re: 35’6” Razorhead Cat Build

Quick bump and little photo dump.
Wanted to make all the hinges flush mount because it looks better and doesn’t stick up. To do that we had to notch the box tops and bases. Had to do this to allow the Barrel of the hinge to fit. Reinforced the tops with a weld behind the notch. Had to grind on the Fishbox for hours to get the lid to sit right because it was touching the lip in multiple spots and all out of whack. Went through several grinder batteries and discs. Lots of extra time and experimenting but the rest will go a lot faster once the rest of the hinges come in. The friction hinges hold the lids enough to avoid shocks completely. Will be doing top mounts on the livewells to allow for 180 degree opening.

ME, not naval, but I was going to ask about weight. Seems like all aluminum would be heavier than a fiberglass/honeycomb sandwich.

Aluminum boats are typically significantly lighter than fiberglass boats, which is one of the reasons that fiberglass boats typically are more enjoyable to ride in. The other reason is that aluminum doesn’t “give” like fiberglass so you will feel every wave more.

Interesting. I guess I was thinking more about skiffs than offshore hulls, and skiffs don’t take the abuse a deep V does.

Those friction hinges are the shite. Love them.
Glass boats ride better IMO but there are def pros and cons to each.

One thing worth mentioning with the hinges though, need to watch out for galvanic corrosion. Stainless and aluminum technically don’t mix well. Not saying it will be a big issue, but being on the deck and that they will see a lot of saltwater contact, it’s something to think about.

Technically? They don’t at all, talk to an engineer

Lol. I’m just saying stainless bolts get used with aluminum fairly often on boats and seem to hold up decent. TTops, switch plates, etc.
I would be a little concerned being these are on the deck though and will be covered in saltwater pretty much every time it’s used.

I agree with you.
That being said, I’ve used stainless hardware with aluminum on many commercial projects and never had an issue if we use anti seize. shite, even the Coast Guard Cutters have stainless fasteners on the deckhouse and the whole deckhouse is aluminum.
It’s also better to use stainless hardware on aluminum than the other way around.

Use Tef-gel and bed in polysulfide caulk or Pro-Seal.

How’s it work they build the bare hull and you can build it out yourself? Is that normal for them or they will build as little or all out as you’d like?
Posted on 12/13/21 at 10:50 pm to baldona
They typically just make the hull and it’s up to you for rigging and outfitting it

and if you don’t wind up with that shite all over your shirt and in your hair you haven’t used enough.

I'm looking at a grey boat right now with 316 stainless bolts through custom made aluminum hinges.
Posted on 12/14/21 at 8:22 am to DownshiftAndFloorIt
Yeah I’m sure bolts are fine. Like I said aluminum ttops use stainless as well as a lot of other stuff. I was more saying the hinge itself since it’s a bigger surface contact area. Just thought it was worth mentioning. Im sure it will be fine though.
I went down the dissimilar metals wormhole a few weeks ago so it’s just fresh on my mind.

Sometimes I use fabreeka pads under aluminum pieces that have large surface area when bolting to steel. Seems where you really see problems is thin aluminum pieces connected directly to mild steel. The aluminum goes into mega anode mode and goes to shite pretty quickly.
