I have been looking at several options for a useful tender for a say 65' trawler. Are there any differences between upkeep between a rib tender vs. a complete fiberglass hull boat? I know that the weight difference is huge. We are looking for something that can both transport guests to shore, do some skiing, maybe bay fishing, scuba diving....but nothing out in the deep blue. We would use the big boat for that. Is one more stable than the other in terms of ride quality, at anchor, sea spray etc? I think something in the terms of 12-16' in length with a certer console, with room for say 5-6 people.
