Hello again Roy,
I tried searching for info about this model a few times in the past but sadly there is little available on the web, and on this forum. I have heard that it is pretty easy to build and that it makes a very nice model when finished. Looking at Caldercraft's photo of the boat I would say that it would be a straight forward project without too much complexity. If it were me I would buy this kit regardless of whether the instructions are good or not. It's just such a nice looking boat and not expensive! And if you get into difficulty just post your query on the forum; there are so many skilled boat builders here that they would solve your problem in a flash! You could also join the "Trawler Photos" website and post something there, plus research the Fifie as a vessel.
Good luck!
Simon
PS - I've just been reading your other thread on the forum about your first boat kit. Again I would agree with the others about model boat shows as a good starting point for info from the suppliers. But again, I think you will find the "Amaranth" a very good first kit. Even though it is a herring drifter, the principals of powered RC model boat building are pretty similar across the board and any problems you discover will almost certainly have been solved before by our knowledgeable army of boat enthusiasts here on the Mayhem forum! I would say take the plunge buy the kit and then read the building threads (such as hull preparation, motor and RC equipment installation) here on the forum; everything you need advice wise can be found at Mayhem! Action Electronics are brilliant for RC gear and wiring diagrams; have a look at their website.
