Thinking about extending my Maritime Patriot 23 to a 26

It's a 2006 - Patriot 23'-3" with 8'-6" beam. Would like to have a Patriot 25, but new is too expensive and can't find a used one for 2 years now.

Really like the boat for a great all-around boat for the Chesapeake but would like a little more room and waterline to span the chop better. Would also like to bring the cabin console back about a foot and increase the gas capacity. I really like the transom and splash well design, so I want to keep that part. The boat is also a good following sea boat, so I want to keep the original transom shape (slight curve) as well.

Plan is to cut just forward of the splash well and add in approximately 2'-9". The stringer system is a foam filled grid and not traditional stringers so I figure I'll have to shape foam inserts and glass them between the grid structure for my extension after I mold the hull itself.
the hull shape is very close to the same through the area I plan to cut.

Any thoughts, suggestions or concerns are welcome.

I will be working with a very experienced fiberglass guy on the eastern shore f VA. I'm an hour north on the eastern shore of MD.

Thanks

I have stretched several boats, and while they were all successful, the most common gripe was that they wished they’d added another two or three feet while they were at it.
It’s a big and expensive project, and great care must be taken to maintain the bottoms’ lines.
The first one I did was on a fast deep vee hull, so I made all the cuts at angles, bottom and sides to spread the loading .
Id cut the top of the existing stringer out well beyond the joint, remove the foam and glass the joint inside and outside.
Foam can be replaced after glassing, and top glassed over.
How will lengthening of the hull surfaces be accomplished?
That can become complicated if the hull is not perfectly straight in the hips, including the gunnel height.
Edit:
I should add that unless you have unlimited time and funds, and an itch to itch, you’d be far happier to simply trade up to a boat that checks your boxes.

 

Thanks for the reply kapnD. Good advice.

The hull sides and bottom in the area I plan to add in length are pretty constant fore and aft. So I think that will work out.

As far as trading up to a bigger boat, I've been looking for a 25 Patriot Maritime and they don't make any bigger than 25. Never seen one for sale, but that could change. I really like the way Maritime does the walk around pilot house which for my use is a must. I haven't seen that on other boats around me. I guess an option would be to find a hull I like and build the walk around pilot house. But that will be a ton of work too since there needs to be a step-down area below deck inside the cabin.

 

Interested in any other comments from someone who was done this to a similar or any boat. Thanks

 

A comment on your fuel fill hose
It appears that it drops below the height of the tank. When filling, this hose will fill up completely before the fuel goes into the tank and will not allow for venting through the filler
hose while filling. While the vent line allows venting ie the displaced air to allow for the fuel to fill, a result could be that the fuel process will be very slow.

 

I appreciate the comment. I see what you’re talking about with the fill line. So far it’s been easy to fill. No different than any of my other boats.

I will check the line position. The fill is at the top of the splashwell which is about 10” above the tank. Possibly the hose in the pic is laying low until the deck and splash well is installed.
Thanks

 

Be sure you take a hard look at extending more, entertain the idea, please.

Cheers

 

It is difficult to see the direction of the arrow in your tank picture but if it the same as the same as the Attwood shown below, it appears that it is installed backwards.

 

Barry- The pic of the grid and tank is not from my boat but another build. I have no issues fueling. Thanks

BB- Do you mean that I need to extend it more than 2'-9" ?

Very interested to know from someone that has an extended boat or been in one if the following sea characteristics changed with the extension and is so, better or worse. My 23 is good in a following sea and I don't want that to suffer. I plan to cut the boat just forward of the splash well to keep the entire transom intact.

Thanks

 

Ya, sorry, I wasn't very clear, that's exactly what I meant.
What a shame to extend 2' 9" only to realise 4' or 5' may have worked better.
I've seen it happen before.

P.S. Where is "21087".

 

I hear you. I’ve considered longer. Maybe 4’.

21087 is my old zip. Kingsville MD.

I now live on the eastern shore of MD.
