Deck hatch on Vipermax 7

Thinking about installing a 6" hatch to have a peek downstairs to check all is as it should be and perhaps install a sounder through the planing pad.

About 500 mm up the middle from the inside of the transom looks about right.

Is there a support that runs up the centre of the deck? By knocking it feels like they all run across the boat around here.

Could anyone PM me the contact info for Mike who built the hull?

Cheers

Richard

That's the best photo I have of ours. I can get a photo of the inside and dimensions next week when we are at the boat if required?

Perfect thanks.

I think I can probably work out where you have it from the picture. If you are at the boat at the weekend, it would be useful if you could check whether there are any obstructions a few inches either way fore and aft.

No problem. I haven't looked under there before so can't tell you from memory, and unfortunately I am about 4 times closer to your boat than ours. We probably won't be down there before wed/tues next week, but I do break up on Thursday so we'll see how long we stay before going over.

I cut a hole into the deck of my 6.2 in exactly the same place earlier this year. So rest assured, it'll be OK. One tip I can give you is to place some thin ply wood over the deck where the hole is going. I was worried I was going to mess up the anti slip deck with the Jig saw.

Out of curiosity, what benefits do you get in cutting this access hole? (apart from access to fit a sounder as in Richard's op)
Is there anything specific to keep an eye on down there?

Access to maintain and potentially replace said sounder after fitment. And I think access to some part of the fuel tank but thinking about it all the connections are in the console so that is boll*x.

I will have a look when we're next down there, as we have never opened it for fear of damaging the seal.

Easy access to bail out the water that gets into the hull void from the hole you've just cut out.

My 5.8 has a hole in the same place, under-deck sounder, the spacing to the drain well would be more or less the same I think.

From memory there is a bulkhead (or whatever you would call it) a few inches forward of the hole so I think you'd need to be careful, unless the 7m is different inside but I should imagine the spacing between transom and bulkhead is similar, there would just be more of them.

Now I have my sounder pointing at the bottom I can vouch for it as being a damn good idea
