Xf 20 strength uses and mods

Post by Guest » Wed Jan 08, 2020 4:14 pm

I am new here and trying to decide if the xf 20 could be used as a work boat for my commercial fishing. I am in love with the idea of the weight of the finished boat. With my 40 hp tiller outboard, and the hull weight, it should be between 600 to 700 lbs. I currently hand pull a 17' McKee craft with a 130hp Honda 4 stroke through 1000 hooks, or a little over a mile of mainline.my current rig is 1700 to 2000 lbs before any catch is aboard. I average between 500-1000 lbs catch weight each day I fish. I can't find a boat builder around anymore, another dying occupation. All the commercially avail platforms I've considered are too weighty, so I'm down to building my own. I've done plenty of construction work from furniture to a timber frame room addition, so I'm not scared of the project. I just don't know enough about engineering to figure a boat builder out. Does anybody have any knowledge of the weight carrying abilities of this hull design? I know and accept the flat bottom ride. I'm searching for a stable pickup truck for the water. Thank yall in advance for your help and input.

That is the XF20 Red Alert in Texas. On the forum somewhere, there is another picture of that boat in Florida with more people, 20+.
Capacity is not a problem at the dock, the XF20 will not sink BUT she is designed as a light boat and should not run at full speed or in a shop with such a load.
The weight that is listed in the study plans is for the original version, a light boat with no sole, stringers are apparent. That version is fine for inshore fishing with up to 4 persons.
Most builders go for the sole version which is stronger but heavier: around 600 lbs for a finished hull.
It is still not a work boat.
I designed a version with more frames and stringers, same XF20 but stronger structure. I can include those drawings in a plans package but the weight will again increase.
Later, I designed the XF22 as a guide boat: made to take up to 6 persons and designed for professional use. It is a much stronger hull, still shallow but again, heavier and more costly to build.
Look at the study plans:
https://boatbuildercentral.com/StudyPla ... ?prod=XF22.

The XF22 is a larger redesigned XF20 with an egg crate structure but I focused on weight: lots of lightening holes and thin ply wherever possible. Built with an Okume ply core by a good builder, the hull weight could be kept around 600 lbs. The plans list a heavy duty versions with a hull that is about 800 lbs.

With 1,000 lbs of fish plus the ice plus lots of gear, I would not pick a light hull.You are going to have a minimum displacement of 2,000 lbs, maybe 3,000. 200 lbs difference in the hull is less than 10% of the total weight but you will have a stronger hull.
Alos, take in account that many builders end up with a heavier boat than what I calculate because they use heavier wood than Okume, add a layer of glass here and there and use much more resin than necessary.
I would build either the XF20 sole version with heavy duty reinforcements or build the XF22.

Have you considered an OD18 or (larger) the HM19 with no superstructure? Should ride a little better than the XF20 and if anything tougher. The HM19 has a 18mm (3/4") bottom plus the glass.

You don't say where you fish; that could effect things.

Welcome to the forum and good luck with your boat building project.

Another good choice to consider might be the GP-21. It is a very versatile boat and can be laid out a variety of ways. It also will likely have a better ride in a chop than the XF series.

Thank you all for the replies and help. I fish the Albemarle sound and adjoining rivers, and the Pamlico sound. I guess I am getting older and wishing for a perfect world. I have come to realize why there are no old fisherman on the water here. Guess I was hoping someone may have figured out something that would have made my life on the water a bit easier/career longer. Thanks again for the input.

Best way to have a longer and easier career as a commercial fisherman is to win the lottery and move to Kansas. :help: :lol:
