SUMMARY:Zoom Mtg. No. 7 - Experiences with Anti-Fouling Treatments
DESCRIPTION:This meeting will provide an opportunity to exchange experiences with antifouling paints and possibly other ways to inhibit underwater fouling. At a recent Zoom meeting several of those present indicated that they would be happy to contribute to this so if you can tell us about your experience\, good\, bad or indifferent\, with a particular antifouling treatment in a particular geographical area please do tell us about it.\nAs an introduction to this meeting\, there appear to be five main types of antifouling treatment as follows: \n\nSoft Antifouling paint\, also known as eroding or ablative – the whole thickness of a biocide impregnated paint coating slowly erodes. This reduces the need to remove old paint before applying new. This is the most widely used kind of antifouling paint today.\nHard Antifouling paint – biocides dissolve out of a paint base which does not itself erode to any great extent. Requires removal of old coatings before re-coating. Can be sanded/polished to gives a smoother lower drag surface than most soft antifouling paints although ‘self polishing’ soft paints are intended to combine low drag with reduced need for coating removal.\nPaints relying on non-stick properties rather than biocides\, generally silicone based. ‘Aquacote’ and Hempel ‘Silic-one’ are examples. Slime forms on the hull but is relatively easily cleaned\, possibly while the vessel is afloat\, or it is removed by sailing at speeds over 8 knots. A fairly recent development which is not yet widely used.\nCoatings\, generally epoxy\, in which are encapsulated particles of pure copper. Occasional light sanding exposes fresh copper. I think copper ’tiles’ for bonding to a hull have also been available. Also\, at least one yacht has been built from copper-nickel alloy which has inherent anti-foulding properties.\nMethods that do not use any coating on the hull – ultrasound\, electrolysis or a giant bag enclosing the hull of a moored boat with treated water within the bag.\n\nIt would be good to hear of peoples experiences with the various options\, particularly those options which may become the only options if copper based anit-fouling paints are banned.

SUMMARY:Zoom Mtg. No. 6 – Power from Natural Fluid Flow
DESCRIPTION:For this meeting AYRS member Tom Potts would like to tell us about an idea for generating power from natural fluid flows which could be the wind or water currents or possibly even wave action. He would like us to discuss this and add our own thoughts to see what we come up with. I am hoping that he might also tell us a bit about Cornish gig rowing. \nAt our last Zoom meeting I sugested a change to the day of the week for these meetings since in the UK at least\, limited outdoor recreation is now permitted\, so on Saturday evenings some of us may be returning from a day out boating.  However\, after a short discussion the consensus at our last meeting was to stay with Saturday meetings for the time being\, so our next meeting will be next Saturday evening. \nComing up soon we plan to have a Zoom meeting about anti-fouling treatments and a meeting at which Bernard Rhodes from New Zealand will tell us about the design and construction of the 21 foot trimaran which he sailed across the Atlantic and Pacific oceans back in the ’70s. \nOur announcements are now being sent out to AYRS members through a Mailman list (https://list.org/).  The way that we first had this set up meant that replies from individual members were being circulated to the whole membership which resulted in members receiving unwanted messages\, so apologies for that.  I hope this has now been corrected – I am sure it will very quickly become obvious if it has not.

SUMMARY:Zoom Meeting No 4 – The 'Paradox' - a 14 foot cruising boat
DESCRIPTION:Paradox miniature cruising yacht (in Salcombe harbour)\nAlastair Law will tell us about building and sailing his 14 foot (4.27m) sailing boat\, an example of the Paradox design by Matt Layden. (www.microcruising). \nAlastair’s boat\, ‘Little Jim’ was the first Paradox to be built in the UK. Alastair has sailed it extensively on the south and south west coasts of the UK and finds it ideal for his purposes. \nThe Paradox design is: \n\nSeaworthy for estuary and coastal cruising.\nBetter able to protect its crew from adverse weather than most boats of this size – can be sailed entirely from ‘down below’.\nRobustly constructed – strengthened underneath to take the ground.\nAble to carry a lot of provisions and equipment – Alastair caries an inflatable tender and a folding bicycle on his one.\nComfortable for a solo sailor to spend time on board\, including overnight.\nReasonably easy for transport by road trailer.\nFaster to windward than many people would imagine that it could be.\n\nBut its not a boat for family sailing! \nSee under ‘website’ below for the link to join this meeting (actually the same link as for our previous Zoom meetings)  No password required to join the meeting\, just click on the link a little before (say a few minutes before)  the meeting start time or if you need the meeting reference number it is the 10 digit number at the end of the link.

SUMMARY:Zoom Meeting No 3 - Building a sliding seat rowing boat
DESCRIPTION:At our previous Zoom meeting John Perry covered the design for a sliding seat rowing boat and showed video demonstrating the design features.  For this follow on meeting John will describe the construction of the boat and include a few pictures of the boat in use.  This will be a slightly shorter presentation than last time\, so there should be good opportunity for questions and discussion. \nNote that the time of this meeting is later in the day than the previous meeting – this may make it easier for members on the far side of the planet.  (the time given for the meeting is British Summer Time) \nFor the link to join the meeting see ‘event website’ below.  (the link is the same as for our previous Zoom meetings)

SUMMARY:Zoom meeting - Design & Construction of a Sliding Seat Rowboat
DESCRIPTION:Design and Construction of a Sliding Seat Rowing Boat \n– presentation by John Perry followed by questions/discussion \nThis rowing boat was first launched May 2017 and since then has had frequent use on the estuaries of Devon and Cornwall and also camping trips on rivers in the UK and France.  These are some of the features: \n\nDesigned for a single rower with or without a passenger\, this required two rowing positions to maintain longitudinal balance.\nFolding outriggers allow coming alongside quays and lock walls.\nStorage space for camping equipment.\nDetachable wheels for launch/recovery and for portaging.\nArrangements for easy loading onto car roof rack.\n3mm plywood construction with external glass epoxy sheathing\n\nFor those who are not familiar with Zoom: \nTo join the meeting wait until a few minutes before the start time then click the link provided in this meeting announcement (under ‘Website’\, below). If you already have Zoom software installed on your computer or other internet device then your email client should then direct you to Zoom when you click this link and you can then join the meeting. If you click the above link but you don’t have the Zoom software installed then I think you will be prompted to download and install the software before you can join the meeting so it is probably best to already have the software installed before you try to join Zoom meetings. You can get the free Zoom software at www.zoom.us/download – the software you need  for a Windows or Apple computer is the top button in the list\, it is labelled ‘Zoom Client for Meetings’.  If you want to use Zoom on a smartphone there are Zoom apps available for Apple and Android.    Zoom can be used with almost any device capable of accessing the internet but it probably does work best on a computer since a larger screen will give you a view of everyone present. \nBeing in a Zoom meeting you can almost forget that you are not in the same room as the othe participants.  You see the other participants and can talk to them.  The ‘mute’ facility is quite important\, when you are not speaking to the meeting is a good idea to mute yourself so that background noise from your environment is not transmitted to the meeting but remember to unmute yourself if it is you who are speaking to the meeting!  When a presentation is being given the host may mute everyone except the person giving a presentation. \nWe are grateful to one of our members for hosting our Zoom meetings on a commercial account\, this means that we do not have the time limit that applies to free accounts.

SUMMARY:AYRS Zoom meeting
DESCRIPTION:Last weekend we held a first trial Zoom meeting for AYRS members in the south west of the UK.  For this locally based meeting we had no prepared agenda\, we just introduced ourselves and chatted about our boating interests  This went well\, so our next meeting is open to all and this time we will try having a more formal agenda – \nSo: \nAt 16:00 (London time) next Saturday AYRS member Kim Fisher will present the ‘Rescue Float’ project that he is carrying out in collaboration with AYRS member Chris Watson.   \nBriefly\, this is a project to develop a craft for use by beach lifeguards. Some beach lifeguards today are using surf boards\, others have RIBs or jet skis. The Rescue Float is intended to fit somewhere between these options – it is more suitable for carrying a casualty and possibly administering first aid than is a surf board but it is cheaper and easier to launch than a powered craft. The AYRS had a fine looking stand at the recent RYA dinghy exhibition and the ‘Rescue Float’ was the centre piece for the stand and attracted plenty of interest. \nQuestions can follow Kim’s presentation and we may also have some discussion about the way forward for any future Zoom meetings. \nThe link to join this meeting is below\, under Website.  If you need the meeting reference number it is the ten digit number in that link. \nFor those not familiar with Zoom: \nZoom is a video conferencing system that has been recommended to us by an AYRS member who works at the University of Plymouth – he has been using it regularly during the pandemic to give lectures to groups of up to about 70 students. \nIf you already have Zoom software installed on your computer or other internet device then your email client should direct you to Zoom when you click the link for the meeting\, allowing you to join the meeting which you should do a little before the published start time. If you try to join too early you may be asked to wait\, and you may be able to chat to others who are waiting for the meeting to start.  If you click the link but you don’t have the Zoom software installed then I think you will be prompted to download and install the software before you can join the meeting. Hence it is probably best to already have the software installed before you try to join Zoom meetings. \nYou can get the (free) software at www.zoom.us/download. The software you need for a Windows or Apple computer is the top button in the list\, it is labelled ‘Zoom Client for Meetings’. If you want to use Zoom on a smartphone there are Zoom apps available for Apple and Android. Zoom can be used with almost any device capable of accessing the internet but it probably does work best on a computer since a larger screen will give you a view of everyone present. \nIf you are listening to a presentation in a Zoom meeting it is probably best to ‘mute’ yourself so that any background noise in your surroundings is not conveyed to the meeting. However\, you need to remember to ‘unmute’ yourself if it becomes your turn to speak!
