will the albin 27 plane?

[tomcat rio]

just curious.
somebody told me it has a displacement hull. max speed on brokerage boats is usually not much more than 12 kts wiht the 157 hp engine.
i don't think i've ever seen one with any more power.
seems to me it would be a screamer with a 240 yanmar or something similar if it did plane.
what would be the properties of the 27's hull that define it as a displacement type. i suppose dead rise has somehing to do with it.

relevant link... go to 'articles' and then 'albin 27 repower, ebb tide':

I believe the A-27's are displacement hulls. This means that they do not produce lift and thus, they are limited by their "hull speed". Hull speed is essentially the boat's terminal velocity when traveling through the water. You ought to be familiar with that, given your aviation background.

The characteristics of a displacement hull are primarily that it has no surface which trades resistance for lift, such as strakes, a broad flat stern, or hard edges. A canoe is a perfect example of a displacement hull. It provides very little resistance to water as it passes through it, making it very efficient at low speeds, but no matter how much power you put on it, it isn't going to hop up on a plane and reduce it's wetted surface area.

There are literally hundreds of old displacement hull trawlers out there. They were very popular in the 70's and 80's. Most were made in Taiwan, including Albins. The build quality on those older "Taiwan Trawlers" varies, but is, on the whole, sub-par. They used outdated materials and construction techniques to produce cheap, efficient boats. Despite that, their simple, efficient design ensures that they maintain a large dedicated group of followers who are willing to put in the hours of maintenence necessary to upkeep these older boats.

Actually the 27 WILL plane, in it's own funny way. If you strap enough hp onto anything it will eventually skip across the water.

I had a Westerbeke 100hp in my Albin 27AC. Clean bottom & lightly loaded it would give 13kts in smooth water. There is a rare 27 Sport in Bermuda with a Cummins 210hp. Wanna go skiing behind an Albin? I have measured this one, GPS, at 18kts.

The 27 has an odd shaped hull. It has a full keel, just like any downeast hull. It has soft chines, also not uncommon. What sets it apart is the 'hook' in the bottom. You have to look carefully from the stern but there is a 'hook' on the flat after surfaces which tends to make the boat run very flat & not dig a hole in the water like others do without tabs.

If it has a hook, then it's definitely not a true displacement hull. Sounds more like a semi-displacement.
