Testing a simple mock-up to see if it fits

That's quite a project. I'm not adventurous enough to take on a project like that and appreciate those who have the skills and the know how to do it.

Please keep sharing the photos. I'm enjoying them.

I'm surprised by the color of the stringer. It looks like it has been wet and is starting the early stage of rotting. It is kind of a punky black color. Anyone else wonder about that?

Be sure to reinforce the area you removed the stringer. Based on what I know about fiberglass it can fail without notice and at that point you sink. The glass fibers crack and you can not see them fail. Fiber glass used to be a popular crude oil storage tank liner. It was very good until the tank had excessive settlement. I have never put one in; but have watch marinas do it. A good marine uses the correct hole saw. I saw one marina use a Sawzall. It did not look pretty.

With all due respect WHY not? I have had lots of RVs during the years but now I have this boat. I have driven different boats for many years so I’m familiar with that for example this type

Combat boat 90 are easy to drive but my 260 isn’t easy when I have wind from the side when I go to dock.

Do you have a reversing camera on your car or other technical aids? If you have it why?
Maybe you should cycle instead! ;-)

Nice project, keep us updated.

A single engine boat, especially an I/O can become a handful for anyone at times, no matter how good you are. If you are ok with the time and money, why not.

I’ve never NEEDED a thruster on my 260, but man have there been sooooo many times it would have been AWESOME to have.

following and plotting

For anyone interested. There's an option to ignore any specific member of the forum...nice to have sometimes.

This is something I've wondered about in the smaller cruisers. Just last weekend we had winds blowing 20mph plus 90 degrees to the slip. My single engine 280DA with the full camper canvas up was a BEAR to get backed in! It took about 5 shots, but I finally got it with a brief lull in the wind speed.

Definitely will be interesting to see the completed project. A few questions.
- what is the purpose on the centerline beam that is in the picture? The one that you had to remove a section of.
- Was there a layer of plywood/fiberglass on top of that beam that you had to remove?
- Was there foam filling both void spaces (above/below the fiberglass)?
- It looks like the carpeted platform that you sectioned out has screws holding it on.? I see 4 in the photo. My 2000 260 doesn't have these, but maybe they are hidden in the carpet. Would it of been easier to just remove the whole platform to get access to the compartment?
It'll be good to see how you finish this off. Will you be sealing off the chamber to protect from water intrusion? Also I'll be curious to see the completed project on the exterior as well. It'd also be good to know if there's any effect on planning performance of course. I saw a 280 once with thrusters and the skipper of that vessel said the thrusters are above water when planing. Probably the same for you. Thanks for posting all of this.

I’ll try to answer your questions.

The centerline beam are a support for the floor and it did only have fiberglass in the bottom against the hull.
Whole are where filled with foam and it was wet probably due to condensation.
It’s not screws you see, it’s fastening points for a carpet.
I will not seal this of because I need to reach the electric motor for maintenance so there will be a hatch in the floor.

This installation will not affect planning because the tunnel will be over water when planning.

I believe he is talking about the little step up under the vee berth where vee berth table mount is. You can see it in the the pictures in the first post(s). It separates two foam sections and looks like it supports the table leg mount.
