  1. I’m with you on long overhangs. They are beautiful and hard to find on modern boats. I’m not a naval architect but have sailed boats with overhangs and the motion is beautiful. You know your stuff. Good luck and eagerly waiting to see how it turns out!

  2. I'm noticing the people with the strongest negative opinions, tempered by the fewest caveats, are operating on the least amount of information and the worst assumptions.

    Good you're considering failure modes!

    Not a degreed mech engineer, but I have a background in mechanical design and worked for a power boat manufacturer for a bit as a structural designer. I studied ISO 11225, the scantling regulations for fiberglass boats. I'm way too lazy to do this, but from what I know about glass work – which is mostly academic – and hearing your reasoning it seems reasonable and fun addition! Lots of production boats will have had their sterns reworked through their production life. Look at the Caliber 33 conversion to the Caliber 35 LRC. A slightly extended stern and a different water tank was really the only change, and those are well renown boats.

    I commented this in another video, but dude seriously, keep the mold! The extra space generally, a GOOD plan for a stern anchor, and the utility of the cutout to be used for either a windvane or (my idea) an outboard motor means this modification has appeal for a lot of people. There's piles of these Alberg 30s around (over 700 produced) and someone might want a new boat butt!

  3. It's your boat. If you want to turn it into a trimaran, more power to you. Ignore the armchair experts. As long as you share your wins and losses, we all benefit. Loving your videos.

  4. I am still trying to understand what you are doing. I even got a book ** so keep explaining your reasons in depth repeating things is helpful for us slow learners * In your video 3 ideas I am very focused on and still want more information 1)STERN ANCHOR, 2)SOLAR PANEL MOUNT, AND 3) THE BUMPER** It way too early for me to even think about judging the pros and cons CHEERS

    Do have any type of drawing or outline that you can post or put into the video ** you know a picture is worth a 1000's words

  5. Now that I see the profile drawing of boat and the addition it is clear what you’re trying to achieve. I think this makes perfect sense now. I love you sense of investment in the project and the commitment to the physics of the modifications. I hope your investments result in the outcomes you’re trying to achieve. I think you’re on the right track. Happy Hew Year!

  6. On insurance, I agree with you to a point. I’ve had only one insurance claim and am happy to say that they paid out without question. In my case it was a hit and run which holed the hull about 1.5 feet above the waterline (thank goodness!). That’s what I pay insurance for, while I rely on my own seamanship for everything else.

  7. I always assumed that… "It's your boat. You do good work so I have confidence that it will come out fine. What me (or anyone else) think is somewhat irrelevant."
    See if a college kid who knows CAD can help you on this project. Utilizing some technology may really pay off in the long run.
    Keep up the good work and wishing you and your family the best for 2024!
    LOVE the idea for a hard dodger!

  8. The problem with mixing carbon fiber and fiberglass in a tensile-loaded structure is they have very different elongation percentages for tensile-loadings. This means the carbon fiber portion of a laminate will take most of the load until the cf fails and shock loads the fiberglass portion. This means "adding some carbon fiber" to a fiberglass laminate does not make it stronger (higher breaking strength), it just makes it stiffer (less deflection under load) until the cf breaks. These videos by a composites-oriented engineer have a good, fairly concise explanation of the trade-offs: https://www.youtube.com/watch?v=KHXVf0SaJpA https://www.youtube.com/watch?v=j7bQYEt_qtU

  9. Probably a naive question here; why did you make a female. I thought the male mould would be enough, given that it would be used only once? I don't know much about making moulds. I'm just curious.

  10. What’s really important to recognise, is that pretty much every Sailboat can be made to Work, and in recent years, what I need to Work For me is KISS principles Tailored to what I need due to being Disabled and needing to keep Sailing Sailboats for as long as I possibly can. So Out Go Ketch Rigs, Cutter Rigs, and actually dangerous for me, Centre Cockpits, and classic Masts with Stack pack Mainsails and Hank on Foresails ( prior to disability, I just loved bouncing around on the Foredeck. My last Sailboat had almost everything I loved and was used to on all my previous Sailboats, and that Classic Mast and Closed Cockpit with a pita single wheel all turned out to be a nightmare for me to handle. So in Comes an Aft Cockpit with a Sugarscoop or bathing platform with secure docking and access to and from the tender and from there into the Cockpit, and a secure access to the Companionway An aft Cockpit is actually at least as secure as a Centre Cockpit with pad eyes and jacklines, just get used to clipping in at the Companionway, and essential for extending Sailcloth life while in the Tropics anyway- in Mast Furling Mainsail – But of Triradial Battenless construction, with three reefing points, but I’m hoping to get the third reef split into two Staysail sizes to test out. Foresail a furling Triradial Genoa, of lighter cloth, and three reefing points, so the Sail doesn’t get rapidly wrecked by furling it, like happens with rapid baggy pants cross cut Dacron- the shape of a jib or Genoa can be wrecked in literally a couple of hours just by furling the thing to reduce the size. With all lines led to the aft Cockpit, what Works for me when things turn nasty is – No Sailcloth for the wind to hit with its Leverage at the Bow or the Stern. If it is Heave to time then the Main gets furled to position Two reefs in Then either or Staysail position one, or the last bit of exposed cloth Staysail so all of the wind force is right at the Mast where I want it to maintain the Hove to. Progress in the desired direction can be achieved, or assisted by running the nicely overpowered inboard Diesel at fuel sipping low rpm with an efficient low rpm prop with a nice bit of torque driving it. tbh, I have never had a problem with Stern anchoring without special arrangements. I just drop the anchor over the side at the spot, then motor forward to where the Main Anchor is going to go. To be honest and Fair, this may not work out so well now that I’m disabled, but it is also an excuse to test another Anchor. 🙂 For Main Anchor, I continue to be delighted by the performance of an oversized Genuine Lewmar Delta, on the end of good quality all chain and a snubber tbh. I wish I had video of just how well mine performed after being hit by quite a number of Tornadoes, the first hit being so vicious, the anchor did what needed doing, which saved the boat, by being pushed out sideways. The boat was so far over, after hit from Starboard, that the top of the Mast VHF Antenna was under water on the Port side, and the Port side deck was awash, and about to flood the Cockpit. Than anchor alarm screaming, she popped straight upright Phew ! Then I just started the engine and flew the anchor between the boats behind me into the clear water behind them, and reset it there. The boat didn’t budge for the rest of the night despite multiple Tornado strikes. Talk about inspiring confidence. 👍 Best wishes and a Happy New Year To All. Bob.🏴󠁧󠁢󠁷󠁬󠁳󠁿🇬🇧🙂🌟🌟🌟❤️

  11. PS. I must confess that I really don’t like Wind Vanes for me, when things get iffy, their Reaction time tends to be way too slow. Also , the build quality of many seems to include far too much plastic. 4 x 250 watt good quality Mono crystalline high efficiency Solar panels weigh 4 x 15 kilo each for a total of 60 kilos main Housebank AGM batteries mounted just above bilge level at the Aft of the Cockpit, will easily Counterbalance the Rear Cockpit Mounting Arch , the Panels, and a Wind generator. The Render will be a Seago Hypalon 10 ft with air deck and keel, which will be rolled up in a Cockpit Locker, and the outboard will be a Tohatsu / Mercury 6 horsepower four stroke, that at wide open throttle, gives over 10 miles range per litre of fuel, so with two 12 litre Tanks, the minimum range is over 120 miles. at half throttle, over double that. That outboard is an easy fit in another locker or can go on a secure outboard mount on stern rails. 300 feet of high test chain should help with fore and aft balance Port and starboard Water Tanks with a Watermaker, should help sort Lateral balance. I’ll probably have to make some Tankage changes for Fuel and Water Capacity, and positioning for my tide me over Sailboat though tbh, which is the main reason for going with a bigger boat than I originally planned to get, so needed things have the room available to fit in. Best Wishes. Bob. 🤔👍🌟🌟🌟❤️

  12. Interesting discussion, very enjoyable. Wishing you every success with your projects but as an aside I continue to be extremely wary of battery powered propulsion devices in the Marine environment, as the energy density storage requirements fall way fort of what is needed with all present battery technology, and as yet, nothing suitable appears even visible on the horizon imho. Something totally different really needs to show up from totally outside the box, and very soon, as right now we are very long on unrealisable promises, and very short on the capacity to deliver. Best Wishes. Bob. 🤔

  13. Good video, great answers.

    To all those Karen’s, nagging Nancy’s and Chad’s. Go bother your neighbors or join an HOA board. Leave sailing to sailors. Sailors have crossed the oceans with cargo holds of smoldering burning coal.

  14. I’m not sure you owe the haters lengthy explanations – unless it helps you sort out your own thinking by verbalizing it. But I get the impression that your thinking is sound and that you’ve been through everything and have good reasons for everything…

  16. You don’t need to justify yourselves, spend whatever you like, do whatever you like! Happy you guys take the time to document it. If people have a negative opinion-you’re not making them watch your Chanel. Plenty of others!

  17. FYI, Highfield made a very light RIB. My dinghy only weighs 54# and I can pick it up myself. I have an 8hp 2 stroke engine that weighs 65#. But planing on replacing with electric. Also, an idea for limber holes might be using the type of fittings that sailing dinghy’s use. They create suction when moving quickly and hopefully when you are healed, you will have enough speed to suck the water out. When I had my Flying Dutchman I had two of them (we called them bilge rats) and you could close them when there wasn’t enough speed to suck the water out. Good luck with your project and all the best wishes for a Happy New Year to you and your family!

  18. A great explanation of what you are doing, even though none was ever needed. Given the ubiquity of windvanes on cruising sailboats you would think that somebody has already incorporated one in the design of the boat and maybe achieved a sort of symbiosis in design and efficiency. It looks like you are doing the next best thing. I look foward to watching as you share your progress.

  19. Whilst you are correct that lots of cruisers are piling absurd amounts of weight on their sterns in the form of dinghies, solar arrays, wind generators etc (and sometimes on the bow in the form of bowsprits), it is certainly not correct to say that this is OK – or that those who do it are 'quite happy'. Some are sick as dogs, whilst some are happy only because they are blissfully ignorant of the ways that they are compromising the design of their boats and some just never take their boats into challenging conditions. John Harries of Morgan's Cloud has been pointing out for years the disadvantages and dangers of these practices. I take your point that your proposed set up may be marginally less unseaworthy than many boats already on the water, but I am not convinced that this makes it a good idea, Especially as you DO take your boat into challenging conditions.

  20. I missed the live. This is hilarious. I totally understand the reasoning behind the modifications. I am sure that, aesthetically, the look will grow on me. 😜As for the critics… Suck Eggs, Pound Dirt and Build Your OWN! I am old enough to recall fiberglass and epoxy/resin hulls being raked over the coals and yet, here we are. I remember when sugar scoops first started appearing. That created some massive rifts and now it seems that one in three boats have a scoop (two scoops for every cat and Kellog). I still think foils should be classed separately and the Americas Cup should ban them, but that's just me. TOS over Next Gen any day and the freaking list goes on….
    You do U 🤩🤪
