Unsurprisingly it wasn't well attended, I bought a few things: Elastic bungy cord sail ties (the type with a ball at each end); 10 for a fiver, some 3mm cord (2 rolls for a fiver) and 20m of 8mm rope for £6. The 8mm rope was marked up at £14 but I think the stallholder had had such a miserable day with so little interest he just walked over and said £6 for that. I guess he was happy to sell it at any price. So I bought it. lol
Walking through Havant to the train station in the Sue Ryder shop window there was a dinky little Barometer/Thermometer/Hygrometer set on a wooden plinth. For £5.95. I bought it and I'll put it on the boat.
By the way, I did say train station. Yesterday I used public transport. Mainly because it's a huge trip round Portsmouth harbour to get to Gosport, plus the traffic is horrendous over that side due to there only being one road in and out.
Far better to walk the half mile to the train station, get off at the other end at Portsmouth Harbour right next to the Gosport Ferry and then walk the half mile to the Boat Jumble. It did stop me buying some bits. Like two very large fenders that were marked up at £7 each and I could probably had for a tenner, but they were just a bit too big to carry. Next time I'll take a big rucksack.
