Help Identifying military 36 foot inverted V hull

[Argonaut]

I have purchased what apears to be an EX- Military welded Aluminum Hull boat...Just over 35 feet long....It has a 12 foot beam on the hull with wings on the stern that bring the beam a little over 14 feet. It has an inverted V hull design. It may have been Jet powered at some time (cutouts in Transom Welded up) but it now has V drives......Square bow that comes off the nearly catamaran bow section and continues to the inverted V stern. The boat is open now without superstructure.......Engines mounted in extreme stern...Welded in the stern is 36UB697, I know military boats very well but have never seen anything like this.....I have photos if anyone would like to see.....The seller had been told that it was some sort of riverine craft (maby a prototype?)

web search " riverine craft " USMC topic riverine boats. A 35' RAC is shown had 2 diesels / jet drives.

I think I can help you with identifying this hull, I believe I know what type of riverine craft it is but I need a little more info. Please let me know if you are still interested.

no not used by special forces,,,but the wings were probably used by divers to get back on board,probably used by marine fisherys or park and game commisions,,,but definantly not special forces,,,longliner

Gentlemen,
This is a U.S. Navy Special Forces boat. In fact it is a Vietnam-era Medium SEAL Support Craft (MSSC). Those are not "wings" on the port and starboard side, and they were not used to help divers on or off the boat. They are sponsons that help to stabilize the craft when it was on step.

special forces is army,,,,seal is navy ,,,,sf used rb15,rubber boat 7 on each side ,,one coxman

[SCPO USN]

The key issue here is not the semantics between military forces (SEAL vs SF) but the fact that this is a USN riverine boat, not a park and game commission or marine fisheries boat.

I thought 36UB would indicate 36' Utility Boat, a quick browse around suggested these were made for the Army Corps of Engineers. But it looks like the Senior Chief may have it already.

A little more searching confirms it, I think. You seem to be in posession of one of ten Medium Seal Support Craft built by Atlantic Research in the 60s and 70s http://www.shipbuildinghistory.com/h...smallcraft.htm

This site is in Spanish but it has photos of MSSC further down.

If it's the right boat then that junk on the back must have been added later in life.
