American Marine Laguna 10 metre

The 11 meter is a very strong boat, and sea worthy too. They weigh as much as a Bertram or Hatteras of the same size, but are a more cabin boat. Strong indeed.
Deep hull all the way of 20 degrees plus. They need some high torque power, but can cruise at 18 knots in quite rough conditions. Down, up, or side wind....
We have half a dozen of them over here, and all have nice lines.

FYI American Marine is Grand Banks, and Laguna was more there planning line in the eighties.
The ones in Malta have had little to no trouble. Never seen one with structural issues and even osmosis is quite rare. Considering the eighties boats had a lot of issue with this.

This boat is one of my favorite topics as our family had a Laguna 10 metre from 1976 to about 1982. The hull is well built and will take much bigger seas than you would imagine. The deep-vee works its' magic and that bow would never bury, although the speeds back then are not as close to todays.

Went through two sets of GMC Toro-Flow Diesel Engines that American Marine marinized, were pretty much garbage, heavy smokers, and the transom was always black due to a significant "station wagon" effect even with the underwater exhaust! The Hull is worthy of a repower, and the Robert Dorris designed hull was way ahead of its time, as well as some opf the trick American Marine Interior features.

Our family of five used the hell out of that boat and thought nothing of going 50 - 70 miles offshore. Unfortunately, the engines were the plague of the Laguna's, as there were no modern high power to weight engines available at the time. The CAT 3208's were heavy and too big, although some managed to shoe horn them in. This would be a great repower candidate for a more compact Yanmar/Volvo Penta/Cummins.

The small rudders didn't seem to affect the handling and the cable (manual) steering had very positive feedback. I even drove her back home from 55 miles offshore on one engine in 10 - 12 foot seas manually (no autopilot) without too much effort. (as I recall!)

After one round of rebuilds, we lost power on the way back to the marina and upon swinging opening the stbd engine hatch (with wet bar included), saw fuel from a broken copper fuel line spraying forward and luckily not backwards towards the turbo. Unfortunately, this was to occur again for the next owner a few years down the road, and I recall thick black smoke on the horizon as she burnt to the waterline and met her fate on the bottom of the ocean - something that happened to more than one Laguna 10 metre with those engines.

I do recall the decks feeling a bit "spongy" and I believe they were balsa cored, something to look out for. All said and done I loved the ride and layout, it really is a capable pocket cruiser

I have a 1972 11.5 and the previous owner is one of the founders of American Mar. He repowered it in 2022 with Ford 351W producing 440 hp each side. I am 82 years old and I love it.
