Hi Mike, with the planking strips (bit lazy there) I buy those generally from 'Modellers Shipyard' in Australia found them to have very good quality lime wood ,have bought some from the UK but found the lime wood strips very splintery and softer, all the other deck beams etc cut those on the band saw.
With this set of photos are of 2 crane kits i bought from the UK, one from 'Model Slipway' a power block crane FK-OL ,even though this kit is scale of 1:24 and my models are of 1:16 I wouldn't want this any larger, and the second crane kit is from 'Macs Mouldings' a Seacrane M321, I made some slight modifications on them but very impressed with their realism and outcome of both of them.
With the aft power block crane i made a slide frame on the trawl gantry to make it easier to remove etc.
