2000 20? Seacraft

Hey guys, I?ve been stalking this forum for years,anyway now I?m finally able to potentially purchase my own Seacraft. I?m a boat rigger by trade, and I?ve repowered 2 20? Potter hulls with Suzuki?s. Anyway, the tracker site doesn?t have any Seacraft links I can find and you guys are super knowledgeable. I?m considering a 2000 Seacraft 20? for a potential bracket candidate also thinking about moving the console 8? forward. End result would hopefully be a beautiful Seacraft with a DF 200 that still self bails. Of course I would use a flotation bracket, but any advice would be much appreciated.

I still learning how to put in pictures

Sorry, meant move console 8? forward.

welcome..another Tracker member

CG of heavy engines on brackets

Suggest you see my post and sticky. think of 9-24-16, of estimating CG shift with heavy engines with brackets. I provided an example you could plug your numbers into and you can simulate results with temporary loads like water filled coolers or lead weights. I realize most will fly by the seat of their pants or are scared of the math to try it, but the physics should prevail. Try it. What do you have to loose? Best wishes!

Terry - I made your post a sticky a few years ago in the repairs section. I'm not putting my head in the sand and disputing math/physics, but I think the additional stern weight and LCG shift (of 1ft) is significant and very noticeable. Sadly I can only offer my own anecdotal evidence :p (which doesn't mean squat) from running the 20 seafari w/ bracket and 20ma with transom mount outboards. Adding 100lb kicker to the transom on the 20MA was noticeable. When the 20 seafari's inspection plate on the bracket leaked and the tub filled with water that was also very noticeable. The extra weight on the transom and changes in the running angle at lower speed could be felt (or were reliably imagined. :).

The resulting CG shift makes a big difference in the boat's low speed planing performance, and ride when it gets rough! Fortunately, the Seafari's big cabin makes it easy to put a lot of gear up front when you're making a long trip. I even installed pad eyes on the bulkheads so I could keep it all tied down in rough seas!

Do you have trim tabs on your boat? They will help compensate for load/CG shifts. A 4B prop will also give you more stern lift as will an SE Sport hydrofoil on the AV plate.

I do appreciate your post that shows how to calculate (and compensate) for the LCG shift. Maybe someday I'll write a matlab program with some strategically placed sensors and sandbags to add some more "science" to this discussion.

p.s. - I ran a different prop for part of the fishing season. Thank you!!

Did a total restoration to a 1974 20 Master Angler two years ago. Used a Hermco bracket and a 150 G2, should be able to answer a lot of your questions.

Very nice! What year did they introduce the Master Angler?
