Waiting For The Rain - Preparations Completed

Rain is forecast for the next 48+ hours - with some high winds, and cooler temperatures.

Normally I would just batten down the hatches, plug-in the small space heater, and make a hot cup of coffee.

In the past, weathering such events on the boat, over a multi-day period - would put me at risk of catching a cold - as I would periodically have to walk to the main marina building for the showers and the bathroom.

But these days - a cold, a sniffle, a cough - are high risk stakes on which to gamble your health - and, will subject you to banishment from almost every establishment / service venue (including the main marina building!!!).

So, I've decamped for the next three days to the harbor's nearby Holiday Inn Express - and will enjoy some finer accommodations, a luxurious bed, and a comfortable desk and chair.

I secured a new tarp to the deck, using six of my new 36 inch Velcro straps. Will have to go back and spot check it tomorrow and Thursday. The winds are forecast to be sustained at 30+ mph for a period here along the coast - with gust likely much higher. 
 
I suspect the Velcro will fail - but perhaps not. 
 
We'll see. 
 
My previous ad hoc use of misc. lines to secure the previous tarp were sufficient - but did not lend themselves to easy installation/removal. Tonight's install was a breeze.

2021-01-18 Monday - Researching Coremat

 This blog post is a placeholder as I gather links to information about coremat: 


  • https://www.carbonfiberglass.com/Foam-Core/coremat 
    • "Coremat is a nonwoven polyester that contains microspheres and is used primrily as a bulker mat or liner in composite laminates  that have been  made using a hand lay-up or  Vacuum Infusion as the means of production. Coremat should always be fully saturated with resin. The microspheres contained  in the Coremat will prevent excessive resin up-take."
    • "Coremat Xi By Lantor sets the standard for bulker mats. Resin consumption for coremat is approximately 600 grams per of mm thickness. It also utilizes a resin indicating compound that changes color showing that resin has been applied to the Coremat."
    • "Coremat Xi is very soft and pliable when it is wet is suitable for use within complicated shapes or molds."
  • https://www.carbon-core.com/
  • https://www.easycomposites.co.uk/coremat
    • "Lantor coremat is a traditional coremat or bulking mat used to quickly build up thickness in basic fibreglass moulds and components. The mat has a relatively high resin uptake but still lower than solid laminate, allowing thickness to be built up with less resin and less weight. Standard coremat is not suitable for resin infusion, vacuum bagging or RTM/lite."
  • https://fiberglasssupplydepot.com/Coremat-4mm-39.37-width.html
    • "Coremat® 4mm 39.37". Coremat is a random laid, shredded polyester material, which is soft in nature and conforms well. This materials is used for creating bulk in a laminate as well as controlling print. Using this material as a core is a cheaper alternative to solid fiber parts and the use of the core will add rigidity"

2021-01-01 Friday - Solutions for Fixing Leaks in Steel Water Tanks

 In this Facebook "Boat Refitting and Repair" group, a question was raised about how to fix a leak in a steel water tank.

https://www.facebook.com/groups/1236198593236295/permalink/1638421536347330/

 A few resources that I found, that may be of use:

    •  "J-B WELD WATERWELD: A hand mixable two part epoxy putty stick, that can cure under water and is ideal for repairing plumbing, fuel tanks, tubs and showers, drains, pool and spa, boats & potable water tanks and more! J-B Weld WaterWeld is certified by the NSF and is safe for contact with potable water. "
 

    • DAP Stainless Steel Sealant, Silicone, 9.8 oz Cartridge
    • "Commercial Food Equipment, Commercial Kitchens that Require NSF FDA Approved Sealant"
    • Meets: "2600 NSF Standard 51, ASTM C920 Class 25, CFR 177, FED.TTS-001543A, FED.TTS-00230C"

2021-01-01 Friday - Boat Toolbox: OSW Contour Gauge

I have a few projects planned for my boat that will greatly benefit by having a contour gauge.

I've ordered this one from Amazon
