At a casual glance is there any way I can improve these SQL Joins?

Most notably the outer apply join that returns 1 row per call from a tabular function that crosses databases


SELECT a.Field1,
              b.Field2,
              c.Field3,
              d.Field4,
              e.Field5,
              f.Field6
		FROM
			[dbo].[vwVessel] a
			JOIN [dbo].[vwVesselOpenPosition] b ON b.VesselID = a.VesselID
			JOIN [dbo].[vwPort] c ON c.PortID=b.PortID
			JOIN [dbo].[tbl_Ref_Port] d on d.PortID = c.PortID
			LEFT JOIN [dbo].[vwUserDictionary] e ON e.UserDictionaryID = d.AreaUserDictionaryID
			OUTER APPLY [dbo].[udtfGetQ88VesselData](a.VesselName, a.IMO) f 
			LEFT JOIN [dbo].[udtfGetUserVesselList](@paramUserID) g on g.VesselID = a.VesselID
		WHERE
			ISNULL(b.IsHide,0)=0
			AND a.UserCompanyID = @paramUserCompanyID
			AND (@paramIsMyVessel = 0 OR g.VesselID IS NOT NULL)
