Hi Rick, you made a good choice with Model Slipway they build into good strong models, I built a one of their Envoy class tugs last year, it's on here under HMS Enigma, a good size and heavy enough to sail it rough conditions, out of all my boats she is the one I enjoy sailing the most, and the people at Model Slipway are very helpful should any thing be missing in the kit, good luck with your build, I'll look out for it.
Joe.
