The Double Eagle, launched 1967 as the first powered catamaran licensed by the USCG to carry passengers. Builder: Clark Mills, Clearwater Bay Marine Ways for the Old Man and Double Eagle Enterprises. The Number II and III are still in operation out of Clearwater. The DE II was also designed by Clark.

Back in the day...when water was not crowded and when Malibu Outriggers began to rake the surf in CA...without masks, doncha know!
 
Northern 11 1987. Just putting it back together now. Has it made the past historical multihull designs?

For the past 2 days, I've been reading back thru this long and interesting subject thread. Then this morning I came to the latter postings, and found this one of mine. I was rather surprised that not many (any?) folks bothered to reply to it??

I'd still be interested in issuing that le-Mans 'Sailing Challenge'

Ppalu sailing trip



We finally got out of the inlet at St Augustine on Sat morning. Turned south towards Daytona and made it on one tack.

We put up her full sail ketch rig and sailed very relaxed at 8-11 knots on a close reach. The winds started somewhere around 10-15 knots out of the east and increased to 17-22 knots by the afternoon. (we did not have wind measurement instruments, so these are estimates of mine and the skipper/owner Randy West.
Our speeds were derived via hand held GPS.

We experience a considerable ocean swell on our beam as a result of the wind having blown all night and day the day before. The swell got bigger as we approached the inlet at Ponce. We ended up surfing in a sizable swell. In fact Randy West who grew up in this area commented it was one of the largest he had ever tried to navigate thru.

Its been awhile since I've been out on a big multihull (Ppalu is 75 feet). Some of my thoughts on such designs for aging sailors have been fully reinforced:

1) The ketch rig is a godsend. There were 3 of us on the boat,...all over 55 years of age. Handling that mainsail was a chore, and I could just imagine trying to do it any shorter-handed, and in much heavier winds. Then I thought about this vessel being rigged as a sloop....WOW just that much more difficult. Even as a ketch the main mast is 63 foot tall. As a sloop it might have been 80 plus.

The mainsail was a 'stack pack' arrangement with some laze jacks. When dropping it prior to surfing in the inlet it did not what to just drop into the stack pack,...but rather this rather big heavy sail wanted to flake out over the boom and impede our view forward to help negotiate the waves we were going to surf in. It would not have been a one-person job!

Even the non-overlapping jib was a heavy sail, even while constructed of modern materials.

The mizzen was a great sail to maintain balance. We barely had to touch the wheel to keep her on course, while sailing thru a good size ocean swell. (we did not expend a lot of extra energy on tweaking the sails for max drive).

Then we had to put those sails away in the bags and covers once we were at dock. That took at least another hour, with 2 people.

It all went to reinforce my beliefs in my all-furling single-masted ketch sail plan.

Overlapping Genoa and all-furling rig

2) I would prefer a dual helm station to the single one on Ppalu. It would allow one to read the sails more easily, and to get out of the shade of the mainsail at times. It was a cable system with a very large diameter wheel which gave plenty of steering power, and feedback (unlike hydraulic systems).

3) The single big outboard engine on a lowerable skid under the bridgedeck is a very adequate propulsion option for a sailboat auxiliary. Ppalu's needs to be hooked up so as to steer with the helm when docking and maneuvering under power. And I would likely modify the pivoting skid some what. What night even be more applicable without getting too fancy, would be to be able to separate the 'powerhead portion' of the engine from the drive leg. It would certainly be nice to just have a simple retractable drive leg/prop arrangement, with the powerhead portion up in a accessible 'engine box' on the wing deck.

Ppalu's outboard was adequately forward enough to not jump out of the water that often even in the considerable swells we were in. But it would have been even better had we not had that big (150hp) outboard hanging down there, but rather just a silent chain driven prop drive leg.

4) There is a lot to be said for keeping the systems simple, even on a large vessel. Her refrig and LED lighting, and cooling fans, and navigation computer were all powered by two solar panels
 
Victor Tchetchet's 20' Trimaran, magazine article plans from the 1930s preview, need to sign up for unlimited downloads, of which it says it's free for one month.

AYRS - Amateur Yacht Research Society (A.Y.R.S.) Publication № 10 - December 1957 (PDF of 32 pages)

There's | 8 × ‘‘Tchetchet’’ | 12 × ‘‘Trimaran’’ | 1 × ‘‘T26’’ | 1 × ‘‘T 26’’ | 1 × ‘‘T-26’’ | 5 × ‘‘Egg Nog’’ | 4 × ‘‘Flamingo’’ | 2 × (Bud) ‘‘Dealy’’ | mentioned in this AYRS publication, which gives a lot of info when the document is searched for these keywords, didn't read it fully yet, so there might be more.

From a first quick glance through it: Victor Tchetchet's 26' T26 ± 1940s, 26' Egg Nog ± 1950s (?), both Tchetchet trimarans being built and raced in the US, among others in the 1957 Bayside Yacht Club regatta against Bud Dealy's in the summer of 1957 launched 26' trimaran Flamingo.

Didn't see Egg Nog II there, so maybe that one was designed and built a bit later.

Victor* moved from Kiev in the Ukraine to New York in the US in the early 1920s, maybe eggnog (possibly with rum ?) was one of his favorite drinks, which might have made him name some of his designs after it . . :)

His mast aft rig was an inspiration to me. I think I found some photos of it in one of the AYRS publications. I posted those photos over here, but have never seen them mentioned/posted in any other internet site. Turns out both he and I are mentioned on this page of the indexed site,

Here are those photos,... Aftmast rigs??? https://www.boatdesign.net/threads/aftmast-rigs.623/page-49#post-742264
