Re: Aluminium boat building - 25ft fisherman
Thanks for feedbacks guys, also very interesting and technical page! So, seems that best idea should be to test boat first, then lift she up again with crane and weld L profiles accordingly with how boat is running on water! Of course, best way to work is now with hull upside down but also i can con...

Re: Aluminium boat building - 25ft fisherman
This is what I am seeing that looks like a hook. I jist did a finger sketch, which is exaggerated the other way...hook will steal performance badly, the boat will be slower and cost more in fuel..sometimes results can be very bad, so please run a string test, some of the pictures have different col...

Re: Jeffs FS14 LS
This weekend I finally got around to forming the cockpit radiuss with the curved trim. Looks like all 4 trim pieces will work. This was one of the final steps before I can start painting the deck. 20210405_102149.jpg I also started painting the under deck areas. This is totally backwards, should ha...

Re: Aluminium boat building - 25ft fisherman
Because all the boat is made by 5083 plates, i use 6082 for profiles.
6061 is more indicated for other use, for example automotive.
5083 is specific marine grade aluminium.
