That is the most common approach to building yachts 200'+. If greater speed is desired then aluminum below the water line. However, much like many military and commercial vessels, once you pass a certain size, there really is no choice currently as fiberglass is out of the equation. At this time, the largest fiberglass boats I'm aware of are around 164'. I think we'll see that stretched upward a little.

There are minesweepers built of fiberglass, some pushing 200ft if I recall right, but those are specialized applications.

Have any of you ever seen the full stainless steel Detroit 16V-71's that were used in minesweepers? AMAZING to look at! I had aluminum block 6-71's in my boat that were the gensets from WW2 minesweeps. Didn't really like them though because of galvanic corrosion.

You can run the boat up on shore without damage. This type is very popular in the PNW and Alaska

Old School is aluminum, hull and house. House is painted white, hull and deck unpainted. The paint has held up well; splashed in 1993 and not repainted to the best of my knowledge. Only the round handholds on the cabin roof are flaking off and will be repainted. Two of the hatches are wood, one over the rear door and one over the forward cabin. Now going thru stripping and revarnishing both, wish there was no wood at all. Just finished a repaint/refurb of port and starboard doors. She was built by Hike Metal Products in Wheatley, Ontario. Website below if you want to check them out.

Do you have to be ocd about the bottom paint ? Do you repair scratches straight away, or leave them until your yearly haul out?

I had the bottom repainted maybe 3 years ago. My slip is in freshwater (river) and is now covered in green crud. There's a boat repair outfit w/ travelift in Mandeville LA so I'm going there and get her hauled and pressure washed. Then I'll be able to decide on new bottom paint or not. No ocd here about bottom paint. Cabin paint still looks great except as I mentioned in my post.

Check out this boat builder in our area. Been on several of their boats. Had a 24' sport fishing boat made by them for over 15 years. The hull right now is over 33 years old with a new owner. Still in great shape. Keep bottom painted and you're good to go for many years.

For several years, although slowed now, the building of Support Vessels and Crewboats was very busy. Chouest builds their own but had to contract some out. I don't know, but wouldn't be surprised if they used Breaux. I'm not familiar with Breaux.

Next time you're in the BVIs check out the ferries that run from St. Thomas to all the other islands. Most of these ferries are retired oilfield supply vessels that were made by Breaux Brothers then converted to passenger use. These boats still have the original GC placard on the starboard side wall in pilot house area.

We spell it differently, therefore pronounce it differently. I remember being asked by a US contingent on a group cycle ride I did in Ireland to say "aluminium", followed by much sniggering. It dawned on me later USA had messed up the spelling, thereby causing their mispronunciation.
The aluminium trailered boat(commonly called " a tinny") is popular in Australia, especially for fishing. Quintrex were the main proponents, they build large numbers of boats of good quality, design, and durability at reasonable (for Australia) cost.
