Let's talk hulls - Striper Talk Striped Bass Fishing, Surfcasting, Boating

TheSpecialist · 08-06-2006, 09:26 PM

Was down Cape this past week,and my friend's next store neighbor had retired the 18' whaler after 20+ years of service. In her spot on the dock I noticed a new 18' Parker CC. After a little small talk I mentioned the new boat, and he told me he was not happy with it. He told me the boat rides hard in 2 footers and bangs. He has played with the trim, and can't seem to get a better ride.

What makes a diffrerence in how a hull rides? I thought Parkers were great riding hulls?

Also for you Seacraft guys how do 20' SF ride ? I am thinking of a project hull, but want something that won't pound.

likwid · 08-06-2006, 09:31 PM

whats he got for an outboard on it and how much fuel was he carrying that it pounded so bad?

i've ridden in a couple parkers and the only time they pounded was WOT.

but only the stupid and those who don't care about their wallets can afford to do that currently

Trim tabs will help.

The Parker is a nice hull. It doesn't have a lot of deadrise though. What you'll find out is; a boat that gives a soft ride generally isn't real stable at rest and vice versa. The Seacraft is a very nice ride with its variable deadrise. Though it's copied by several manufacturers now, it's somewhat unique. Great hull design. Very much sought after. haven't seen too many that weren't "projects". I know we have a few SC owners here on the site and hope they don't bash me for having said that. I would like one myself.

Parker's are a nock off of the old sea ox..a real work horse..not really made for zipping around in fast...they have a semi-v bottom..it's a very good stable work platform... .very little roll...but do pound in a quartering sea as only the bow has the v and flatten's out about mid-ships with a flat bottom in the stern. Also good for shallow water as it doesn't draw alot of water and get's up on plane faster because of the flat bottom.

20' seacraft..deep v....bring on the 4 footer's w/white caps...good for two when fishing....115 to 150 hp....turn your base ball cap backwards or lose it.

The more deadrise a hull has the smoother the ride but the down side is you need more HP to get on plane and get more kts than a flatter bottom hull.

MakoMike · 08-07-2006, 08:42 AM

See the discussion under the topic of deadrise. I believe the Parkers are a semi V hull which will pound when pushed hard enough into a head sea.

keeperreaper · 08-07-2006, 08:49 AM

I agree totally with capesams. The potter built seacrafts INHO might be the best designed small hull ever and they built them heavy not like the newer seacrafts. MV hulls will pound versus a DV hull which slices the water but rocks more.

Mr. Sandman · 08-07-2006, 09:33 AM

What is the unique aspect of the seacraft hull design is that instead of spray strips to separate the flow at speed, the design uses a series of steps in the hull wedge. Most deep V's today have a chine like strip to separate and deflect the flow and this causes a positve presure region under the strip, and inturn tends to reduces the deadrise effectiveness. You need to separate the flow to reduce the wetted area and have a dry ride somehow and what seacraft did was have a inward longitudal step in the hull to obtain separation but without reducing the effectiveness of the V by putting a large spray strip or chine. The result was a very soft riding hull for its size. (Without a lines drawing of common V and a seacraft this is the best I can do to explain why it is better) Look at a seacaft bow on and any other boat, the seacraft hull looks inside out. (sortof)

As for the "old" vs the "new" hulls I think there is a lot of personal issues dealing with this as the lines of the hull and the design principles are the same. I prefer the new hulls as 1) they have no wood in them and 2) they are lighter 3) the resins today are better in seawater. Back in the 70's they used wood for various structual elements and this basically was a bad idea and most of them eventually rotted. I will take a 100% glass boat and if I want a "heaver" boat I will carry more fuel or payload. The weight adds to a softer ride in any boat. But you pay to carry weight around.

I think the cult following of the older boats has evolved because that you can pick them up pretty cheap, fix them up (with a lot of sweat equity) and have a good hull in the end. I think it is great to see the older boats around and I know the owners are proud of the design and their hard work.

Soundings or some other mag I get did a review a while back of the 10 best hull designs ever and seacraft was among them. ***For the size*** this hullform gives you an impressive ride. (its a little boat though, keep that in mind)

capesams · 08-07-2006, 11:07 AM

older hulls you can:

leave on a trailer for years without the fear of the rollers pushing the bottom in.

you can drill just about anywhere and only need washers to back up the bolt...not alum. plating or starboard or wood.

the sides don't flex like tin and won't spider crack.

punch a hole in anywhere and you have some meat that surrounds that hole to work with/repair.

they can take a pounding and keep on going.

I've seen half the bottom taken off of an older 23 seacraft by a floating log and it came home from offshore safe and sound[thick hull] wouldn't want to try that with a new boat / thin new an approved resin's.

keeperreaper · 08-07-2006, 11:53 AM

Amen.

When your miles offshore I like to know I'm riding a seaworthy safe overbuilt boat for peace of mind.

That's basically true. If someone gets a Potter hull they should assume that they will need to redo the transom and floor. However they are the only places that there is wood. The stringers are boxed fiberglass.

The newer boats are better in overall design in many ways as you've pointed out. The big problem is inconsistent/poor quality. The worse problem is stringers coming loose from the hull. That just doesn't seem to happen with the Potter hulls.

i just got my boat but am already thinking of my upgrade... this boat is a good base line and now i know what i want for my next boat.

these are two totally differnt setups but i like both..

what do you guys thing of a 21ft sea swirl walk around
or a 22ft eastern lobsterman. both seem to be pretty good bang for your buck and you could pick up a used one for under 30 if you look hard enough. today... those would be the two id choose from, different yes, but i like both styles...today

tomorrow?? well who knows.

Still fish my "stock" 71 Seacraft Seafari hard several days a week. Passed down from my dad to me and I figure it will go to my son after I'm done with it! Look me up in 35 years and let me know how that brand "X" is holding out.

i am really looking forward to your progress pictures, Krispy

Krispy · 08-18-2006, 03:56 PM

I just read somewhere that the Hi-liners (Ray Hunt design) were very closely modeled after the 20' Bertram, minus 1 chine. If thats the case they should run pretty nice

Got some fun air tools delivered last night from Homiers. A little body saw (reciprocating) and 4" cutting wheel and picking up a cheapo angle grinder over the w/e. WEEEEE!!
Pics 2nite

24 grit disc..old glass is tough.

looking good. keep us updated. I am really excited to see that thing opened up...

Opened up as in Wide Open Throttle?

Or Opened up as in you can visually inspect the stringers from Google Earth?

Keep up the good work Krispy! What is your timeline for fishing the boat?

Krispy · 08-20-2006, 11:36 AM

Thanks guys, Ill update some pics tonite. I removed the entire engine box, I can see possibly re-using part of it to make a splashwell. The floor was surprisingly solid throughout.
I thought initially 1 year, August of 2007. But things are moving quicker than expected, so I hope to have the hull complete by spring, $$ depending.

Krispy · 08-20-2006, 11:38 AM

Ill start a new thread so I can update it as it progresses
