NB: Relevant Atalanta trailer drawings available from the Drawings Library are:
- B19564 Principal dimensions of Atalanta trailer
- C24595 Atalanta Mk 2 Chocks for road trailer
- C24703 Atalanta principal dimensions of alternative trailer
- C24826 how boat is secured on trailer for hauling out
Original Atalanta trailers are likely to have been modified over the years; like the one I inherited with A 169. As you can see in the photo above, the original front section has a central box girder running forward to a galvanised towing hitch and dolly assembly. The original trailer was cut-off and re-welded to the replacement matrix arrangement.
This has posed a few problems for the refurb:
The original trailer drawings (B 19564 / C 24595) have the forward chock (wood -Fairey drawing version) full width on the trailer frame. As A169’s modified frame is some 250 mm narrower the chock had to be re shaped; fixed with bolt screws and bracing. No issues with the centre and aft chocks – were remade to the drawing specification – 20mm compressible padding under neoprene top covering.
Aluminium docking arms (guide tubes) were made to the Fairey drawing spec; the aft ones were OK, but the forward arms needed some re welding to increase the width – not sure if this is due to the trailer mod’s; or interpretation of the Fairey specification. Anyway, they are fine now – with enough clearance for padding to protect the hull/strake.
Having acquired an old 16″ “Rice” trailer spare wheel (as on the original trailer); am unable to mount this between tow hitch and forward chock as per the Fairy drawing as the dolly winder is there (on a welded bracket). Still scratching my head on where to fit the spare wheel.
Apart from these glitches the trailer refurb is almost completed – just an overhaul of the wheels and tyres before use on the road.
