Ahhh.... I thought you didn't like my dirty tubes with fish guts and blood all over
The Searider is definitely worth it. I honestly would not worry about the tubes, not only because Avon tubes are known to last a long time but also because ncp's tubes were well taken care of and refurbed with new rub rails. There are professional tube makers on the forum and they can give you some info also if you want to ask on the main forum. Send ncp a message, he will tell you about the trip he just took on that rib..further out than I have been.
The Avon SR5.4 is popular over across the Atlantic but not too many people know about them over here. It can handle more than my Zodiac because it is a bit narrower and has a deeper V hull so the ride will be more comfy with less slap in the chop. The hull also has a water ballast system that makes it very safe and stable when at rest.
