  1. Apologies for the delay in answering, life got in the way yesterday. I know on the face of it this sounds out of the norm. We are buying a canal boat and want to travel the inland waterways of England for 3 years. Over the 3 years we intend to fit out the interior of the canal boat to our liking, making it a home. We then want to low load it back to Penryn where we currently live and have it put in the water at the top of Penryn river. Then we intend to live on it. The reason why we want to do this is purely for space reasons aboard. The equivalent length motor cruiser or yacht doesn't have the same internal space due to their configuration. We have haulage interests in our family and also mooring interests in Penryn so the the logistics of putting into the water aren't a concern. So this question was purely about the dynamics and potential problems of a flat bottomed bottom sticking to tidal mud at low tide. I have had so very good answers to this potential problem, including yours, thank you. You are exactly right Tony. Except we don't intend for the boat to move. In essence it will become a house boat.
  2. Thank you all your insightful answers to my question. It certainly has answered a lot of my questions and given me some ideas and food for thought. Hopefully I will be able to come back to here in a few years time and let you all know how it went. Happy and safe boating to you all.
  3. That is a good idea, better idea though to send the wife in to investigate haha. The concrete idea has legs too. This is 3 years down the line at the moment. We are looking forward to travelling the inland waterways first, that'll give us time to investigate all of the estuary options.
  4. That is an interesting plot indeed. Quite a distance travelled too over that time period. I can only answer how the tyre option for me would work. On the Penryn river where I would intend to permanently moor, it is literally right at the top of a tidal creek. The boats bow is tethered to the path along the riverbank and the stern is moored to a permanent concrete mooring block a few feet behind the boat. This only allows for a very small drift factor and as the out going tide would pull the boat towards the same direction every tide, the place of rest on the estuary mud would be almost the same every time.. well this is the theory but as we all know, theory and practice are never quite the same in the boating world haha.
  5. LOL Haha.......the expense just keeps rising lol
  6. Good question but this won't be a problem because where we have in mind is a riverbank mooring so we would just use a gangplank o0n and off the boat. This is a very good question. I am using my bar of soap stuck to the sink equation on this lol but yes, a little more science may be needed I feel.......that bar of soap though don't have stick to the sink haha.
  7. Hi Blackrose, great photo by the way. Yes, if it was shingle/gravel as it is in your photo then it wouldn't be a problem but the whole of Penryn river is thick oozy mud at low tide. I am seriously thinking now that I would need to have some sort of addition to the bottom adding, whether it is bilge keels or something similar to stop the flat bottom settling on the mud....question is, how deep is the mud , I have just had a vision of 10ft high bilge keels on it lol.
  8. I am not quite sure if I am replying to people in the correct way so please forgive me if I am making a mess of this thread. Thank you Alan, your reply is insightful. It is definitely mud on the Penryn river at low tide, the thick oozy stuff, yuk. Your idea about having bilge keels added is definitely a thought but may be too costly. The reason we were thinking about doing this is because over the 3 years on the inland waterways we intend to put our own stamp as it were on the interior of the boat. Also a 40 ft canal boat is a lot more spacious than say a 40 ft motor cruiser or yacht to live on. Food for thought all of this..... I know Plymouth sound and the Tamar, it used to be a regular place we visited on our boat. I can well imagine the fun and games you have there lol.
  9. Thank you for your fast answer. I did suspect that it could happen, it was a bar of soap that stuck to the flat part of the the sink the other day that made me think this of all things. If it did happen where I was planning to eventually moor it on Penryn river, then the range of the tidal rise there would certainly be high enough to swamped a canal boat. Better to realise this could happen now in theory than to put it to the test!! ..... thanks again. It is looking that it is possible that it could happen, bit late though to get it released if it did get swamped, best not take the risk I think is the best answer haha.
  10. Hi, we are totally new to canal boats and are planning to buy our first very soon. We have had two smaller sea going boats so are not complete water novices. We plan to travel the inland waterways for 2 or 3 years and then have it lifted and transported back to Cornwall where we are from.....my question is.....due to the fact that a canal boat has a flat bottom, would the suction effect of it sitting on a tidal estuary mudflat at low tide cause it to "stick" to the mudflat on a rising tide, meaning there would be a potential for it to get swamped by the rising tide. Strange question I know but physics was never my strong point.
