Quote from blog :-
"The paddling action is produced with a combination of mechanics and software control. A few changes were made to the software to improve the ability to steer. There is still more to be done to improve this. If you watch carefully at 0:35 seconds in the video, you can see the rudder compensating for the paddle stroke to help keep Katie moving in a straight line."

"Katie the Kayaker" was the inspiration and result many hours of work and head scratching by designer/creator and modelmaker Graham Royle who is a member of the Buxton Model Boat Club.

Here is Gaham`s latest account of the - "Maiden Voyage"

Before the maiden (!) voyage, a quick head 'transplant' !! I'd like to introduce 'Katie the Kayaker' 😂🤣

It was with some trepidation that Katie was carefully launched onto the Buxton lake. An ideal day last weekend with very little wind. I knew she would float, but would she move, and be controllable? Well the answer is yes - sort of 🤔

Thanks to Philcaretaker for the video clip.

She managed to paddle out, turn and paddle back, which was a great start. At least she didn't need rescuing. Shame she wouldn't keep hold of the paddle!

The paddle blades are not feathered at the right angle. The starboard blade is at the wrong angle and is hitting the water causing the kayak to rock excessively from side to side.

Once back on dry land, the kayak was checked inside for water. There was just a drop but nothing to worry about, which was also a relief.

So, overall it was reasonably successful, but several teething problems to be resolved before the next outing.👍

My visit to the "Hayling Island Model Boat Club".
Greg, many thanks for the warm welcome extended by yourself and the other members at both Emsworth and at Mill Rythe last week. Nice to see such a nice selection of boats.
Take care and thanks again to the "Hayling Island Model Boat Club".

Here's a few pics of the Lumba. It is ready for fiberglass and the superstructure is here just test fit. I need suggestions on how to power it; I want it to move scale, about 20 knots and it is going to be twin screw. I have a pair of 800 motors that are great but might be too much, even though I would rather this be over-powered than under. She has very cool lines, like an airplane. Lots of curves and twists all over her. She's a big girl, ready to carry quite a few angry oil rig employees on a dark and stormy night.

Information from Nerys -

In the 1940s and 50s, many traditional Thames Sailing barges were converted into motor barges. This is a model, based on photos and my memory of the 'Nellie'. The sailing barge 'Nellie' was built by Cremers at Hollowshore, Faversham in 1901,. She traded under sail carrying about 90 tons of cargo around the Thames, Medway and Swale until about 1952 and then had the gear taken out, a Chrysler Crown petrol/paraffin motor installed and carried on trading for some years owned by R.Lapthorne & Co of Hoo on the River Medway.. She was eventually sold out of trade and is now privately owned. She has been rerigged with a reduced sailing barge rig without a topsail. My model is based on a 30" barge hull from Dave Watts Mastman.

NOTE More information from Nerys - read on ........

Hi Phil,
I'll just add a little more information to that. I was Nellie's skipper in the mid 50's for a few years. We were based at Hoo on the Medway and carried cargoes around the Medway, Swale, Thames and Colne. Regular trips were such as ballast from Fingringhoe on the Colne to Hoo, sand from Upnor on the Medway to the Ford works at Dagenham, fertilizers from London to Faversham and Queenborough, wheat from London docks to Whitstable and more or less anything that could be carried between ships in the London docks to anywhere in the Estuary. We were paid by the freight. Half the value of the carriage charges going to the owners and the other half to the crew, shared 2/3 for the skipper, 1/3 for the mate, Then fuel and other expenses were divided up similarly.
Nellie, of all the barges I served on was the one I liked best. She was the smallest, but there was just something about her. However as a footnote, in the 1970's I built a forty three foot schooner rigged barge yacht in the same yard as Nellie was built.

Hello again, here’s a picture of an M class destroyer which I built some years ago, she is of again balsa construction from Model Boat Magazine plans, I built over one winter about 9 years ago, she is sealed with dope and tissue which gives a smooth finish, the guns were constructed from plastic card, with brass rods for the barrels!
She was retired a couple of years ago, but recently she was brought out retirement and gifted to family friend was showing an interest in battle ships!

Here is pitcure of both my boats sailing on a boating lake not far from my home, the larger of the two was commandeered by my 8 year old son for a trainning mission he had in mind, which gave me an excuse to build another one, which is the smaller boat the picture, as the young captain needed escorting while getting use to his new command!
They are both made from balsa wood, which the material for the hull, it is sealed with a acrylic varnish,painted over the top with enammel paint with clear varnish on top of the paint! The superstructure on the larger destoyer is made from thin plywood, and on the smaller frigate its made of plasticard!
I got the lynx helicoptors on Ebay from "The Dorest Print Man" I think it was, which are 3D printed by him!

Great video of a 90E Swedish combat boat. Water jet powered.

52ft
2x 625 HP Scania DS114 V8
2x Kamewa water jets for 40knts

Impressive,- I want one😁 (you can pick one up for NZ $ 157k at the moment, -one careful lady owner (and a hundred rough Swedish army buggers) Make a good jet model.

Once again our intrepid members meet at Josey Ranch in Carrollton Texas to have fun, give each other a hard time and promote the hobby of model boating. 😀

Following the "Video log" of Nordkap 476 - here is a video of the maiden voyage carried today with Adrian at the helm

Trying the fire fighting capabilities on a meths fired Macrocarpa leaf fire, (I forgot about the rotation function, which made it less effective,) but it still worked ok. On Board tank is only 500ml so doesn't last long.

I have taken the old wooden hatch cover off to find out what was inside there was something that moved around when you tilted the boat found the end of a hand made brass anchor and the remains of some sort of leaf or plant the joints are sealed with tar the inside has been carved out i find it very strange that the two items were sealed up inside i think it is very old possible the 1900
