just a quick update on the project
Had some luck surfing the net, managed to trip over a company that makes the gear for king crab boat. It has pictures of the gear and dimensions!!!

happy days!!... so i'm now drawing up the plans for the pots, pot launcher, block, coiler and sorting table in 1:50 scale.
still having problems finding any info on the cranes they use..if i have to fly to dutch harbour and measure them in person i will!!!!

The other option is to record deadliest catch and fish through the episodes (excuse the terrible pun) to work put the dimensions.
The other big development is that i may not be using the aziz as the doner boat.

it looks a bit large coming in at about 165 feet. The other option is the 4 or 10 hatch coaster by model slipway.

Coming in at about 150 feet. Not a lot i know, but the layout of the boat seems more suited to a F/V.
