Claims: What is claimed is:

1. An inflatable aquatic device; comprising in combination:

plural aquatic members each having a plurality of flexible gas chamber means for containing a gas to provide buoyancy;

each of said plural aquatic members including a rigid frame having a plate region and a plurality of support means extending relative to said plate region;

means for securing said rigid frame to said flexible gas chamber means establishing plural substantially rigid aquatic members;

said means for securing said rigid frame to said flexible gas chamber means including a covering material adapted to substantially encompass said flexible gas chamber means;

said covering material having a plurality of covering formed apertures for receiving said plurality of support means extending relative to said plate means; and

connecting means for interconnecting said plural aquatic members to allow only limited relative movement therebetween.

2. A device as set forth in claim 1, wherein said plurality of flexible gas chambers comprise a plurality of gas chamber tubes secured adjacent one another forming a generally rectangular buoyant member.

3. A device as set forth in claim 1, wherein said plurality of flexible gas chamber means form a generally elliptical buoyant member.

4. A device as set forth in claim 1, wherein said support means includes means for varying the length of said support means.

5. A device as set forth in claim 1, wherein said plate region is substantially centrally located relative to said gas chamber means.

6. A device as set forth in claim 1, wherein said plurality of support means includes plural telescoping tubing members;

spacer means spacing said plural telescoping tubing members relative to one another: and

means for securing said plural telescoping tubing members to said plate region.

7. A device as set forth in claim 1, wherein said means for interconnecting said plural aquatic members includes elastic means.

8. An inflatable aquatic device; comprising in combination:

plural aquatic members each having a plurality of flexible gas chamber means for containing a gas to provide buoyancy;

each of said plural aquatic members including a rigid frame having a plate region and a plurality of support means extending relative to said plate region;

said plurality of support means including plural telescoping tubing members;

spacer means spacing said plural telescoping tubing members relative to one another;

means for securing said plural telescoping tubing members to said plate region;

means for securing said rigid frame to said flexible gas chamber means establishing plural substantially rigid aquatic members, and

connecting means for interconnecting said plural aquatic members to allow only limited relative movement therebetween.

9. A device as set forth in claim 8, wherein said means for securing said rigid frame to said flexible gas chamber means includes a fabric material adapted to encompass said flexible gas chamber means;

said fabric material having a plurality of fabric formed apertures for receiving said plurality of support means extending relative to said plate means.

10. A device as set forth in claim 9, wherein said fabric apertures include fabric tunnels extending along said fabric material for receiving said support means.

11. An inflatable aquatic device, comprising in combination:

plural aquatic members each having a plurality of flexible gas chamber means for containing a gas to provide buoyancy;

each of said plural aquatic members including a rigid frame having a plate region and a plurality of support means extending relative to said plate region;

means for securing said rigid frame to said flexible gas chamber means establishing plural substantially rigid aquatic members;

said means for securing said rigid frame to said flexible gas chamber means including a covering material adapted to substantially encompass said flexible gas chamber means;

said covering material having a plurality of covering formed apertures for receiving said plurality of support means extending relative to said plate means;

connecting means for interconnecting said plural aquatic members to allow only limited relative movement therebetween.

plural paddles specifically configured for use in combination with said plural aquatic members,

each of said plural paddles comprising a shaft having a blade extending from one end of said paddle and a hand gripping region located at the other end of said paddle; and

paddle connector means extending from each of said shafts adapted for engaging the lower arm region of an operator.

12. An inflatable aquatic device; comprising in combination:

plural aquatic members each having a plurality of flexible gas chamber means for containing a gas to provide buoyancy;

each of said plural aquatic members including a rigid frame having a plate region and a plurality of support means extending relative to said plate region;

said plurality of support means including plural telescoping tubing members;

spacer means spacing said plural telescoping tubing members relative to one another;

means for securing said plural telescoping tubing members to said plate region

means for securing said rigid frame to said flexible gas chamber means establishing plural substantially rigid aquatic members,

connecting means for interconnecting said plural aquatic members to allow only limited relative movement therebetween,

plural paddles specifically configured for use in combination with said plural aquatic members,

each of said plural paddles comprising a shaft having a blade extending from one end of said paddle and a hand gripping region located at the other end of said paddle; and

paddle connector means extending from each of said shafts adapted for engaging the lower arm region of an operator.
