Fish/dive gear storage is about the only thing this boat is short of.

The previous owner of mine had a 6 ft insulated fish box built that sat on the transom (see my photobucket page for pics) I planned to put a teak platform and kicker behind it until I started calculating how much all that would weigh. Plan B: had an aluminum box/platform built. I'll use it for light dive gear storage, but it could easily be a fish box. Will post pics when I finally get everything mounted.

I noticed in Connors pics, his fuel tank hatch is roughly half the size of ours. Ours goes right to the stepdown. I assume yours was the same as Connors before it was cut out. I guess the difference is that we have one tank and you guys have or had 2 and I guess they slid the one under first before installing the 2nd.

That being said, I know you have to rebuild yours and wanted to give you my thoughts. Ours is loosening up at the joint and is a little spongy where it meets the stepdown. It gets a lot of traffic and I think there should be at least 1' of solid floor at the top of the step. Even better if you have more, like Connors.

My opinion is based on the fact that the hatch hasn't really deteriorated much in the last 15 years since she's been under my care and knowing how much traffic she saw in the charter days so it was a little spongy 15 years ago. The rest of the hatch is solid although dipping a little in the middle.

You'll notice I use the words "a little" a lot. My theory is, when I start to use the words "a lot" a lot, thats when the major resto will begin.

My desk top computer is down so it may be a few days before I'm able to post any pictures showing what I have done with the floor and deck hatch on the 25 seafari. It has more support then the original design and will not ever sag or get spongy...ever again ;)

Hopefully this will work as I'm posting from my lap top wireless modem. Some more shots showing the area were I reinforced the deck and area were the big hatch will sit. In the original design the deck sits on top of two stringers that sit about 5 foot six inches apart. The hatch that accesses the fuel cell sits on a lip in the middle of this large span.

Although the deck on this boat is solid the one on my other 25 seafari is spongy in this area because of a lack of support under the deck and water intrusion in the deck core. In the pictures below you can see were I've added a 1 1/8 plywood encapsulated in glass and bonded to the hull. Both the deck and the new hatch will sit on these supports offering more support to the deck and hatch as well.

Adding flange to the mold. The base of the mold is 1/2 inch plywood sanded on one side. I did not use mdf because it is
too flexible to for such a large hatch.

Mold ready for lay up. There is 4 coats wax and 6 coats PVA over this.

OR...you could do THAT. I wasn't even thinking that you could do it that way. That's going to turn out sweet.

That surely covers what I was trying to convey to you about the top of the step needing to be solid.

You may have read what I said on Connors thread about the drainage in the stepdown. I was just curious as to what you had planned for yours.

Brandon

BTW I wasn't rushing you on my last post but I'm sure Pavlov's dog is happy now :D

Hey Strick,

I like your thru-hull mounting block work, very neat and clean. Is it for the DS-ducer? I've been led to believe that it might be worth the extra effort to set it verticle to the waterline with a counter cut set of wedge blocks mounted one on both side of the hull to offset the deadrise. Just asking.

Re: I Need A Shrink !
 
Thanks guys for the cheering and input.

Brandon- I did read what you and Conner had said about water drainage in the step down area. I'm still thinking about how I want to tackle that problem. Part of the fuel tank will sit under the step down. I was thinking some 1" flush mount SS round deck drains with a bib for a hose under the deck. This will allow water to drain around the fuel tank and into the bilge. This was my first thought...I just got to look at different kinds of deck drain hardware and see what will work best.

Lance- The block is for the seacock. I'll be putting in a flush mount transducer with a tilted element somewhere in the engine compartment.

Despite this boat being 25 feet long there sure is not much room for things. I decided to take Spidercrabs advice and not make things too complicated for myself....so I've given up on the idea of an in deck fish hatch. Did not want to move the fuel tank forward and change the center of gravity. The fuel tank will be about 7 feet long and will be shaped similar to the hatch so it dips under the step a foot or so. There will be a small fresh water tank just forward of the fuel tank.

Beautiful work Strick! Fast too!
Spidey`s right about the convenience of fish bags, but I surely like a nice box to incarcerate green meanies in a hurry. A nice green Cobia broke a light spinner years ago, and almost got me too. What about a box in the transom cap centerline? Flip flop hatches?
Cheers,

great idea and a transom door too :cool:

Re: I Need A Shrink !
 
Theres just not enough room in the transom cap for any kind of storage like you see in other seacrafts.
