Hi Cleobeach - Have you ever sailed the BVI? Might be a less 'salty' option than sailing from USVI to SVI (and back?), especially if you are concerned about sea sickness in your group.
We have a beautiful 2019 Leopard 50, 4-cabin cat, with an excellent crew based in Tortola. If our boat is too big, the charter company we have her in has many options for smaller cats and monohulls. Feel free to email me if you are interested, clloyd309@gmail.com.
