What's new

I want to build an ultra light Sunfish. I have owned one in the past and will attest that at the current hull weight of 110 pounds they are strong

I dunno.

I've sanded "thick" fiberglass roving halfway-through, and had it collapse! Maybe cut lots of holes--instead? (In the deck, I mean...) :p

I want to build a hull that weighs 60 pounds purely for exhilarating speed. Obviously not one design.
Has anybody done this?
I doubt anyone has done this. I doubt you will get exhilarating speed unless you change the rig. Your best use of time would probably be to buy an existing Laser and make foils. You can buy Laser foils but they are pricey.

In my younger days, I wanted to build a lightweight cartoppable boat made of carbon fiber, I even took the time to make drawings of the boat on graph paper. She wound up resembling a fat rocket fish with a rig and slightly elevated bow, gunwales & transom... her hull was slightly rounded too, and I planned to use struts and braces to hold the mast step in place. I figured I would have a one-of-a-kind cartoppable boat, ultralight & fast, and I still believe to this day that she would be a successful design, exhilarating too, but the cost of the requisite carbon fiber alone was prohibitive, and she never came to fruition. Perhaps one day somebody will take up the torch and design such a cartopper, super light, fast, and easy to rig. A cross between fat rocket fish, scow, windsurfer and whatever else, designed specifically for the solo sailor who wanted to get out on the water with minimal hassle. :cool:

A friend of mine allied with the surf shop wanted to build a small fast cat using modified 'yak (or kayak) hulls, something he could assemble on the beach and launch directly into the surf. Of course, such a design would be more complicated, and it would also introduce stresses with which I'm not that familiar, as I've generally been a monohull sailor. But the idea was sound, only problem was we were in the same proverbial boat: young & broke, with more ideas than money, LOL. However, someone may read this post and think: "Ya know, that's not a bad idea!" And build such a craft... I for one would be happy to see someone do it, and if the design were successful, that hand could probably make some money marketing the craft. I don't mean NOW, with this idiotic Coronavirus scare, but later, when things return to normal. Shouldn't be too long, as freight is still strong---got tons & tons of it moving through this burg every day on the southern line. :D

My overall point is this: don't let anyone sway you from your dream... even if the boat only ever exists in your imagination, she can be a wonderful thing. The price of ultralight & strong materials will probably drop over time, carbon fiber was heller expensive back when I first thought of building my dream boat. But to this day, I think of how cool she would be: light enough for one hand to carry, fast enough to draw attention on the water. Remember when those fat little kite-surfing foil numbers appeared on the nautical scene? Those things were ridiculously fast, and every person nearby on the water or the waterfront was intrigued by 'em... I know I was, even though kite-surfing seems like too much work for me, LOL. I'm not lazy by any means, but I like my mechanical advantage, aye? A craft like mine wouldn't be as fast, but she would be far more comfortable, and a hand could drink beer while sailing her, a big plus in my book, LOL. I'm not sure kite-surfers can drink beer while under way, maybe there's somebody good enough to pull it off... :rolleyes:

Dunno if I still have those drawings I made, but if I find time to search for 'em and actually locate 'em, I'll snap some pics and post 'em up... thing is, today I'm on a mission to whack weeds, my least favorite activity in the yard, but it has to be done. Once I've been peppered by shrapnel, with boulders the size of Rhode Island glancing off my shades & face, all I'm gonna wanna do is drink beer, LOL. Boy, I hate that weed-whacking with a passion... to me, Hell is not the Fiery Pit, it's where Satan hands you the equipment and tells you to go whack tall weeds for the duration of your stay. In shorts & flip-flops, of course. Jeez, I already know I'm in for a beating today, but I'm gonna man up and face my fears... one o' these days, I'll wise up and use napalm & Agent Orange to do my yard work, that'll spare me the masochism & aggravation, LOL. Before this day is done, I'll look like Pacino in "SCARFACE"---that much is certain. At least there's plenty o' beer in my fridge, I even have 'handles' of rum & blue agave tequila standing by if I need 'em to ease the pain, BWAHAHAHAHAHAHA!!! Damn... :confused:


P.S. Maybe one o' these days I'll receive a Purple Heart, perhaps even a medal for valor on the battlefield... er, I mean in my yard, LOL. :cool:

Edit: Oh, yeah, the spools of weed-whacking line have to be the kind that tie themselves into a Gordian Knot on a regular basis, like Swiss clockwork... and where the heck is Alexander the Great when ya need him? LOL... meh, I have a razor-sharp Gerber Gator Serrator, guess it'll have to do for cutting the friggin' knot each time. :(

RS Aero hulls are only 66 pounds. The boats themselves are in the neighborhood of $10,000 though which is pretty prohibitive for many.
It would be cool to build your own boat!

A good friend of mine recently told me that he has been thinking of making his own sunfish from carbon fiber. His plan would be to make a clay mold of the upper and lower hull sections of his existing sunfish and use the mold to form the carbon fiber. His plan is to build the hull in workable sections and join them after they are cooked.
He mentioned that the price of carbon fiber has come down considerably from what it was in the past and he believes that the project is actually feasible, albeit with a significant investment in time and effort.
It would not be easy by any stretch but what he wants is to have a sunfish that he can easily lift to car-top when sailing solo.
If it ever comes to fruition, I will be sure to post pictures.

I hope he does build the boat... I can still remember the very first time my best friend handed me a carbon fiber surfboard, I was shocked to feel how light yet strong it was. I mean crazy light, that's what got me thinking about building a small boat entirely outta carbon fiber. Spars & all, ya know? Sail too, for that matter, though I would've settled for less at the time, including aluminum spars, LOL. All a function of the wallet, which was pretty slim at the time... good to hear that carbon fiber has dropped in price, I figured it would over time but lost track of the costs after bailing from Kalifornia. :confused:

Just came from a YouTube video of Comanche--"Superboat". :)

Huge expanses of carbon fiber, setting transatlantic record for monohulls, while keeping watch for icebergs. :eek: 40 knots achieved.

Takeaway line: "You want the best survival gear, so you don't turn into a human raisin".

A friend wrote of buying (another) light racing kayak. :rolleyes: Its weight is 26 pounds. :oops:

I asked, in jest, "Don't they make a light one"? :p

Answer: "Yeah, they make a 22-pounder, but it's $600 more in price". :confused:

Or surfboards... when carbon fiber boards first came out, they cost WAY MORE than most regular boards made of polyester resin & glass. The only regular boards which could compete in price were boards with really good graphics, air-brushed art, whatever. I'm sure carbon fiber has come down in price, same way big screen TVs have come down in price over the years... same principle, different product. Having said all that, some of the classic longboards in my friend's collection are now worth a $H!TLOAD of money... I kid ya not. Old Carl Ekstrom boards, old Takayama boards made by "The Donald" himself---er, Donald Takayama, not Trump---and other longboards shaped by early surfing legends who are now dead. I was shocked to learn that these boards are worth more than my car... and that was ten years ago, guess it's time for an automotive upgrade, LOL. :confused:

Meh, nobody will ever accuse me of trying to attract women by driving a flashy car... not with this 18-year-old Toyota Camry. Hey, I put some fresh brush scratches in the paint the other day at the Stronghold!!! Thankfully most of the 'scratches' disappeared when I took the pressure jet to the car, knocking off all the dust in the bargain. A few scratches still remain, perhaps they'll give me some 'street cred' for having a violent and vindictive ex-girlfriend, LOL. And who needs a fancy car anyway? [Cue the 'Sour Grapes' fable by Aesop, LOL] All flash, that brand-new Lamborghini or Ferrari, probably driven by some trust fund baby... spoon-fed maggot from the get-go, LOL. I'd take a VW Bus with a Baja rack any day of the week... or NOT. Always wanted one of them thar Lambos that goes over 200 m.p.h.---that or a Jaguar XJ220, also a sweet ride. But I wound up with an 18-year-old Toyota Camry, who would've THUNK it? :(

Any woman who loves me will have to love me for my SWEET DISPOSITION, BWAHAHAHAHAHAHA!!! And damned sure NOT my wallet... which is looking pretty slim, about as slim as a chicken's chances at a hobo picnic, LOL. Slim as a methed-up anorexic on the proverbial deathbed... slim as the Democratic Party's chances of unseating Trump in 2020... you start to get the picture, AYE? Aaaaah, this cold beer tastes pretty good, I was gonna mix up some margaritas but I have an interview tomorrow morning, so I'm sticking with beer... don't want anything to ruin my own chances of scoring this job, now that I'm first in line to be interviewed. It's a good job too, and no inmate crew pestering me to bring 'em drugs, LOL... as if that would ever happen. But that's how it is with an inmate crew, and once ya tell 'em no, they're uncooperative at best, surly & belligerent at worst... pfffft. I'm not the one wearing the orange clown suit, so f#% it. :rolleyes:

I should've pummeled that idiot who kept lighting up near multiple fuel sources, but then I'd be wearing an orange clown suit as well, no future in that... cost me a good job, that douche, along with the 'Kindergarten Politics' of the young fool in charge of the barn, dude clearly wanted his friend in my place now that all the hard work has been done (by me). I told the big boss on my way out, "THE PLACE WILL LOOK LIKE $H!T WITHIN A MONTH"---and it will, because those youngsters are lazy and slothful when it comes to keeping a shop clean. WTF, the mayor shook my hand while I was there, since he noticed the difference, I reckon he won't be so pleased next time he sees it, LOL. But that's no longer my problem... if I get this state job, I'll be taking a big ol' pay raise with all the same benefits, or even BETTER benefits, so to heck with the old job. Bunch of friggin' ingrates, as well as inmates... it'll be nice, NOT having to deal with an inmate crew again. :D

Oh, well, guess it's time for another cold one, I watched a good Western earlier and I'm about to watch another, I'm catching up to old Westerns since I bought a Roku Streaming Stick, this stick works better than any digital antenna would here in the wilds of southeastern Arizona, and I already have high-speed Internet in my home, courtesy of Cox outta Tucson. I like this streaming number, it offers a lot of options, and of course I'm behind the times when it comes to all this digital equipment. If I ever land on the Moon, it'll be after I'm shot out of a cannon while wearing a helmet & wingsuit, 10-4? Maybe some breathing apparatus, like Jacques Cousteau back in the day, LOL... I'm dating myself by even mentioning his name, but he & his family were once on the cutting edge of scuba diving. Inner Space travel, if you will... WTF, ol Jacques was an Inner Space pioneer, might as well give him some credit where credit is due, AYE? :cool:
