I've seen tires roped to the sides for bumpers. I've seen them cut down and used on the bow too. Tires is one of the details that I wasn't sure about. I may add them when I get the boats mounted on the base.
Those plans look interesting.
If not tires..maybe some shrink tubing to simulate these would work well.
Some ship builders rope painted black and dusted with bragdon powders would simulate rusted wound cable really nice as anchors for them.
In HO scale you would be able to get away with using thick sewing thread too.
If you wanted to take it even further sierra west sells HO scale clevis hooks like those in the picture..that would be a little eye catching detail. You can see one better in the second photo in the line on the middle one.
Another nice touch would be a pile of rusty chain up near the bow and some rope.
If you have a Hobby Town USA near you I know they have a lot of ship building details there such as rope and chain and detail bits.
Naming her would be a nice touch too...how about..Sophi or Sophia?
Don't get me wrong...I think you have done a wonderful job and leaving it as is would be just fine....but you could take it up a notch to yet... an even higher level! BAM!!
