Looking forward to next week because it is a bit difficult to visualise your progress. What a big step forward getting that roof down well done. As for thanksgiving I think you deserve a nice little rest, enjoy.
She’s definitely taking shape, nice progress! Just an aside & I know its hard to stay on top of this stuff, but I’d highly suggest wearing a face mask or breathing protection when using the router or working with chemicals that off-gas. We want you guys nice and healthy when SVLynx gets out there on the water! 💪🏼👍
When you see me not wearing a mask while routing or sawing, it's because it is a short duration operation, and I just hold my breath (which I can do for 3 minutes, easily).
Lots of good progress this week. It will be very nice ot have the boat mostly dried in for the rainy season. I am curious how you will be getting the water to shed past the topsides below the side decks. I agree with you on the inadvisability of the overhanging toe kick on the stairs. That said, there is a physiological reason that the overhanging toe kick is a requirement of the standard building codes. Given the mechanics of the human walking motion, we need more room on the outside edge for the heal to land on when descending a stair. For the same reason we need more room on the inside edge for the toe to land when ascending a stair. This is accomplished by having the toe project 1.5" beyond the riser as was shown in the plans. As a precast concrete Engineer I design concrete stairs and the thin overhanging tread is a problem for a stair which is cast in one piece out of concrete. We accomplish this required 1.5" projection my casting the riser at an angle less than 90º so that it slopes up to meet the projecting toe. On your future stairs, you could do the same thing by leaning the riser out so that it meets up with the toe of the tread and then using some of your cutoff foam to make filler wedges at each end.
I understand what you are saying, but I've seen, and used, many a stair that has no over hang and they work just fine as long as the width of the steps are sufficient. I did some research and it showed that an overhang is needed if your step is less than 10" in width, ours are 10".
Love your work guys I’m thoroughly enjoying watching the progress every week please keep the video coming, just a question, I’m concerned about the strength of the vessel. Is it possible to run a test with a offcut of a glued panel
What is your concern? This is a Schoinning design, with over 400 boats built. They are known for their exceptionally strong boats. The composite panels are also used commonly to build boats. Nothing about the materials or construction methods are new to this boat.
@ fair call but I’ve been watching many boat builders and their using big strong timbers for keels and frames ect just seems a little under done with the material you’re using, but I guess when it’s all put together I’m sure the designers are a lot more intelligent than what I am
@@mannyvalenti475 It's not a matter of intelligence, I'm sure you are very smart. It's just research and development, with many iterations and testing. But, those boats you see with big strong timbers are not catamarans. They are displacement hull boats. Catamarans must be kept extremely light as their hulls are meant to glide over the surface more than plough through it. That's what makes them so fast. A displacement hull is limited by what's called hull speed. They create a bow wave with a trough that is as long the boat pushing through the water. The longer the length of the boat the longer the trough, and that effects the max speed as they can never plough through the bow wave they create. With a catamaran, they are kept light and have sharp bows. Due to this, the boat can cut through their small bow wave and exceed 'hull speed'. But none of that works if the boat is too heavy. That's why we use strong but light materials to build the boat.
It looks like finishing the pocket door gelcoat might be tough later at the helm ? Do they pre finish that area and the back side of step before the step install?
I think we talk about that in next week's video, but the short answer is, we're not gluing in the staircase until we get to the fairing, sanding, and painting phase, so that we can finish the inside of that pocket prior to the stairway being glued into place.
@@SailingSVLynx That is a good solution. I am sure you have seen the videos of MJ Sailing finishing off the same type of thin pockets for their sliding doors.
Why are you not wearing a mask when sanding or cutting. There is small bits of glass and carbon flying everywhere. You will not be fit enough to sail the boat when you are finished.
Great progress!
Thanks, we want this boat in the water!

Thanks, we'll see you next week!
Cracking on. Looks good 👍
Thanks! We'll keep working hard until she's done!

Great progress…. I’m a little confused with which bit is which (it’s all green and black plastic) could you do another quick walk around?
I'll try to do that.
Epoxy 🍻🤣
Lots of epoxy

Asked and answered in another comment. :)
Please use a mask, especially when grinding. Years ago I worked with fiberglass/epoxy without a mask and now it's catching up to me.
I have answered this numerous times, including a comment in this video, and I will again answer it in the next video. But thanks for your concern
