Hi not seen that kit you mention, but had a good look at the paddle boat kit they also make and the wood quality is good and the laser cutting excellent. The detail of parts goes right down to the small items in the dining saloon.The fittings are resin and not my favourite but quite common now. You may also find this kit under other names Modell-Tec and Nordic.... sorry can't remember the rest of the name.
The build instructions are all coloured and well printed, looked good to me. I did not see a full size plan, can't blame them for that as I have seen rip off kits from China based on boat plans published here.
The only down side for me anyway was the additional drive parts for the paddles. This was an excellent metal drive worm that aligns with a resin purpose made gear wheel, you do at least get 2 of them. Make your own mind up on that. I would have used a motor with a gearbox and a neoprene drive band.
However, if I did not have a backlog of boat builds I would be happy to purchase this kit as it saves so much time in the building with all the laser cut parts.
regards
Roy
