running gear is hanging off the back of the boat.
2. Buy the parts we need separately. With begged, and borrowed parts, mainly from Laurie, this will definitely work out to be the most rewarding option. Down side is matching the bits correctly.
We decided that the most important thing to do right now to keep construction going was to buy the motor and propeller shaft assembly. I can get this from the Northern Beaches Hobby Center.

"Baby Doll" - The Italian Speed Boat Project


At an Extra Ordinary General Meeting held today, Master Boat Builder Sir Ratty Gilbert from Ratline Boat Builders Ltd presented to the committee the plans for "Baby Doll" the Italian Speedboat along with a half model which he used to experiment with different build methods and options for build materials.
After Sir Gilbert's presentation and close inspection of the build methods by the committee a vote was taken to proceed to Stage 2 of the build process. It was agreed unanimously that the resourceful craftsmanship displayed fully 'rat'ified the committees decision to use Ratline for this rare project.
