Dumas kit 1233 1/30 33" is the newest upgrade of their old PT 109 kits. Larger scale Dumas are mainly for RC. It doesn’t really matter if your building static.
If its an old kit it will have wood sheets for the hull. The kit is plank/sheet on bulkhead, So the new kit comes with PVC for hull. I don't do PVC or solid hull, and do not really care for plastic. So, I replaced all the PVC with Mahogany sheeting. It is a good kit, but very basic lacking in allot of detail Everyone’s different, but I chucked the instruction book, the plan sheets are good. Did not use the PVC or the cast parts, 80% of the build is scratch built following plans on Jeff D’s PT103.com and Gene Berger’s build site, both have been great help. For me the bottom line was its hard to find a POB wood PT in larger scales, Dumas is a good company, so this kit is a good foundation for a PT build, I just wanted to take the build much farther than the kit presented, as far as my build log goes I have went back and upgraded allot of areas, after getting more info from Jeff D and the experts at ptboatfourm.com Again if you want to build a PT I highly recommend these sites
