Bingo Nos. Bingo.
Not the starboard tubes that goes soft, but the front tube that hasn't needed pumped at all.
Hand pump not enough to get it out, but pressed the deflate thing by hand and water started pouring out until it was only in starboard side. Nobody around to give me a hand to tip it over so that it lies the other way, so I'll wait on the tide.
As matt said earlier about the propensity to lie to the starboard, this put all the water on that side of the tube (its a u shape at front and a straight one each side for those unfamiliar with this rib).
Strangely , I did the taste test, and fresh. How on earth did it get in? And how do I stop it happening again? Remember this tube is firm and airtight.
Re steering, as tube was deflated and I had right size spanner, I unscrewed the alloy nut and it was very free to turn by the wheel. Will remove totally and regrease when I have the right spanners and grease with me.
