USCG 65' Tugboat

My latest scratchbuld project is a USCG 65' WYTL icebreaking tug. I'm building it in 1:32nd scale using plywood. There are a few discrepancies in the various references I have. Length varies from 64' 10.5" to 65' 0.75". Displacement ranges from 60.3 tons to 73.54 tons; giving a model weight between 4.2 and 5.05 pounds. I decided to make a model of the "C" class: longer deckhouse allows better access to the inside; and tripod towing bitt is secured to beams under the deck between two frames.

This class is Diesel powered with a single screw. The normal crew is 7 men. They were designed for light icebreaking, law enforcement, and search and rescue. There were 4 sub classes of this tug. The "A", "B", and "D" classes had short deckhouses, with the towing bitt mounted on the aft side of the stack. The "C" class had a longer deckhouse and a tripod towing bitt further aft.

This is the first time I believe, someone has actually shown how to interpret that dang double drawing thing (body plan). Now it makes sense to me. Finally!! Thanks a lot for this CG Bob!

I got the hull lines and booklet of general plans from The Floatring Drydock about 20 years ago, SOme of the other plans I was able to get from various USCG sources when I was stationed on Governors Island.

Started by making posterboard templates for some of the hull planking. Planking will be 1/16" ply. A few pictures of the full size 65' WYTL's.

Great build...you beat me to it. I've been planning one for some time. I was the 'midshipman master' of the one at Kings Point (named 'Growler' now but I believe was originally 'Bitt') when I attended there. Made me appreciate tractor tugs!
I'll be watching with interest!

Some pictures of the full size boats, from the Coast Guard Tug Association website. I didn't get any work done on the model today, I was too busy working on the CGTA tug APALACHEE.

CGC CAPSTAN WYTL 65601, gives some ideas for the boat stand.



CGC CHOCK WYTL 65602


CGC SWIVEL WYTL 65603 at her decommissioning 14 April 1995.



CGC TACKLE WYTL 65604


CGC TOWLINE WYTL 65605


CGC CATENARY WYTL 65606, anchored for fish call.

CATENARY was later used by the USMMA at Kings Point, NY and named GROWLER.



CGC BRIDLE WYTL 65607



CGC PENDANT WYTL 65608


CGC SHACKLE WYTL 65609


CGC HAWSER WYTL 65610


CGC LINE WYTL 65611


CGC WIRE WYTL 65612

That skeg and fin that supports the prop shaft and rudder I see on two of the tugs is something new to me. When did this come into use?

About the time John Ericsson designed the MONITOR.



Lots of vessels have the shoe or sole plate extending the skeg to the rudder.
TID class tugs

Andrew Jackson Higgins designed EUREKA boat was morphed into the LCVP had a similar skeg design.

lol.... Okay.

I guess I just haven't seen it lately, or on any tug model build on RC Groups.
