RE: 85 ft Harbor Tug/Angels Gate
Hi Steve,
My tug was built from Francis Smith plans and there are a few pictures of the drive system posted earlier in this thread ( #22.27,34) and I have many more that I can send you of the actual hull construction.
As Tug said, it really isn't a difficult build but it does take some time to lay up the hull. The best advice Francis offers is to make sure you start with a solid jig and lay the hull equally on opposing sides to avoid warping...I didn't follow this advice as close as I should have and suffered a small warp but nothing that is noticable or hurting performance.
It's a great project though, good luck with it.
Keith.
