Thanks for those replies.
There were hundreds of T.I. luggers built, one builder alone built over fifty. They weren't pretty boats and were built to be a platform for the pearl divers, who did have a hard life, one in ten died from shark attack, the bends or accident.
The reason for the build is that a friend whose family was involved in the pearling industry wants to have a go at building one.
The Model Boat/Sarik plans are for the sail plan only, unless I've not got to the right plan.
I have contacted the Australian Register Of Historic Vessels and am awaiting a reply.
The Queensland Maritime museum has one of the T.I. boats , I don't know if they have plans for it .They are usually very helpful there . I got plans for my tug Forceful from them years ago. I'm awaiting a reply from them.
Regards Peter
