Fletch's Hydra Sport 2100 CC

[Fletch170]

OK, found a place local (an hour away), that sells Penske board, so that is what I'm using for the transom/ stringers/ rear deck.

I've done a lot of research on the intergoogles. and it seems there is no one way to do this. I'll create a template for the penske board, cut them out and glue the 2 3/4 pieces together. From there, I have a few questions:

1. Once i have the inside skin of the transom all cleaned up and ready for the new core, I see some people laying another sheet of 1708 before using cabosil putty to bond the new core to the skin (will use bolts through the transom holding the core to the skin). Is adding another layer of glass necessary? This thing already has a ton of glass.

2. After gaps are filled and a filet is created around the corners of the new core, what is the best Biaxal cloth to use to skin the inside? 1808? 1708? Roven woven for thickness?

Any good tricks? Suggestions?

Started tearing the transom out this weekend. Lots of fun. Despite it being completely shot, it sure did put up a fight coming out.

The port stringer is really bad, and I'll need to go forward further. There are those boxes in the way. Question:

They did not support the deck, so I'm assuming they are structual? However, they have very little glass on them, and have 1/2 inch plywood cooring. They are filled with foam.....so I'm wondering of they are simply for flotation. If this is the case, I'm inclined to remove them.

Suggestions??? Maybe just replace them with a coosa "cross member"?

[RickK]

I have no idea what they would be for unless there is lead weight in them for getting the CG right :017:

[gran398]

Exactly as you surmise, sealed flotation chambers. I'd ditch 'em. Gives you a lot more room for bilge/bait/washdown pumps, freshwater etc. And heck, you may ditch significant weight if they're waterlogged.

Plus those bilges were small to start with.

[Fletch170]

Figured as much.

The 2400, which this was built from, had grid stringer system, like the AS. (glass filled with foam). However, mine is wood. Why the hell wouldnt they just shorten up the stringer when it comes out of the mold and glass it in? I guess it may have interfered with the 2100 deck layout.

From what little information I can find, it looks like the later 2100's did have a glass stringer system. Anyhow, the boxes are coming out, and oversized stringers will be built into non rotted stringer structure.

GOnna drop about $600 bills on Penske board....but hey, it will last a lifetime.

[gran398]

The final years 2100 morphed to the 2200 which isn't nearly the ride you have.

Yours looks exactly like my old boat. Massive boxes which I never figured out given the two little twist offs for bilge access. Back then (I was 28)  figured those big boxes were the stringers, based upon what I could see.

You hit the nail on the head, bet they had an insert in the 2400 mold where they could produce either a 24 or 21. Then fill in the blanks.

You're idea with the coosa bulkheads is how I'd proceed. Looking forward to seeing how heavy those boxes are when you pull 'em. Get the weight out of the arse end....good news :;D:

[Fletch170]

Who knows with OMC, but after some inspection, I don't believe the 21 is just a shortened 24. Take a look on the web, the 24 looks to have more freeboard and seems to have more beam? Let me know what you think.

I guess in the later years, they got around to popping the entire stringer system of a mold.

im building it to last, as I'll likely be giving it to my sister....that is when I find my 25 contender/intrepid/sea vee etc:)

[gran398]

Back in the day, it wasn't OMC.  'Twas Hydrasport of Tennessee. And they took the offshore center console market by storm. Kevlar hulls, lightning bolts, and soft entry. Seacraft was scrambling.

After looking at the aft end left dangling on your 2100....have one US dollar to wager that the 2100 was a 2400, plugged on the length. Have ridden both. Not a hair of difference on the freeboard. Both freeboards are short by today's standards.

If you see a 2400 for sale there....please let me know. Tx!

[Fletch170]

Man, there really isnt much information on the old hydrasport. What I've foubnd in regards to history, seems incorrect. I'd love to see some old brochures....havent found anything.

Let me do some research on the 21 vs the 24, I'll take your bet sir!!!!!

PS: any word on the layup schedule according to your builder? I'm using penske board.

[gran398]

Here is a pic of the core. More can be found 2/3rds down the first page of the Low Cholesterol Version of the Miss D build.

I'll be talking with Chris tonight and get the exact skinny on the layup/procedure etc.

Hang onto my dollar!!
