Due to shutdown and a 'non-availability' of certain items, I decided to dust off a hull and semi kit that I bought from Mobile Marine Models. It is called Euro-Girl. Available in single and twin kort drives I have gone for the twin Steerable Korts. Driven by MFA Torpedo 500 with gearboxes.

Today I went on a thorough examination of the Semi Kit Parts 1,2 and 3.
The Hull is a chopped strand GRP Hull and is extremely well made. It is thick enough not to twist and is approximately 2mm -4mm thick. The thick parts are where it is going to take the load. It is finished off in a rust colour which suits a tug because if you scratch the paint this rust colour will show through just like a working boat! The Cut outs are molded in inluding the propshaft(s) and steerable Kort(s) Here you make a decision of 1 Kort or 2. I am building a 2 kort units with 50mm props.
The plans are OK but be aware you have to read the plans and 3 pages of sketches carefully, then proceed with a list of how to tackle it. The Instructions are only a guide in general Tug building from MMM.
The Templates are on A3 Sheets which I have copied and laminated ( easy to cut around. Be aware that the templates are approximate.
The Main Plan is A0 and like all my drawings I print and laminate expensive but worth it, in fact the drawing copy looks better than the original!
I decided to build fully with wood as you given an option of wood/styrene or wood.
The wood is of good quality and comes complete with brass wire and styrene rod.
They have allowed about 20% over so if you make a mistake there is enough to cope. As a lot of small pieces are required I would suggest you search your scrapboxes for bits this save cutting into a large sheet.
My opinion for what it's worth is a good kit but not for the faint hearted! Some building experience is required and you must be able to read a technical drawing properly.
By the way one photo is one part of my workshop showing Sea Queen (waiting for ZAP Epoxy) and Sea Commander waiting for paint ( Lockdown!)
That's all for now.

Apologies
Heres part of my Workshop

Apologies all,
I am busy moving a Colchester lathe out of my workshop as it has been sold! Nearly 600Kg not for the faint hearted.
Update to follow

I did some research into Mobile Marine Models and their building and came across an build on MMM's Portgarth in Model Boats Mayhem. It makes interesting reading so I will be checking everything it might be a long build. The advantage is that 'Euro-Girl' doesn't exist in full size and is a pro-typical model but I am a bit worried about hull accuracy and finish. So I will set it up on my Milling Machine and check with the DRO's. Also must look at access, template accuracy etc.
