Most of our builders are amateurs, and we're proud that with our help, and that of our involved community of owners have turned out very nice and useful boats. It's a very rewarding activity.
... but it's not instant gratification.
One of our 8' prams could be constructed in as little as 40 hours or as much as 120, depending on the level of attention to final finish. (We have found that the best way to make a boatbuilding project rewarding is to do as neat a job as possible early in the construction so as to minimize sanding and fairing at the end)
One of our 18' Pelicanos might take between 150 and 300 hours, depending on skill and attention to detail.
