That hull picture reminds me of my first attempt at boat building earlier this year.. I started with a red fibre glass hull from ebay
I set out to build a large scale fishing boat from it, much to the amusement of some that saw my intentions... After spending hours trawling the net looking for likely candidates I decided to loosely base the model on a "Westral"
I bookmarked as many pictures of the original from different angles and set to work with plywood and plasticard.
At this point a few people said the motors were to small but they are the same as in an Aziz tug model which has a similar size hull and weight.
After a few weeks of chopping plastic this is how she looks on the water and she handles a treat.
The entire build was recorded on my blog

Having built my first boat the next challenge is ongoing ... A kit boat !
