SC Hull Question?

Congratulations on doing some through research hiliner! Those numbers quoted in Mr. Moesly's patent are for the very first SeaCraft, the Moesly 21 (http://moeslyseacraft.com/SC21Brochure.aspx). On the 20' hull, I believe the deadrise on the inner panel is closer to about 18 degrees, although the numbers for the center and outer panels are about the same. I believe Big Shrimpin previously posted the exact numbers for the 20' hull on here some time ago. The 16 degree deadrise number quoted in the brochures is the average at the transom, measured from center of keel to the chine. There is another unique feature on the 19 & 20' hulls . . . if you sight along the chine from the front, you'll notice that there is a slight wedge shape to the outer panel (it slopes down at the back), which I suspect helps the boat get on plane at low speeds. As mentioned in the patent, a deep-V hull lifts further out of the water as speed increases, and I believe that outer panel is almost completely out of the water by the time you get up to about 40-45 mph! That outer panel wedge may be there in all the other hulls too, but I've never looked for it.

I believe the aeration created by the vertical steps (Click on the link in my signature to see a good photo of this) is the key to the soft ride and low drag of all the SeaCraft hulls. When I showed that photo to Mr. Moesly, he said that back in the early 60's, they spent HOURS at Lake X with a 21 trying to get a shot like that! A good buddy of mine that's a great photographer managed to get that one and a few others off Key Largo with Skip driving Carla's Bowrider, which made a great camera boat!

The vertical steps are much taller on the 21 than any of the subsequent models. I've ridden in the 18, 19 Bowrider, 20, 21, and 23' hulls, and IMHO the Moesly 21 is the best riding one of the bunch. Not surprising, since Mr. Moesly raced it in very rough conditions in the offshore powerboat races in the 1960's, totally dominating the outboard class, even beating some of the bigger inboards with 5X the power! If you look at the front view of Island Trader's 21 that he posted recently with the windshield mock-up, I think you'll get a feel for why it rides so well in big seas!

Haven't ridden in the Seafari 25, but I'd think it's ride is probably very close to the 21, since the hull lines up front are very similar. Naval architect and CSC member Big Fluke has tested a Seafari 25 extensively in big seas off Hawaii for his company, and he said it's "the most seakindly small boat we've ever tested!" They all ride great for their size, however, so do yourself a favor and find a CSC member near you and go for a ride! You will not be disappointed! Denny

Thanks Bushwacker, And that photo is a great shot. I'm jelous, haven'y riden in a Seacraft of any size "YET" Maybe this summer i know a guy that has a I/O 23 I think it's a Tsunami or Sceptre. If it out rides a Seabird, I hears they ride good as well. how does the 23 SC compare to a 233 Formula? Anyone compared these two? I might make it to FL. next winter, maybe catch a ride in one there too. After readind a post here on the 20 Sceptre of which i found one, I'm going to pass on it and wait for a 23 Seafari, I Hope. just affraid if i pass on the 20'er i'll never own one. Thanks for the info, good stuff. Are there any Moesly 21s around? Oh Island Trader has one? I'll check his out too.

I thought you were complaining that the Hiliner you have was too small? and you want to go to a 20fter? Thats going backwards in my opinion.

You can take a rid eon my 23 with the bracket this summer and let me know what you think

8 have been identified, 6 of which we know the location of: McGillicudy, Island Trader, and SkipperTee each have one. 3rdDay had "Black Jack" that he'd restored and traded to a guy in Texas for his 27, and I believe he still has the one he salvaged from the Keys; I believe Big Fluke bought the one that was for sale up near St. Augustine a few years ago and had it shipped to Hawaii. The other 2 were rigged for serious diving with big full-width folding swim platforms, and owned by Bob and Roy, a couple of engineers I worked with at Pratt & Whitney, but I've lost track of those boats: Bob's "Unohu" http://moeslyseacraft.com/Owners.aspx was a 2-tone brown model identical to Gillie's and belonged to a good friend of mine that retired about 10 years before I did. I lost track of him for a few years and he sold it in the meantime! I must have followed that boat for about 2000 miles all over the Bahamas and would have bought it in a heartbeat if I'd know it was for sale! He claims to have sold it to someone up in the Canaveral area, but we haven't located it. Roy's "Osage" was a 2-tone green version, with a Ford/Mercruiser outdrive that I went diving on once. Roy's dad was the original owner of my Seafari! Roy sold the Osage was to Frank Brown of Brown & Hauptner Marine who used to crew for Moesly on some of his race boats. Frank supposedly sold it to someone in the Keys that was using it for dive charters, but we haven't located it either. The one Brian salvaged from Keys was the same color as the Osage, and but I sent Roy some pictures of that one and he said it was not the Osage.

As Ryan posted on another thread, there are no 23 Seafaris, only the 20 and 25. There was a walk around cabin version of the 23 built for a few years but they are even scarcer than the 25 Seafari's. I believe Capt. Lloyd has one and another member out in Washington state has one. If you were interested in the 25 Seafari that DonV mentioned, send a PM to Carla (alias 65Bowrider)!

Hiliner222 - Do you have a Hiliner 222 now? If so that's a great boat. I wouldn't trade one of those for a 20 seacraft. Talk to Strick he might a spare 25 Seafari in CA if you can figure out how to get it east.

Yeah, the hiliner was free and i want a Seacraft. I'm going to pass on that 20 i found. It's an O/B and yes to small. Looking for a 23-25 SC. Have a weak spot for the good ole Classics. :-)

Wow the 21s are distinct, that one of Unohus' has quite a cuvature along the top side edge, Nice! I'll PM 65 bowrider, thanks. You know your SCs Great info, appreciate all the good info.

What are you going to do with the hiliner?

Restore/repower it to a useable boat.

[Bigshrimpin]

Are you looking for project seacraft too?

3rdday popped a mold off of the 21. Soon as I win the lottery, I'm gonna get him to build me one!
