The recesses were marked on the hull, sort of a raised shape which I drew around with pencil to make stand out. I just used a drill & file to shape them. made the inner bits from scrap plasti card. There is no mention on these in the plans or instructions, so I guess you're either meant to leave them or do what you fancy
Well done Dan, attention to detail.
Having served on two Tribals (HMS ESKIMO 1974-76 and HMS MOHAWK 1962-64 First Commission) the anchor recess (or lack of) were the first thing I noticed on my model and I wondered when you started out on your venture if you would overlook them.
I too used a Deans Marine kit of ZULU to build ESKIMO and must say that I also experienced problems with instructions, marking-out etc, etc. However, I persevered and turned out a reasonable model. But beware anoraks!! Some guy at a boat show argued black was white regarding the watertight door leading to "H" diesel generator compartment.
He swore blind that it shouldn't have been there. (It was the only way in or out of that compartment).
They all know best eh?
Love your Wasp, at 8.8 grams it shouldn't affect stability, but a word of warning, keep everything above the waterline as light as possible, there's not much margin of error along the waterline (unless you raise the boot topping by about 1 centimetre).
Good luck with your project, you seem to be forging ahead on both steam and G6 gas turbine coupled.
Sandy.
