Yet another Speedline Tamar
November 2013 I received a large packet from Adrian Gosling, and somewhat frightened over the prospect of a first time building in perspex I started building in January. I have been impressed by the attention to detail and precision of the perspex, percy and brass parts. Now the electronics and exterior are finished, and I can’t wait till sailing season here in the Copenhagen area begins. I still have time to finish the interior! It is named “John D. Spicer”, RNLI No. 16-24, stationed at Porthinllaen. It is fitted with two brushless 340 kv running at 12-24 volt. The transom, mast and antennae are manoeuvred by hydraulic. The radar is driven by a 6 mm planetary geared motor. The windscreen wipers are not true to scale, but they work. I want to thank all the enthusiasts at the Model Boat Mayhem for many good advices and hints. I also want to thank Mr. John Falvey for his kind reception at the Barrow Lifeboat station and the many good pictures of the Tamar class “Grace Dixon”.
I place some pictures here from the building and link to a video on Youtube:

That's fantastic workmanship. I'm envious of your mast, ariel, transom door and windscreen wipers; I've never been good with electrics. Lovely to see thank you.

Nice job and a very quick build especially with all those working bits. Could you possibly share with us how you got it all to work.

Thank you for all the nice comments, they make my efforts worthwhile :-) !
As mentioned, I used hydaulics for the mast, antenna and transom, below is a picture of the installed hydraulic pump and servos, behind the motors. I am not sure I would choose the hydraulic solution again, mostly because of the messy oil. In order not to disconnect the hydrarulic tubes each time I want to acces to the interior, a cradle for the deckhouse is mounted beside the boat. The deck above the Y-boat is opened by a linear actuator. In the picture below, the motor in the middle turns two threaded rods, of whic one is left, the other right threaded. Thus the actuators goes in opposite directions when te motor is running.Next is a picture showing the simple solution for the windscreen wipers. A small, 3 v motor doing 36 rpm push/pull the bowden cable inside a brasstube. On the cable, at the right spot under the window frame, a rod is soldered, moving the wipers. Finally I can mention, that the top of capstan on the rear deck functions as main-switch, turning a 3-poles rotating switch located beneath deck. :-))
