Is it what I would call a proper plan for building a model from scratch and part of the plan is missing?

Alternatively, is it a plan that accompanied a kit? If it is then often details of some parts e.g. bulkheads are not shown.

Details of the Designer or the Supplier of the plan would help greatly.

From your list of wants, I have covered everything except the weight as I have not bothered to weigh the thing myself, indeed I have never weighed any of my models. Indeed one of them was Plaxtol which is my version of David Metcalf's Plaudit. With just the motor batteries, speaker for the sound unit etc., I had visions of the thing sinking but the bathtub test revealed that it sat in the water without even the need to include any ballasting. However, going back to offering in the November 2023 magazine it is a bit heavy as it contains 4 Kg of sheet lead to achieve a Freeboard of 20mm, but on the drawing I have recommended a maximum Freeboard of 30mm as anything above 30mm would (in my opinion) look unrealistic.

Regarding the Free Plan due to be included within the November 2023 issue of the magazine, and following earlier discussions on this Thread, I have sent an email to Lindsey, the editor including the following two requests:

Calibration Scale(s) in both Metric and Imperial added to the border (Horizontal and Vertical) of each sheet of the Plan: Metric in 25 mm increments with every fourth one identified i.e. 0 - 100 - 200 mm etc on the Bottom and Left Hand edges and Imperial in 1 inch increments with every fourth one identified i.e. 0 - 4 - 8 - 12 inch etc on the Top and Right Hand edges.

Define the Overall (O/A) Length and O/A Beam of the model together with the extremities for each. This would be best done on the Plan View i.e. looking down of the model from above and only needs to be shown once. Both the O/A Length and the O/A Beam should include any protrusions from the main hull. So for Plover the protrusions to be included in the O/A Length are the Pusher Knees and Pads at the Bow and the tip of the Rudder at the Stern. For Plover, the O/A Beam is just the width of the Hull as there are no protrusions but on some models there could be rubbing strakes and/or spray rails that protrude from the Hull.

I would suggest that for anyone to consider purchasing a plan to your design, they would need to see some images of the completed model on water. I scratch build model boats using my own plans and in reality you get so far with the design and then commence the build with the remainder of the design evolving as the build continues. Also as you would be competing against the likes of Sarik Hobbies, your design would I think need to be something unique which is not already covered by the proven designs in the Sarik range,

The free plan for the November 2023 edition is my creation. Lindsey has the build guide, the images to accompany it and the plan is currently being CADified. The plan defines the hull dimensions i.e. length and beam. There is also a reference scale with increments of 50mm along one long and one short side of the plan. For those interested, is that sufficient information?

Ray - I would be possibly interested in using foam on a future model. Please could you advise the name, type pf adhesive used and method of trimming to the correct profile, Many thanks.

Any hint of the model? No, but a lovely looking model which maneuvers very well.

I have included three Calibration Scales i.e. O/A Length, Beam and O/A Height. The latter is not something that is normally quoted on plans in the magazine but if it helps I will also quote the measurement for O/A Height, both on the Plan and within the build notes.

I am currently tidying up a package i.e plan, build notes and 25 images to go to MB as a free/pull out plan feature. From previous entries on here, and to keep the "digital" people happy I have on the plan defined the Length O/A and Beam dimensions for the model AND a Calibration Scale with 50mm increments at on both axis of the plan. Is that sufficient data or is anything else required?

Mike - I am into model boats but nothing painted Battleship Grey, but as you appear to have the use of a computer I suggest a session with Prof. Google and see what he comes up with. I had a search on Motor Torpedo Boat and the first image tht appeared had a a large 102 on the side of the hull. Is that what you are looking for? There is a company called BECC that can supply all types of decal.

You could try contacting the RNLI who may have drawings in their archives which you could purchase or provide a donation. I have seen a clip of a gentleman living (I think) in North America who built an Atlantic Class boat from a set of drawings supplied by RNLI for which he made a donation.

Trevor - In response to your question posted 3 June regarding "correct proportions". This is just maintaining the correct relationship between the hull length and beam. So I require a hull 28 inches long by 8.5 inches beam which by dividing one into the other gives a figure of 3.3. Therefore a hull length of 42 inches would require as beam of 12.7 inches to maintain the correct proportions.

I have been using Squadron Filler for years but in trying to replenish my stock, it now seems to be unavailable. I have a tube of Humbrol Filler on its way to me but it is worth asking what make/type of Filler do other modellers favour for repairing small blemishes.

Trevor/Brian - Yes, the hull is a bit too big and the length/beam proportions are not quite right either.

Trevor - I may be interested in the GRP hull should it be unsuitable for Brian to use. I am after a tug hull 28 X 8.5 inch beam or of similar proportions.

Often a plan will give you options to go down the "plank on frame" or "bread and butter" route, with plans by David Metcalf being good examples. I intend to try bread and butter for one of my planned models. Obechi and Bass (Limewood) appear to be the preferred timbers to use. Many modellers, me included purchase wood from a company called SLEC as it is always very good quality.

Check the Sarik Hobbies website. They can supply a wide range of plans for model tugs and many will have featured in MB as a build feature.

Hutch - No familiar with that make of sound unit but have found their website and there is is some info there detailing the assembly of a sound unit. If it is not the same unit as your own, you could try contacting the company which is based in Warwickshire.

Andrew - You mentioned your local boating pond so have you tried asking those that use the pond. If it is a club that use it they are normally very helpful. Sadly model shops are getting less and less, so anything recommended to you will (most likely) need to be purchased on line.
