Take 2 Sunfish—Make Catamaran?

I didn't realize you were located in New Hampshire, nor that Massabesic Lake had a speed :oops: limit.

Very nice job! Are you considering a "boom camera"?

I have a "Matrix-18" catamaran with a beam that is 10-feet wide overall. I towed it "flat" all over Florida, before realizing that 8-feet was the limit on towing loads! :confused:

The Prindle rudders had been stolen at the time I'd bought it, and was only able to locate one Prindle rudder when I put it in the water. That was thirty years ago, so just one Prindle rudder has been "enough rudder"—even while flying a hull.

On your "narrow" (to me) Sunfishamaran, do you really need all that rudder surface?

The "Matrix-18" catamaran came with a huge genoa jib, which makes for a scary-fast ride—much faster than my Hobie-18 and Tornado-20! What would happen if you went for a monster jib?

Those 10-MPH winds suggest you haven't been able to "fly a hull" yet. (That's a question ;)).

Holy Guacamole, I'm heading up to New Hampshire to take a look at this beast!!! Now all I have to do if figure out where Massabesic lake is...

The design goal is to sail it as flat as possible and keep planing like a wide board windsurfer. I want to have as presise and controlable a helm as possible. I did accidentlly "fly a hull" while attempting to put some shape in the sail by sitting on the leeward rail. A slight gust(??) quickly hiked the boat alarmingly. Not only is there a lot of sail, but also a lot of weight aloft. Lesson learned: Be Careful! I am working on a righting system. Maybe one person on each daggerboard?

When sudden gusts hit my catamaran, I immediately pointed upwind. Now the answer is to slacken your sheets and point downwind. :confused: We have a lot of gusty winds on NH's Lake Winnipesaukee...I'm sticking with what I know. ;)

Until you get a righting system perfected, try raising the leeward daggerboard—a lot. A gust will put the major load on the leeward hull which will allow some slip. The momentum of the weight aloft will be lessened, which will likewise relieve the pressure to overturn.

Stiletto catamarans put one daggerboard between the two hulls—perhaps for that very reason. (They're big, and I wouldn't want to have to right one!) :eek:

Wish I had known you we're taking that out, I would have come over to watch (about a 20 min. drive from my house).
Bet the Manchester Water Works folks are scratching their heads on this one. Sunfish aren't legal on Massabesic, but it's not really a Sunfish, or is it?

Congrats on putting this together professionally and with great forethought. I am really impressed you were able to pull this off, so a sincere and hearty congrats!!

You may need either one crew or a trapeze, or a few simple mods. A Trac 14 had a beam of 7 1/2 feet. Although Sunfish each have a beam of 4 feet 1 inch, the effective beam of your boat is less as the hulls are canted - plus the water line is curved and unlike the Trac your 8 feet 2 inches of beam is only at the widest point, where the Trac was 7.5 feet wide for its entire length. Crew will add a lot of weight though - the Sunfishamaran is already about 100 lbs heavier than the Trac, which had a hull weight of 195. I think fiddling with the boards (do they really need to be full Sunfish length - perhaps shorter but foil shaped would help?) and perhaps making this just a beam/broad reaching machine instead of looking to sail upwind would let you see the max performance and the planing on one hull. I would love to see this on a broad reach in 20 knots!

Officially the story is that it is a Sunfishamaran and I'm stickin' to it. =-) alcort-padco-sunfish2.jpg

I saw that 35MPH sign and thought that was a little fast for a boat ramp!
People in NH must be in a seriously big hurry to get their boats in!

That Sunfishamaran is impressive. I didn't think it would turn, but apparently I was wrong and it is a high performance double dinghy. Although I can't stop thinking that it looks sort of like the result of a high speed, completely inelastic, Sunfish racing accident. (Except we don't live in a cartoon. But it would still be fun to tell children that's how it was made. ...children and everyone else.)

Nice work Pad. Time to look for your youtube channel & video of the Sunfishamaran.

It'd be legal on Lake Winnipesaukee. ;)

:) Hey, NH1-PAD...!

The tenants at my Lake Winnipesaukee (NH) cottage are leaving tomorrow—there's no tenants arriving until Labor Day weekend. It'll be empty.

I'd like to see this boat in action—so why not launch the Sunfishamaran just once up here, and enjoy it for the Saturday and Sunday of next weekend at no cost? Extend your lakefront stay—or the stay of any Sunfishamaran admirers bringing their own Sunfish—at only $100 a day. (Up here, that's a bargain in lakefront rents!)

Sorry. Busy both days. =-(

:confused: But there is 12-feet between 50-foot docks—perfect dockage for a Sunfishamaran! :(

Well, the $ offer is still open to enthusiasts until September 1st, when a new tenant arrives. There are four twin beds, a bunk bed, and a fold-0ut queen (one bathroom!)—but you must bring a Sunfish!

(Not too prepared for racing, however). ;)

A serious-sailor-buddy—just retired and just three hours away—is waiting to race my spare Sunfish. A gal in town wants a Sunfish racing get-together for her incredibly immaculate Sunfish.

Who may I pencil in? :)

Sounds like a good deal to me, however, I'll be at Bow Lake the next two Sundays, and I would not be able to bring a Sunfish (I don't have one:)).
I could come up for a day during the week (it's about an hour or so from my house) and bring my Phantom.

A Phantom, huh? :confused: Doesn't a Phantom have a better Portsmouth rating? :eek:

...Just kidding...;)

My September 1st tenant has a Phantom—at least two Snarks, and a Sunfish or two—but I don't want to "step" on his family's Labor Day vacation.

I'll run a mid-week event through "channels" and see what can be put together. :)

You're welcome to bring your Phantom. I've checked, and the Portsmouth Rating is better for Sunfish. :p (But that may be a "numbers" thing :rolleyes: ).

:( In our already too-short season, I've procrastinated a week already—but this morning, put out a possible mid-week scheduling:

August 28, 29?

September 5, 6, 7th?

September 11th (Patriot's Day) the 12th, and/or 13th?

Except for the Labor Day weekend, other weekends are "good" through the month of September. Surely, the Sunfishamaran can stretch its legs here on Lake Winnipesaukee!

Shameless plug follows :cool:: Overnights in the little cottage are still the same per night and—except for my regular tenants' dates—that offer extends through next season!

So that's four of us. :) September 5th was everybody-else's choice! :D

One will be here a day early, and stay in Wolfeboro. The other (and me) already lives here.

Off-street parking near the ramp is available—I'll check for what's available—exactly. Pick me up, and I can drive your car/trailer to within 200' of the sailing activities. Your sail from the launch ramp is through some variable wind directions, and is about 1½ miles. A powerboat-tow is available.

The rest of the details should be conducted by PM or telephone, but others who want to participate are welcome to
join us.
