A Perfect Winter's Day

A very rare week day off work and perfect weather for a winter's bimble in the lowers reaches of the Bealieu River.
Who said Friday 13th is bad?

Anoraks & Bridges

Here's one for the nerdy "Anoraks" amongst us!

Sunday's paddle was programmed to be Eastney to Portchester around the north of Portsmouth via Portsea Creek. The route would take us alongside the very noisy M27 motorway under three of the bridges connecting Portsea Island to the rest of the UK! The railway bridge to the east and the two bridges under the A3 Hilsea Roundabout to the west.

HW Portsmouth on Sunday 8th Jan was due to be around 1030 (possibly 20-30mins later at the top of the harbour?) As this would be around the time we arrived I thought I'd better cycle over the day before and check the air draught (Clearance) under the bridges.

So here it is:- HW Portsmouth 0948 Height 4.4m Weather: Southern England under a ridge of high pressure approx 1020mb (high pressure depressing tidal height and possibly delaying the time of high water?)

What do you think? Should we go or not?

Railway bridge at the east- HW +20mins. Plenty of clearance under the north span. No real tidal flow.
Eastern Hilsea East Road bridge - HW +30mins. Clearance touch and go sitting upright in a sea kayak? If it was low pressure the water would be higher. As a guide, if the plinth in the low foreground is just covered it's a definite no go (water 25cm higher)
Same as above - close up. Note the west going ebb already starting at the right hand edge pillar.
West Hilsea Road Bridge - HW+ 40mins. Good clearance on this newer and higher bridge. Note the strong west going ebb already producing a big eddy at the right hand edge pillar. (I estimated it to running at 1.5 - 2knots when I went back past the bridge 5mins later!)
What did I do? I changed the club paddle to a much quieter outing (no M27 motorway) in Chichester Harbour! One of my fellow paddlers on Sunday reckoned that a tide height of 4.2m was the highest tide you could get away with - I think he was right.

Blow Away the Cobwebs- Club Paddle 28 December

Weather forecast SW5-7 becoming NW 5-7 possibly 8. It didn't look promising for the 'round Hayling paddle', but the sea didn't look too choppy, so we set off along the seafront. In fact, a part from the odd gusts, it remained at 5 all day and even dropped to 3 at convenient moments on our up wind leg. Everyone found some waves to enjoy, here Liz finds a nice piece of chop. Chichester entrance did have the odd large sea, but the tide was just high enough for them not to be breaking too far out. The tide carried us swiftly to Langstone bridge. However, it ended badly for one paddler, his knee buckling sideways under him as he slipped launching the boat from the slippery concrete slipway after lunch. Something we had not practiced in our Monday night sessions, but will do so next year; recovering a floating paddler who has lost the use of one leg on a treacherous surface with no alternative way out. The boat had to be left in storage with the beer kegs as the remainder of the group completed the paddle back to Eastney. The emergency services were initially suspicious; a sea kayaking incident in a pub car park?

Saturday 12 November

Summer sunshine at No4 Bar buoy. Safely across to the small boat channel before a fastcat leaves Portsmouth. The Mont St Michel creeps up behind us in the harbour. The sunshine disappeared later in the afternoon and it was Winter before we reached Eastney again. Finally the evening pool session at Eastney. Come on Club bloggers, get blogging.
