Nearly Racing

I would like to think that we were in the lead, but we failed to make the start of the race - by about a lap, getting the boat ready from its winter storage, but it was light winds so we enjoyed cruising around the marks taking photographs of the racing dinghies

 

Weighing Dainty Too

 Setting up Dainty Too a being restored A-Rater Dinghy from the 1920's to be weighed. The boats have to be heavier than the minimum weight. Dainty Too Passed.

Safety Boat Course Day 1

Safety Boat Course

 ​ It was great to out on the water again. The weather was typical for February, but the promised rain was very light and only occasional. Six of us and two instructors wrapped up for the cold set off up river to learn some safety boat procedures. Heading up stream the boats were in formation, testing the powerboat skills of the students as we had to keep 4 feet from the boat in front and then speeding up the river line abreast.

Three Safety Boats out on the River​

As we went up the river the lead boat with the instructors in weaved around and turned circles with the other two boats trying to keep up. ​The crew swapped over the helm position, and we repeated the manoeuvres for all the students.

T6 Becomes a bath tub

The three boats were in line abreast, T6 at the end. The Dory T8 to starboard of T6 accelerated away to move around the bow of T4 creating a large wake. The Helm of T6 released the throttle and T6 lurched to a halt and the bow dipped as the bow wave came over us and the boat immediately became a bath tub with water up to my knees. We started bailing with the one bailer and the other boats came along side giving us their bailers  so all three of us could bail.

​As fast as we could it still took us 20 minutes to empty the boat. My next pair of waterproof socks will be over the knee versions or preferably waders.

Getting a Tow astern.

​Safety boat crews must expect to get wet. Following our impromptu bath we carried out many man overboard drills, pick up tens of bodies in the water and learning how to tow a safety boat that has run out of fuel. We learnt the advantages of dropping the anchor when in trouble and after  a hard morning work we returned to the clubhouse for some lunch before heading out again to rescue an Oppi, a topper and reversing onto a beach using the anchor. It was a great day out on the river and fun too. It is so nice when you can have fun and learn at the same time.

2. How to Deploy an Anchor

Deploying an anchor correctly ensures it holds securely and doesn’t damage the seabed or your boat.

1. Choose the Right Spot:

   • Select an area with suitable depth and seabed for your anchor type.
   • Ensure there is enough room to swing safely if the wind or tide shifts.

2. Prepare the Anchor:

   • Attach the anchor securely to the boat’s anchor rode (chain or rope).
   • Check that the rode is free of tangles and knots.

3. Lower, Don’t Throw:

   • Slowly lower the anchor over the bow to avoid tangling or damaging the boat.
   • Allow the anchor to sink until it touches the seabed.

4. Set the Anchor:

   • Let out the appropriate amount of rode, typically 3 to 5 times the water depth.
   • Reverse the boat slowly to allow the anchor to dig into the seabed.

5. Check the Hold:

   • Gently apply reverse power to ensure the anchor is holding securely.
   • Use landmarks or GPS to confirm the boat isn’t drifting.

3. How to Recover an Anchor

Recovering an anchor requires care to avoid strain on the equipment or injury.

1. Position the Boat:

   • Move the boat directly above the anchor using the engine to reduce tension on the rope.

2. Retrieve the Rode:

   • Pull the rode hand-over-hand or use a windlass if available.
   • Keep the rode clear of tangles and watch for strain on the line.

3. Break the Anchor Free:

   • Once the boat is directly above the anchor, apply gentle forward power or rock the boat slightly to break the anchor free from the seabed.

4. Clean the Anchor:

   • Wash off any mud, sand, or debris before stowing the anchor.

5. Stow Securely:

   • Secure the anchor and rode properly to prevent damage to the boat or injury during transit.

The Second Flood of the Autumn

The fog moves in over a frosted path The river is rising, approaching the path.

 The Second Flood and its still November

The river is bursting its banks again, and it is only November. The water flow seems to have reached its maximum of 148m3 per second, and because the flow rate cannot increase much beyond that, the water levels rise. Over the past few days, the waters have been rising and are now over the Thames Path.

A bright Autumn morning looking over the River Thames in flood. The water has risen about 2 ft and is now covering the Thames Path outside the Upper Thames sailing club. The water has a harmless glassy look and looks calm even though the water is racing beneath the surface. The trees on the opposite bank are reflected on the water's surface, but the pontoons next to the bank now look like they are in the middle of the river.

This is what the water level is like in flood and what it should be like.

The waters rise over a few days

Taking a look at the water starting to rise Monday to Wednesday after storm Bert came through

Monday morning sees the Thames over the Hrd and starting to eat into the grassy verge. Fluffy white clouds are in the sky.

A dark grey cloud looms over the River Thames, yet the rest of the sky is bright blue. The water is rising up the bank on this Tuesday morning and the black foot marker is half covered.

I'm watching the river rise on Wednesday. The water is moving up the grassy bank, and the black foot marker of the Pole has nearly disappeared.

No sailing for a while

 

Looking over the flooded River Thames this morning, I see that the path has gone, and I feel there will not be much sailing for a while.
