I would not be looking forward to all the fiberglass work you guys are going to be doing, but once finished your going to have a fantastic boat. I hope I am around to see the finished product. Good Luck.
Thanks, Peter, we will do our best. I am sure we will make mistakes, but with plenty of feedback and suggestions from our Patrons and viewers, we can fix anything we mess up.
The problem with lightning strike mitigation is that I have not yet seen any proof that it works. We will continue to do research into it and if there is any indication that some system actually has real benfits, then we would consider adding it. Our best way of avoiding lightning strikes it to sail around storm cells as much as possible, with a fast boat. That's another reason we wanted a performance cat of good waterlength.
I have to give you credit. You not only spent 10 minutes replying to my earlier comment, but I got a subsequent mention in another vid. I have researched cats extensively, and we have previously owned a Catana 42 2013 (second owner of a very pimped ride), and now own a Balance 451 (also second owner). Everything takes twice as long as you think it will, and cost more than you have planned. The important thing is that you enjoy the journey. Based on previous experience, I would like to suggest that you keep the crossbeam polished aluminium. Painted alloy is challenging, and better to keep it simple. One of the features on the Catana was sealed waterproof bulkheads, which add to safety if you hit anything submerged. A final thought is considering the weight of an 8 person life raft (a 6 person one we had weighed 40kg, and ideally are placed where they can be deployed readily. We have a fully enclosed cockpit with an elevated helmstation on the Balance, and we love it. Keep up the good work, but man, I would hate to be you. (Resale value on boats is always higher if you are building through a recognised boat yard). FYI We came very close to buying a Schionning, but it was too wide to fit in our berth (we live in Tauranga New Zealand).
A lot yo unpack here... but here goes. The crossbeam is made by us, with carbon fiber over strip planking. There are various watertight bulkheads. Our life raft will be mounted on the bow, as that is the least likely place for a fire, which is the main reason it might ever be needed on a well designed catamaran. We love being us. And we don't give a rat's ass about resale value, just that we have a great cat to sail. Thanks for posting.
Very interesting project. Looks at least like you have the proper workshop, etc and a lot of motivation for this project. I'm very excited to follow the progress. Followed a similar project (Arrow 1360) not very far from where I live. Many people working on the project, but only part time. Took them about 4y to finish it. There is one feature, which in my opinion is overrated: the capability to beach a catamaran (without keels), especially in regions with small tidal range. The maneuver is more demanding than regular anchoring, it destroys a significant part of the bottom paint and you do it once every few years, because often you don't have the conditions to do it. Imo not worth the costs and effort.
I understand your reasoning on the beaching, but we aren't just sailing the milk run in our cat. We plan to visit parts of the world where we will have little choice. In northern Europe, we will be in massive tidal change areas for several years. And, like in Northern Europe, while visiting the Kimberley islands of Australia, the tidal changes are 30' (10m) at times. In those locations, the boat may need to be beached quite often (and we will just have to deal with the bottom paint repairs). However, knowing that we will have to beach the boat during those years, we need to make sure the boat is capable of beaching without damage (other than to bottom paint). Obviously, we will try not to beach it whenever possible, but the boat still has to be capable of beaching.
I disagree that beaching keels are not worth it. As Phillip has said, in remote cruising it can be very worthwhile. We have very low (200mm deep) but long beaching keels made very tough that we can careen on less than optimal bottoms if necessary. When I looked at the point loading ( think hidden rock or coral under the sand) force on hulls without the mini keels, it was a bit scary especially if there was any wave action on the re-floating period. They also have advantages for down wave tracking, and do not affect tacking performance, if they are designed right. I think they are all upside benefits, IMO.
@@robthompson7174 On your point, Rob, about point loading without mini keels, that is the whole reason we spent a whole lot of extra money to purchase basalt fiber to put over our entire hull bottoms (three layers). We wanted to increase the strength of the hulls. I very smart person I know who works on boats suggested basalt. When I looked into it, I found a video where somoene shot a hull made from fiberglass and one made from basalt. The bullet went right through the fiberglass and bounced off the basalt hull. So, we are adding basalt since we must careen on occasion on our hulls, which do not have mini keels. It may also help in case we hit something in the water. :)
Thanks for comment on the basalt fiber cloth. I did not know it had toughness properties that good. There are 2 issues to consider, one is hull penetration, the other is delamination. We tried and tested Innegra cloth, it has certified ballistic properties and our sample panel was truly impenetrable. BUT, it does not wet out at all with the resin and we had massive delamination failure of the infused hull panels. The outside Innegra layer had to be pulled off & it just peeled off with no adhesion to the main laminate. A real PITA. I test everything, I hate surprises! And thank goodness I did. You would be surprised at what works and what doesn’t sometimes.
The workbench itself won't cause much weight issue. If the tools do, we can always move them to a more central location and just take the ones we need to the workbench when we do a job. We have always considered balancing the boat a top priority.
Good luck with the amazing project. you have no doubt spent 100's of hours working on your design so it is unlikely that someone who watched a few hours could make any constructive comments but I am going to try. It could be that I have missed it or it has simply not been mentioned but you seem to be missing a fish cleaning station in your rear cockpit? Given your professed lifestyle I assume that fishing or spear fishing will be a high priority.
You're right, we haven't gone over our fish cleaning station, but it is in the design. I will show you in an upcoming video, but thanks for trying to help!
As for the time it takes to make the boat, only time will tell. But when it comes to the cost, there we are pretty sure we will not go over our budget. The thing is, building a kit is not like buildig a boat from a pile of lumber. Everything to finish the shell comes in the kit, so that is a fixed cost we have already paid. Then, there are all the systems you need to put into that shell, and we have purchased most of them already: sails, rigging, mast, boom, engine, hybrid system, tools, electrical, solar, refrigeration, tender, outboards, and more. All paid for and in storage right now. We have even prepaid the rental for the build site. There are very few things left to purchase. As for consumables, like sand paper, we have set aside a rediculous amount of money for those things. There are a few smaller things we still need to purchase, but even if we are way off on the cost for those, they are a small portion of the total expenditure. At this point, we are underbudget by $26,000, which leaves a lot of room for those small things to have extra cost. So, we are very confidant that we will stay right on budget at this point since it isn't an estimate anymore, we pretty much already own it all. We bought everything early becuase the dollar was strong and we didn't want to get bitten by delays due to supply chain issues. That will also help us keep on time in the build, but like I said, as for the time it takes, we will have to see. Unlike many DIY builders, we don't have to balance work and boat. Many people only work evenings and weekends. We are all full time on the building of the boat. Look at MJ Sailing's channel, they are just a couple, one guy and one girl, and they are putting a kit together in about two years. We have four full time people, three guys and a girl, plus a lot more part time help (around 12 people). So, based on MJ Sailing, we think we can build our slightly larger kit in the same time they take to build theirs, or technically, faster. We'll soon find out since the build starts by February, 2023.
@@SailingSVLynx With a lot of people you may get it done. From personal experience I am amazed how long it takes to build the interior fitout. the hulls are easy but the fairing is a killer. Anyway good luck....
As a Salina owner I can definitely see the Salina influence. The Salina is a great design but very poorly executed. To say the construction was shoddy is giving FP far more credit than they deserve. My wife and I have said we would love nothing more than a well built and fast Salina. It seems you're getting exactly that.
We loved certain aspects of the Salina 48, but a used one turned out not to be in the cards. A am sorry to hear that the workmanship was not as good as you hoped. The good news is, we can only blame ourselves if something isn't good about S/V Lynx.
For comparison purposes I'd be interested to hear what your hardtop weight is? Per square meter/foot if possible. Ours turned out to be 505 kg for 39 square meters which is 12.8 kg/m2. And that's without the solar panels. More than I expected and hoped for, so have you asked for that info, and whether it is a target area to save weight with use of more carbon? I'd love to know if ours was over built by comparing to yours.
would you evaluate that I am thinking a trimaran that whole roof covered with semi flexible electric panels and works only with electric motors and lityum ion batteries. 30kwh. size 7m*5m equals 35 square meter. produce 4kwh electric. 3 electric motors. 3 *9 hp equivalent. cruising at about 8 knot speed. 1000 kg body.
That's not enough for us to make a real evaluation. I can only tell you that we looked into pure electric with lots of solar and found that, in the end, the range was just not good enough for our needs. We will be making a video about how and why we went with the propulsion system we choose. Perhaps that will help.
@@metinmet7637 I will answer, but anything I say is pure guesswork without a lot more information about your boat. You say you will have three 9 hp electric motors. Each is around 6.7 kw then. You can't run electric motors at full power for long stretches, so if you figure you are going at half power, that's about 10 kw. You only get about 80% of lithium batteries, so figure 24 kWh, which means you may motor 2.5 hours using 10 kw (approximately). If that pushes your boat at 8 knots, that's 20 nautical mile range.
@@SailingSVLynx thanks, in sunny day in 3 hours 12kw sun electric will be produced, so in total , the range become approximately 20 mile, is calculation true, for small daily rage it may be feasable, I try to design my future electric boat, of course this figures are approximate numbers, thanks for your valuable comments and videos,
