Should the bunks take most of weight, or rollers?

Hello everyone, I was logged on before as Lurcher but site problems caused change, I have now had boat in water where I was able to change last roller (rear one) all new rollers, I notice that on my trailer the bunks take most if not all of weight, this is proved by being able to rotate the rollers slightly, I did notice a fair amount of effort winching the boat back on over the bunks, although I was not in deep enough water, I was wondering if I should put a spacer plate under the rollers to bring them into more contact with the keel, the trailer is original one for boat, I just replaced the rollers with original items, in deeper water will boat settle over bunks easier, I do note on other questions here that it is recommended the bunks take most weight, the bunks marked under the hull by me pushing boat off without enough water, should I leave bunks to take weight or pack up rollers, to adjust the bunks at this stage would be a mammoth task as the threads on the inner ones are corroded, (job for winter) thanks again JBD

Depends on your boat, deerhound.

Where is the strength? If it is in the keel put the weight on the keel rollers. If it is a stringer build put the weight on the bunks.

Thanks JB, fine point, I would say strength just maybe in the stringers, it is a speedboat 15.5ft with shallow almost flat hull, it has reversed stringers and looking at it from front is like 3 hulls on top of each other (if that makes any sense) the slope of bow is very sharp and the boat can be lifted at front fairly easy when on trailer, I would imagine that if water is correct depth boat should sit on bunks without any great difficulty? will try and post picture. thanks again, JBD

Check with the mfg or a dealer of the boat, they will tell you which is best for that boat.
