Hello,so I bought a 15'tri-hull and it came with a trailer that's quite shabby at best,I am a fabricator/welder so I am in the process of beefing it up but my ? Is about the rollers on a 15' tri-hull what is the ideal setup,also it looks like this is a tilting trailer,I have never launched a boat from one of these,is it ant different from a normal launch?
