I have a set of pacific 24 tubes for sale from an ex mod/police vessel.
Tubes are in moderate condition with the foremost 5 chambers holding air well and the aft chambers with moderate leakage. They will hold air for around 12 hours then be soft. Leak is located behind rubbing strake so would probably be an easy fix if one had the time / knowledge/skill.
Tubes have been sent to manufacturers whom have quoted for full refurbishment which could be arranged .
Picture is from a few years back however tubes have been inflated , under cover and ashore since then.
