I have ballasted the boat over the weekend and she had her first sailing this morning.

She sits well on the water and handles as expected. The wave formation at 1/2 to 2/3rd throttle looks good for scale speeds with plenty of resreve power. Now it's on with the deck fittings and transforming the white 'blob' that is the superstructure into a finished boat.

The gearboxes were some old stock my local model shop had, they are made by Irvine and were for 500 size motors. Brass pinion for the motor and steel main gear. I think they were for early electric flight models.

I have now fitted the 'sampson posts' at the bow and stern and they are strong enough to lift the model complete with full ballast and lead acid batteries. :-\ The deck ventilators have been fitted and the first coat of grey on the deck done. I have also made and fitted the stanchion support plates on the raised bulwarks and started to fit the shortened stanchions. The display stand for the boat has also been made and the finish is based on the RNLI colours of the period. The side stanchions and the access hatch on the foredeck will be made and fitted soon.

You are doing a great job. O0 One question, what are the holes in the keel for? I notice that there are some both bow and stern.

they are called Ruffle holes, and were used to secure and haul the boat up slipways with. the stern holes for hauling up, and the bow holes had chains passed through with slip releases that were hammered out when the boat was bing launched.
hope this helps. neil.

OK I understand now, instead of being tied to a dock and ready to go, they were kept in a boat house and slid into the water as needed. Is this correct? Why was it done this way?

Lots of places there just isn't room to keep the boat afloat, if there's a rocky coast for example.

e.g. St. Davids.  http://stdavids-rnli.org.uk/rnli3%20station.htm

Hi Andre,
There is a very long history involved in the RNLI dating back to the 1820's and far to involved to go into infurum.
However, the main crux of the matter is that the history places many boats on the sea shore, and there were two basic types of launch in the early years (not counting those which had to be kept afloat in a harbour for topographical reasons) and these were:
 
1) the carriage launched boats, where boats were kept on a carriage and drawn to the gently shelving beaches and tide which had receeded too far out at low tide.These carriages were drawn by *(usually) horses ( and later motorised tractors) and are still used at stations such as Lytham St Annes,Lancashire, Wells Next the Sea,Norfolk

2) the slipway launched boats where the topography and geography and state of tides allowed the Quick launch into seas at any state of the tide.However although there are still a number of stations which still operate slip launch ( Cromer in Norfolk and Roa Island, Peel, Walney, and Douglas Isle of man just to name a few, more and more boats in the modern RNLI are now being kept afloat.

However, all those carriage and slip launched boats needed somethiong within the hull which would allow them to be able to be dragged either back onto the carriage or up the slipway after recovery and then to be tethered either to the carriage or on the slip, and that is why the boats had ruffle holes.

As for being kept afloat, at some stages of a storm with on shore winds driving into a harbour it was at times quite immpossible to "launch" a lifeboat, especially either a pulling/sailing boat ( without engines) or the early single screw motor lifeboat that had very little power, ant this could be trecherous, as shown in 1953 wein the Arbroath Lifeboat ( a twin screw Liverpool class) was capsized at the harbour entrance with the loss of 6 of her seven crew, and so the slip launch gave that extra momentum for the boat to gain sea way before she could be overwhelmed by mountainous seas.Harbour entrances are notorious, in foul weather, to negotiate.

That is not to say that the more modern boats don't have similar addition, as the new Tamar class, the Mersey and the Tyne class all have a type generic to their own hulls, but not quite as pronounced.
Hope that helps.

If you want to know more about lifeboat design, I would suggest you go to your local library and borrow two books which have a much greater knowledge than I could ever have, and they are:

1) Lifeboat Design and Development by Eric Fry, and
2) RNLI Motor Lifeboats, A centuary of RNLI Motor Lifeboats  by Nicholas Leach

Both superb books and well worth a read.

Neil has provided an excellent answer and recommended some good books.

I would like to add one more book which really brings the history of a lifeboat into its full glory. The book is very well illustrated with many pictures, drawings and maps.

"On a Broad Reach: the history of the St Anne's-on-the-Sea Lifeboat Station 1881 -1925" by G I & J E Mayes. £12:50
ISBN 1-902953-01-0. This book may only be available directly from the small specialist publisher, try Email: bmccall@globalnet.co.uk

Lance, Niel and Rodger,

Thanks for the information,  O0 it explained how they were launched. I went on to U-tube and there were a few videos of both the carriage and the slip way launch. The slip way launch in a storm would have been a ride to make your local amusement park green with envy.  I will try and get the two books that you mentioned Neil but in the great pacific north west (Portland Oregon) I am not sure that they will have them on their shelves. But worth a shot any way.

I understand about a river mouth in a storm, here in Oregon we have the Columbia Bar at the mouth of the Columbia River. It is reported to be one of the worst river bars any where in the world for rough water and we loose one or two fishing boats a year there. The US Coast Gard has their rough water training school for small boats there. I have seen some of the videos of them training and some day I would like to go along just for the ride.

Thanks again for the responses,
Andre :)

Getting back onto the subject of the build, I have made and fitted the anchor support arm that sits on the starboard side of the boat. This along with the hull protection blocks  has now been fastened in place and are ready for filling/ painting. The anchor is a white metal casting that I have slimmed down and 'improved' in shape. This will be held in place on the arm with a release pin through the holes in the arm. The end shackle and anchor chain will be fitted later.

ANDRE, These two books regularly come up on ebay, and usually at a reasonable price, so keep your eye out for them.
Roger ,thanks for that one, about the L.St.A book. coming from the Fylde coast, I have not seen that one so will keep my eye open for that one to. cheers,neil. O0

I have now fited all the stanchions onto the toeboards and they now need painting light grey before the chains are fitted in place. The two either side of the anchor have had their modifications done to allow the chains to avoid the anchor. The distinctive red, cloth covered Watson bow fender has also been made and fitted in place.

After the sucessful 'sea trials' of last week the boat has been 'accepted into the fleet' by the addition of her name on the bows and her station on the stern. The covers for the outboard end of the scuppers have been made and fitted in place. The anchor now rests in place on its mountings with the anchor chain fastened to the stanchions to keep it out of the way and its cable entering the hawse hole. The stanchons have also had all their chains fitted. The hatch and minor deck fittings are under construction and the grab ropes will soon be fitted to the outside of the hull. Next major build section will be to take the dremel to the lump of grp to start turning it into the superstructure.
